Fire Pump (Main + Emergency)

critical IMO Required 304 / 304 models (Inspector)

SOLAS requires two independent means of pumping seawater into the fire main: a main fire pump and a fully separate emergency pump outside the space that could disable the first. Neither may share a single point of failure with the other.

What makes this type

The fire pump supplies seawater under pressure to the ship's fire main, feeding hydrants, hose stations and fixed fire-fighting systems throughout the vessel. What sets this equipment apart from other engine room pumps is the redundancy requirement behind it: SOLAS calls for at least one main fire pump plus an independently powered emergency fire pump, sited in a different space so that a single fire or flood cannot take out both. The emergency pump has its own dedicated engine or motor and its own sea suction and sea chest, entirely separate from the main pump's arrangement.

Main and emergency fire pump arrangement — Shipboard arrangement of the main fire pump in the engine room and a fully separate emergency fire pump in another compartment, both feeding the same fire main.

Main components

Pump unit

Typically a centrifugal pump, self-priming or fitted with a priming system, sized to deliver the required capacity at the pressure needed to reach the most remote hydrant on board.

Prime mover

The main fire pump is usually driven off the ship's electrical supply or directly by a diesel engine; the emergency pump has its own independent diesel engine or, on some vessels, a dedicated generator, so it works even with the main switchboard dead.

Sea suction and sea chest

A separate sea chest for the emergency pump, positioned so flooding or damage affecting the main engine room does not also disable the emergency supply.

Fire main and isolating valves

The pump discharges into a ring or branched main fitted with isolating valves, allowing a damaged section to be shut off without losing pressure to the rest of the system.

Selection / Sizing

Required capacity is set by SOLAS in relation to the vessel's cargo pump room and machinery space dimensions, expressed as a formula linking pump output to the ship's size and type rather than a flat figure. The pump must maintain a minimum pressure at the two highest or most distant hydrants running simultaneously, and the emergency pump's capacity is set as a defined percentage of the total required main pump capacity, not simply matched one-for-one.

Regulations / Class

SOLAS Chapter II-2 sets out the number, capacity, and independence requirements for fire pumps, including the location of the emergency pump outside the category of space it is meant to back up. Class surveys check pump capacity and pressure at the fire main at intervals set by the survey scheme, and the emergency pump's independent power source is specifically verified as unaffected by a black-out condition in the main machinery space.

Typical faults

Loss of prime on a self-priming pump — no water delivered on start, often traced to a worn priming device or air leak in the suction line.
Emergency pump's dedicated engine not run-tested regularly — fails to start when actually needed after months of inactivity.
Fire main isolating valves seized shut or open — a damaged section cannot be isolated, dropping pressure ship-wide.
Sea chest strainer fouling — reduced flow and cavitation at the pump, masked until full capacity is demanded.

What to look for in a supplier

Certified capacity and pressure curves matching the vessel's SOLAS-required figures, not generic pump data.
Confirmed independence of the emergency unit's power source from the main switchboard.
Materials suited to continuous seawater service, since this pump must start reliably after long idle periods.

Run the emergency fire pump under load on its own weekly test, not just a no-load start; a pump that starts but cannot build pressure will pass a casual check and fail the day it matters.

Common Failures & Inspection Points

Area: Mechanical seal (mechanical face seal) - wear, leakage, surface roughness
Check: Visual inspection: leakage quantity 1-10 ml/24h is normal. If >20% water content in oil chamber after 1 week of operation, seal is defective. Seal faces NOT to be touched with bare fingers. At standstill: inject silicone oil between pump housing and coupling to prevent face adhesion.
Area: Bearing (ball/roller bearing) - wear, bearing clearance, lubrication film breakdown
Check: Check circulation lubrication: relubricate SKF LGHP2 grease using grease gun. Measure bearing clearance with caliper per workshop guidelines. After 100,000 operating hours perform replacement. Motors up to 11 kW are permanently lubricated (no relubrication required). Abnormal vibrations/noise indicate bearing wear.
Area: Impeller - wear, cavitation, erosion, wear rings
Check: Visual inspection for: erosion, pitting, cavitation damage, cracks, dents or irregularities on impeller blade leading edges and hub. Inspect wear rings (front/rear) for scratches/deformation. Measure clearance between impeller and pump housing with caliper. Decrease in flow rate/pressure build-up/current consumption indicates impeller damage.
Area: Motor - wear, bearing wear, heat development, contamination
Check: Motor to be inspected visually and cleaned regularly for adequate cooling. In dusty environments inspect more frequently. Monitor temperature (elevated heat development = early fault signal). Detect bearing wear through vibrations/noise. Compare current consumption vs. rated value. Motor bearings in 2/4/6-pole motors up to 11 kW are maintenance-free lubricated; larger motors to be lubricated regularly.
Area: Öl im Pumpenraum - Verschmutzung, Wassergehalt, Alterung
Check: Check oil level after 1 week of operation (after seal replacement). Monitor water content: >20% water means seal failure. Oil change every 3,000 operating hours or 1x/year (Shell Ondina 917 or similar). Inspect oil colour, odour, turbidity for contamination/combustion products.
Area: Corrosion in seawater applications - material degradation in corrosive environment
Check: For seawater/marine environments: pump must be designed in high-grade stainless steel (EN 1.4517 Duplex, AISI 316) or titanium. Perform visual inspection for surface rust, pittings, discoloration. High-grade stainless steel designs (EN 1.4408) for T>40°C and chemical fluids. Use special seals (Super Duplex) and sealants for aggressive media.

Common Failures & Inspection Points

Area: Mechanical seal (mechanical face seal) - wear, leakage, surface roughness
Check: Visual inspection: leakage quantity 1-10 ml/24h is normal. If >20% water content in oil chamber after 1 week of operation, seal is defective. Seal faces NOT to be touched with bare fingers. At standstill: inject silicone oil between pump housing and coupling to prevent face adhesion.
Area: Bearing (ball/roller bearing) - wear, bearing clearance, lubrication film breakdown
Check: Check circulation lubrication: relubricate SKF LGHP2 grease using grease gun. Measure bearing clearance with caliper per workshop guidelines. After 100,000 operating hours perform replacement. Motors up to 11 kW are permanently lubricated (no relubrication required). Abnormal vibrations/noise indicate bearing wear.
Area: Impeller - wear, cavitation, erosion, wear rings
Check: Visual inspection for: erosion, pitting, cavitation damage, cracks, dents or irregularities on impeller blade leading edges and hub. Inspect wear rings (front/rear) for scratches/deformation. Measure clearance between impeller and pump housing with caliper. Decrease in flow rate/pressure build-up/current consumption indicates impeller damage.
Area: Motor - wear, bearing wear, heat development, contamination
Check: Motor to be inspected visually and cleaned regularly for adequate cooling. In dusty environments inspect more frequently. Monitor temperature (elevated heat development = early fault signal). Detect bearing wear through vibrations/noise. Compare current consumption vs. rated value. Motor bearings in 2/4/6-pole motors up to 11 kW are maintenance-free lubricated; larger motors to be lubricated regularly.
Area: Öl im Pumpenraum - Verschmutzung, Wassergehalt, Alterung
Check: Check oil level after 1 week of operation (after seal replacement). Monitor water content: >20% water means seal failure. Oil change every 3,000 operating hours or 1x/year (Shell Ondina 917 or similar). Inspect oil colour, odour, turbidity for contamination/combustion products.
Area: Corrosion in seawater applications - material degradation in corrosive environment
Check: For seawater/marine environments: pump must be designed in high-grade stainless steel (EN 1.4517 Duplex, AISI 316) or titanium. Perform visual inspection for surface rust, pittings, discoloration. High-grade stainless steel designs (EN 1.4408) for T>40°C and chemical fluids. Use special seals (Super Duplex) and sealants for aggressive media.

Measure clearance between impeller and pump housing with caliper. Decrease in flow rate/pressure build-up/current consumption indicates impeller damage.
Area: Motor - wear, bearing wear, heat development, contamination
Check: Motor to be inspected visually and cleaned regularly for adequate cooling. In dusty environments inspect more frequently. Monitor temperature (elevated heat development = early fault signal). Detect bearing wear through vibrations/noise. Compare current consumption vs. rated value. Motor bearings in 2/4/6-pole motors up to 11 kW are maintenance-free lubricated; larger motors to be lubricated regularly.
Area: Öl im Pumpenraum - Verschmutzung, Wassergehalt, Alterung
Check: Check oil level after 1 week of operation (after seal replacement). Monitor water content: >20% water means seal failure. Oil change every 3,000 operating hours or 1x/year (Shell Ondina 917 or similar). Inspect oil colour, odour, turbidity for contamination/combustion products.
Area: Corrosion in seawater applications - material degradation in corrosive environment
Check: For seawater/marine environments: pump must be designed in high-grade stainless steel (EN 1.4517 Duplex, AISI 316) or titanium. Perform visual inspection for surface rust, pittings, discoloration. High-grade stainless steel designs (EN 1.4408) for T>40°C and chemical fluids. Use special seals (Super Duplex) and sealants for aggressive media.

Common Failures & Inspection Points

Area: Mechanical seal (mechanical face seal) - wear, leakage, surface roughness
Check: Visual inspection: leakage quantity 1-10 ml/24h is normal. If >20% water content in oil chamber after 1 week of operation, seal is defective. Seal faces NOT to be touched with bare fingers. At standstill: inject silicone oil between pump housing and coupling to prevent face adhesion.
Area: Bearing (ball/roller bearing) - wear, bearing clearance, lubrication film breakdown
Check: Check circulation lubrication: relubricate SKF LGHP2 grease using grease gun. Measure bearing clearance with caliper per workshop guidelines. After 100,000 operating hours perform replacement. Motors up to 11 kW are permanently lubricated (no relubrication required). Abnormal vibrations/noise indicate bearing wear.
Area: Impeller - wear, cavitation, erosion, wear rings
Check: Visual inspection for: erosion, pitting, cavitation damage, cracks, dents or irregularities on impeller blade leading edges and hub. Inspect wear rings (front/rear) for scratches/deformation. Measure clearance between impeller and pump housing with caliper. Decrease in flow rate/pressure build-up/current consumption indicates impeller damage.
Area: Motor - wear, bearing wear, heat development, contamination
Check: Motor to be inspected visually and cleaned regularly for adequate cooling. In dusty environments inspect more frequently. Monitor temperature (elevated heat development = early fault signal). Detect bearing wear through vibrations/noise. Compare current consumption vs. rated value. Motor bearings in 2/4/6-pole motors up to 11 kW are maintenance-free lubricated; larger motors to be lubricated regularly.
Area: Öl im Pumpenraum - Verschmutzung, Wassergehalt, Alterung
Check: Check oil level after 1 week of operation (after seal replacement). Monitor water content: >20% water means seal failure. Oil change every 3,000 operating hours or 1x/year (Shell Ondina 917 or similar). Inspect oil colour, odour, turbidity for contamination/combustion products.
Area: Corrosion in seawater applications - material degradation in corrosive environment
Check: For seawater/marine environments: pump must be designed in high-grade stainless steel (EN 1.4517 Duplex, AISI 316) or titanium.

Common Failures & Inspection Points

Area: Mechanical seal (mechanical face seal) - wear, leakage, surface roughness
Check: Visual inspection: leakage quantity 1-10 ml/24h is normal. If >20% water content in oil chamber after 1 week of operation, seal is defective. Seal faces NOT to be touched with bare fingers. At standstill: inject silicone oil between pump housing and coupling to prevent face adhesion.
Area: Bearing (ball/roller bearing) - wear, bearing clearance, lubrication film breakdown
Check: Check circulation lubrication: relubricate SKF LGHP2 grease using grease gun. Measure bearing clearance with caliper per workshop guidelines. After 100,000 operating hours perform replacement. Motors up to 11 kW are permanently lubricated (no relubrication required). Abnormal vibrations/noise indicate bearing wear.
Area: Impeller - wear, cavitation, erosion, wear rings
Check: Visual inspection for: erosion, pitting, cavitation damage, cracks, dents or irregularities on impeller blade leading edges and hub. Inspect wear rings (front/rear) for scratches/deformation. Measure clearance between impeller and pump housing with caliper. Decrease in flow rate/pressure build-up/current consumption indicates impeller damage.
Area: Motor - wear, bearing wear, heat development, contamination
Check: Motor to be inspected visually and cleaned regularly for adequate cooling. In dusty environments inspect more frequently. Monitor temperature (elevated heat development = early fault signal). Detect bearing wear through vibrations/noise. Compare current consumption vs. rated value. Motor bearings in 2/4/6-pole motors up to 11 kW are maintenance-free lubricated; larger motors to be lubricated regularly.
Area: Öl im Pumpenraum - Verschmutzung, Wassergehalt, Alterung
Check: Check oil level after 1 week of operation (after seal replacement). Monitor water content: >20% water means seal failure. Oil change every 3,000 operating hours or 1x/year (Shell Ondina 917 or similar). Inspect oil colour, odour, turbidity for contamination/combustion products.
Area: Corrosion in seawater applications - material degradation in corrosive environment
Check: For seawater/marine environments: pump must be designed in high-grade stainless steel (EN 1.4517 Duplex, AISI 316) or titanium. Perform visual inspection for surface rust, pittings, discoloration. High-grade stainless steel designs (EN 1.4408) for T>40°C and chemical fluids. Use special seals (Super Duplex) and sealants for aggressive media.

Check: Visual inspection: leakage quantity 1-10 ml/24h is normal. If >20% water content in oil chamber after 1 week of operation, seal is defective. Seal faces NOT to be touched with bare fingers. At standstill: inject silicone oil between pump housing and coupling to prevent face adhesion.
Area: Bearing (ball/roller bearing) - wear, bearing clearance, lubrication film breakdown
Check: Check circulation lubrication: relubricate SKF LGHP2 grease using grease gun. Measure bearing clearance with caliper per workshop guidelines. After 100,000 operating hours perform replacement. Motors up to 11 kW are permanently lubricated (no relubrication required). Abnormal vibrations/noise indicate bearing wear.
Area: Impeller - wear, cavitation, erosion, wear rings
Check: Visual inspection for: erosion, pitting, cavitation damage, cracks, dents or irregularities on impeller blade leading edges and hub. Inspect wear rings (front/rear) for scratches/deformation. Measure clearance between impeller and pump housing with caliper. Decrease in flow rate/pressure build-up/current consumption indicates impeller damage.
Area: Motor - wear, bearing wear, heat development, contamination
Check: Motor to be inspected visually and cleaned regularly for adequate cooling. In dusty environments inspect more frequently. Monitor temperature (elevated heat development = early fault signal). Detect bearing wear through vibrations/noise. Compare current consumption vs. rated value. Motor bearings in 2/4/6-pole motors up to 11 kW are maintenance-free lubricated; larger motors to be lubricated regularly.
Area: Öl im Pumpenraum - Verschmutzung, Wassergehalt, Alterung
Check: Check oil level after 1 week of operation (after seal replacement). Monitor water content: >20% water means seal failure. Oil change every 3,000 operating hours or 1x/year (Shell Ondina 917 or similar). Inspect oil colour, odour, turbidity for contamination/combustion products.
Area: Corrosion in seawater applications - material degradation in corrosive environment
Check: For seawater/marine environments: pump must be designed in high-grade stainless steel (EN 1.4517 Duplex, AISI 316) or titanium. Perform visual inspection for surface rust, pittings, discoloration. High-grade stainless steel designs (EN 1.4408) for T>40°C and chemical fluids. Use special seals (Super Duplex) and sealants for aggressive media.

Common Failures & Inspection Points

Area: Mechanical seal (mechanical face seal) - wear, leakage, surface roughness
Check: Visual inspection: leakage quantity 1-10 ml/24h is normal. If >20% water content in oil chamber after 1 week of operation, seal is defective. Seal faces NOT to be touched with bare fingers. At standstill: inject silicone oil between pump housing and coupling to prevent face adhesion.
Area: Bearing (ball/roller bearing) - wear, bearing clearance, lubrication film breakdown
Check: Check circulation lubrication: relubricate SKF LGHP2 grease using grease gun. Measure bearing clearance with caliper per workshop guidelines. After 100,000 operating hours perform replacement. Motors up to 11 kW are permanently lubricated (no relubrication required). Abnormal vibrations/noise indicate bearing wear.
Area: Impeller - wear, cavitation, erosion, wear rings
Check: Visual inspection for: erosion, pitting, cavitation damage, cracks, dents or irregularities on impeller blade leading edges and hub. Inspect wear rings (front/rear) for scratches/deformation. Measure clearance between impeller and pump housing with caliper. Decrease in flow rate/pressure build-up/current consumption indicates impeller damage.
Area: Motor - wear, bearing wear, heat development, contamination
Check: Motor to be inspected visually and cleaned regularly for adequate cooling. In dusty environments inspect more frequently. Monitor temperature (elevated heat development = early fault signal). Detect bearing wear through vibrations/noise. Compare current consumption vs. rated value.

Common Failures & Inspection Points

Area: Mechanical seal (mechanical face seal) - wear, leakage, surface roughness
Check: Visual inspection: leakage quantity 1-10 ml/24h is normal. If >20% water content in oil chamber after 1 week of operation, seal is defective. Seal faces NOT to be touched with bare fingers. At standstill: inject silicone oil between pump housing and coupling to prevent face adhesion.
Area: Bearing (ball/roller bearing) - wear, bearing clearance, lubrication film breakdown
Check: Check circulation lubrication: relubricate SKF LGHP2 grease using grease gun. Measure bearing clearance with caliper per workshop guidelines. After 100,000 operating hours perform replacement. Motors up to 11 kW are permanently lubricated (no relubrication required). Abnormal vibrations/noise indicate bearing wear.
Area: Impeller - wear, cavitation, erosion, wear rings
Check: Visual inspection for: erosion, pitting, cavitation damage, cracks, dents or irregularities on impeller blade leading edges and hub. Inspect wear rings (front/rear) for scratches/deformation. Measure clearance between impeller and pump housing with caliper. Decrease in flow rate/pressure build-up/current consumption indicates impeller damage.
Area: Motor - wear, bearing wear, heat development, contamination
Check: Motor to be inspected visually and cleaned regularly for adequate cooling. In dusty environments inspect more frequently. Monitor temperature (elevated heat development = early fault signal). Detect bearing wear through vibrations/noise. Compare current consumption vs. rated value. Motor bearings in 2/4/6-pole motors up to 11 kW are maintenance-free lubricated; larger motors to be lubricated regularly.
Area: Öl im Pumpenraum - Verschmutzung, Wassergehalt, Alterung
Check: Check oil level after 1 week of operation (after seal replacement). Monitor water content: >20% water means seal failure. Oil change every 3,000 operating hours or 1x/year (Shell Ondina 917 or similar). Inspect oil colour, odour, turbidity for contamination/combustion products.
Area: Corrosion in seawater applications - material degradation in corrosive environment
Check: For seawater/marine environments: pump must be designed in high-grade stainless steel (EN 1.4517 Duplex, AISI 316) or titanium. Perform visual inspection for surface rust, pittings, discoloration. High-grade stainless steel designs (EN 1.4408) for T>40°C and chemical fluids.

Common Failures & Inspection Points

Area: Mechanical seal (mechanical face seal) - wear, leakage, surface roughness
Check: Visual inspection: leakage quantity 1-10 ml/24h is normal. If >20% water content in oil chamber after 1 week of operation, seal is defective. Seal faces NOT to be touched with bare fingers. At standstill: inject silicone oil between pump housing and coupling to prevent face adhesion.
Area: Bearing (ball/roller bearing) - wear, bearing clearance, lubrication film breakdown
Check: Check circulation lubrication: relubricate SKF LGHP2 grease using grease gun. Measure bearing clearance with caliper per workshop guidelines. After 100,000 operating hours perform replacement. Motors up to 11 kW are permanently lubricated (no relubrication required). Abnormal vibrations/noise indicate bearing wear.
Area: Impeller - wear, cavitation, erosion, wear rings
Check: Visual inspection for: erosion, pitting, cavitation damage, cracks, dents or irregularities on impeller blade leading edges and hub. Inspect wear rings (front/rear) for scratches/deformation. Measure clearance between impeller and pump housing with caliper. Decrease in flow rate/pressure build-up/current consumption indicates impeller damage.
Area: Motor - wear, bearing wear, heat development, contamination
Check: Motor to be inspected visually and cleaned regularly for adequate cooling. In dusty environments inspect more frequently. Monitor temperature (elevated heat development = early fault signal). Detect bearing wear through vibrations/noise. Compare current consumption vs. rated value. Motor bearings in 2/4/6-pole motors up to 11 kW are maintenance-free lubricated; larger motors to be lubricated regularly.
Area: Öl im Pumpenraum - Verschmutzung, Wassergehalt, Alterung
Check: Check oil level after 1 week of operation (after seal replacement). Monitor water content: >20% water means seal failure. Oil change every 3,000 operating hours or 1x/year (Shell Ondina 917 or similar). Inspect oil colour, odour, turbidity for contamination/combustion products.
Area: Corrosion in seawater applications - material degradation in corrosive environment
Check: For seawater/marine environments: pump must be designed in high-grade stainless steel (EN 1.4517 Duplex, AISI 316) or titanium. Perform visual inspection for surface rust, pittings, discoloration. High-grade stainless steel designs (EN 1.4408) for T>40°C and chemical fluids. Use special seals (Super Duplex) and sealants for aggressive media.

Common Failures & Inspection Points

Area: Mechanical seal: leakage, wear of sealing surfaces, surface damage
Check: Visual inspection of seal housing and shaft for drip traces or moisture; pressure testing with manometer to detect pressure drops; soap solution for bubble formation and leak location; control of scavenge system for blockages (overheating causes premature wear). Monitor leak rate: mechanical seal normal <0.006 l/h
Area: Bearing: wear, temperature rise, faulty lubrication (oil/grease)
Check: Measure bearing temperature and compare with manufacturer specifications; check vibration and smooth running of pump and motor; check lubricant supply and exchange intervals; inspect elastic transmission elements (coupling bolts, discs, packages) for wear; control coupling alignment. Coupling replacement recommended in case of wear
Area: Impeller/wear rings: wear on running and suction side, contamination damage, surface corrosion
Check: Visual-mechanical inspection for wear of sealing rings and impeller wear protection; check for wear of shaft keyways and bearing seats; clearance inspection (<1 µm normal value for seals); check wear ring material (hard-chromed or nitrided for abrasive media >800-1000 HV surface hardness). Replace damaged or worn parts with genuine spare parts
Area: Cavitation: pressure drop below vapor pressure, bubble implosion, material erosion on housing and impeller
Check: Compare NPSH value of system (NPSHA) against required pump NPSH (NPSHR) from data sheet; NPSHA must be >= NPSHR over entire operating range; monitor pump smooth running and operating noise (cavitation noise = rough operating noise); perform pressure test bench tests to simulate cavitation conditions; check suction conditions and system design; visually inspect housing and impeller for pitting and surface erosion
Area: Systemkomponenten: Rohrleitungen, Armaturen, Schaltfunktion, elektronische Überwachung, Korrosion
Check: Inspect piping and fittings for wear, corrosion and functionality; test pump control and switching function; check electronic monitoring systems; inspect general housing corrosion and bearing contamination traces; perform surface cleaning (DO NOT flush, instead apply protective grease); document all inspection results

Common Failures & Inspection Points

Area: Mechanical seal: leakage, wear of sealing surfaces, surface damage
Check: Visual inspection of seal housing and shaft for drip traces or moisture; pressure testing with manometer to detect pressure drops; soap solution for bubble formation and leak location; control of scavenge system for blockages (overheating causes premature wear). Monitor leak rate: mechanical seal normal <0.006 l/h
Area: Bearing: wear, temperature rise, faulty lubrication (oil/grease)
Check: Measure bearing temperature and compare with manufacturer specifications; check vibration and smooth running of pump and motor; check lubricant supply and exchange intervals; inspect elastic transmission elements (coupling bolts, discs, packages) for wear; control coupling alignment. Coupling replacement recommended in case of wear
Area: Impeller/wear rings: wear on running and suction side, contamination damage, surface corrosion
Check: Visual-mechanical inspection for wear of sealing rings and impeller wear protection; check for wear of shaft keyways and bearing seats; clearance inspection (<1 µm normal value for seals); check wear ring material (hard-chromed or nitrided for abrasive media >800-1000 HV surface hardness). Replace damaged or worn parts with genuine spare parts
Area: Cavitation: pressure drop below vapor pressure, bubble implosion, material erosion on housing and impeller
Check: Compare NPSH value of system (NPSHA) against required pump NPSH (NPSHR) from data sheet; NPSHA must be >= NPSHR over entire operating range; monitor pump smooth running and operating noise (cavitation noise = rough operating noise); perform pressure test bench tests to simulate cavitation conditions; check suction conditions and system design; visually inspect housing and impeller for pitting and surface erosion

Common Failures & Inspection Points

Area: Mechanical seal: leakage, wear of sealing surfaces, surface damage
Check: Visual inspection of seal housing and shaft for drip traces or moisture; pressure testing with manometer to detect pressure drops; soap solution for bubble formation and leak location; control of scavenge system for blockages (overheating causes premature wear). Monitor leak rate: mechanical seal normal <0.006 l/h
Area: Bearing: wear, temperature rise, faulty lubrication (oil/grease)
Check: Measure bearing temperature and compare with manufacturer specifications; check vibration and smooth running of pump and motor; check lubricant supply and exchange intervals; inspect elastic transmission elements (coupling bolts, discs, packages) for wear; control coupling alignment. Coupling replacement recommended in case of wear
Area: Impeller/wear rings: wear on running and suction side, contamination damage, surface corrosion
Check: Visual-mechanical inspection for wear of sealing rings and impeller wear protection; check for wear of shaft keyways and bearing seats; clearance inspection (<1 µm normal value for seals); check wear ring material (hard-chromed or nitrided for abrasive media >800-1000 HV surface hardness). Replace damaged or worn parts with genuine spare parts
Area: Cavitation: pressure drop below vapor pressure, bubble implosion, material erosion on housing and impeller
Check: Compare NPSH value of system (NPSHA) against required pump NPSH (NPSHR) from data sheet; NPSHA must be >= NPSHR over entire operating range; monitor pump smooth running and operating noise (cavitation noise = rough operating noise); perform pressure test bench tests to simulate cavitation conditions; check suction conditions and system design; visually inspect housing and impeller for pitting and surface erosion
Area: Systemkomponenten: Rohrleitungen, Armaturen, Schaltfunktion, elektronische Überwachung, Korrosion
Check: Inspect piping and fittings for wear, corrosion and functionality; test pump control and switching function; check electronic monitoring systems; inspect general housing corrosion and bearing contamination traces; perform surface cleaning (DO NOT flush, instead apply protective grease); document all inspection results

Common Failures & Inspection Points

Cavitation caused by insufficient suction head, blocked strainers or excessive suction losses, resulting in crackling noise, vibration and reduced delivery
Mechanical-seal or gland leakage caused by wear, misalignment or damaged sealing faces, resulting in visible leakage around the shaft
Bearing deterioration caused by poor lubrication, contamination or misalignment, resulting in increased noise, vibration or bearing temperature
Impeller or casing erosion and fouling caused by abrasive solids, corrosion or deposits, resulting in reduced capacity and efficiency
Coupling or drive problems caused by misalignment, looseness or motor faults, resulting in vibration, abnormal current draw or failure to reach normal speed

Service: Inspect suction strainers, valves, seals, bearings, coupling alignment, foundation bolts and visible casing condition. Trend suction and discharge indications together with vibration, noise and motor load where available. Verify that the pump is properly vented or primed before operation and that no persistent air ingress is present on the suction side. Check for shaft leakage, abnormal bearing temperature and deterioration of flexible coupling elements. Inspect the impeller and casing when performance declines or internal damage is suspected. Refer to the manufacturer documentation for the exact clearances, alignment criteria and wear limits.

Spare Parts: Keep shaft-sealing components, bearings, coupling elements, casing or cover gaskets and the pump-specific wear parts recommended by the manufacturer. For critical service, an impeller or rotating assembly may be appropriate depending on redundancy and onboard repair capability. Confirm all parts against the exact pump model and serial number.

Verify pressure and flow indications are consistent with the vessel's established normal test results and investigate deterioration. Check remote starting and independent power or fuel arrangements where applicable. Inspect sea suction and strainers for blockage and corrosion. Refer to class, statutory and manufacturer documentation for exact test criteria and wear limits.

Spare Parts: Keep shaft-sealing parts, bearings, coupling elements, priming-system consumables, gaskets and drive or starting-system spares recommended for the installed unit. Emergency-pump spares should reflect its independent configuration. Confirm exact parts from the pump and driver serial numbers.

Use Cases: Fire-main supply on merchant ships, offshore units, passenger vessels and workboats fitted with main and/or emergency firefighting pumps.

Seal, packing or gasket wear causes visible leakage and falling system pressure
Bearing, shaft or coupling wear causes vibration, abnormal noise or rising temperature
Impeller, screw or other pumping-element wear or fouling reduces capacity and may increase drive load
Motor, hydraulic-drive, valve or control faults cause failure to start, reduced speed or protective trips

Spare Parts: Carry seals or packing, bearings where appropriate, coupling parts, gaskets, filters and critical hydraulic or electrical control spares for the installed pump type.

Strengths

Dual‑service design (main + emergency) in one unit, simplifying layout
Robust cast‑iron housing and double‑suction impeller for high reliability
Mechanical seal with easy access for routine inspection and replacement
Low vibration and noise levels, suitable for passenger‑ship accommodation spaces
Meets SOLAS fire‑pump testing requirements (weekly & quarterly full‑flow tests)

Weaknesses

Relatively heavy and bulky compared with modern compact electric units
Impeller erosion can occur if suction strainer fouling is not tightly controlled
Mechanical seal life limited; requires scheduled replacement to avoid failure
Fixed‑speed operation limits flow fine‑tuning versus variable‑speed drives
Higher upfront cost than some competing single‑service pumps

Typical Vessels: Passenger shipCruise linerRo‑Ro ferryContainer vesselTankerOffshore supply vessel

Decision Guide: Choose if you need a proven, SOLAS‑compliant fire pump that can serve both main and emergency functions in one compact package and you have space for a cast‑iron unit. Avoid if vessel weight or space constraints are critical, or if you prefer a variable‑speed, lightweight electric pump with lower initial cost.

Use Cases: Cooling, ballast, bilge, fire, fuel, lubricating-oil, cargo and general liquid-transfer duties.

Diesel engine start failures may occur in cold weather or after long idle periods
Fixed flow rating limits use on very large tankers that require higher fire‑water capacity
Dependence on diesel fuel means additional fuel management compared with electric fire pumps

Typical Vessels: Oil tankerChemical tankerBulk carrierContainer ship (mid‑size)Offshore supply vessel

Decision Guide: Choose if you need a space‑saving, dual‑function fire pump with proven diesel reliability and can accommodate its flow rating. Avoid if the vessel requires higher fire‑water capacity than an 80 kW unit provides, or if you prefer an electric fire pump to eliminate fuel‑related start issues.

Use Cases: Cooling, ballast, bilge, fire, fuel, lubricating-oil, cargo and general liquid-transfer duties.
