Screw Pump

A screw pump moves fuel and lube oil with meshing helical rotors instead of gears or vanes, giving a smooth, low-pulsation flow that tolerates the viscosity swings of heavy fuel far better than a gear pump of the same duty.

What sets a screw pump apart

A screw pump is a positive displacement pump that moves liquid axially along meshing helical rotors (typically one power rotor driving one or two idler rotors) instead of trapping it between gear teeth or sliding vanes. The rotor geometry gives an almost pulsation-free, continuous flow, which matters for fuel injection supply and transfer duties where pressure spikes cause noise and wear elsewhere in the system. Compared with a gear pump, a screw pump tolerates a wider viscosity range with less efficiency loss, which is why it is the standard choice for heavy fuel oil (HFO) transfer and supply, where viscosity can swing several hundred centistokes between a cold start and normal running temperature. Screw pumps also run quieter and with less shaft vibration than gear or vane types at the same flow and pressure, an advantage in engine rooms with pumps mounted close to accommodation spaces.

Main components

Power rotor and idler rotor(s)

The power rotor is driven directly by the motor; idler rotors mesh with it and are turned only by the fluid film and rotor contact, not by a separate gear train in most designs, which keeps the pump simple and reduces parts subject to wear.

Housing / stator

Precision-bored housing that the rotors run in with close clearance; this clearance is what determines volumetric efficiency and how much internal slip, and therefore capacity loss, occurs at a given viscosity.

Mechanical seal or packed gland

Seals the shaft where it passes through the housing; mechanical seals dominate on modern fuel and lube oil screw pumps for tighter leak control.

Relief valve

Fitted internally or on the discharge line, since a positive displacement pump will build pressure indefinitely against a closed valve and must have a path to relieve it.

Selection and sizing

  • Viscosity range - the single most important selection parameter for fuel duty; the pump must maintain rated flow across the full range from cold-start to operating temperature.
  • Differential pressure - fuel supply pumps typically run at several bar; boosting or circulating pumps in HFO systems can run higher against injection system back-pressure.
  • NPSH available - suction conditions from the service tank, especially on transfer duty pulling from a nearly empty tank.
  • Rotor material and clearance - tighter clearances raise volumetric efficiency but reduce tolerance to solids or wear debris in the fluid.

Regulations and class

Fuel oil supply and transfer pumps fall under the classification society's machinery rules for essential auxiliary systems, which typically require duplication of fuel supply pumps to the main engine so a single pump failure does not stop propulsion. Class also reviews the relief valve setting and pressure rating of the pump and its piping as part of the fuel system approval. There is no IMO instrument specific to screw pumps; requirements apply to the fuel and lube oil systems they serve, under MARPOL Annex I for oil-handling arrangements and under class rules for redundancy of essential services.

Typical faults

FaultConsequence
Rotor and housing wear (increased clearance)falling volumetric efficiency, especially noticeable on light, low-viscosity fuel
Mechanical seal failurefuel or oil leakage at the shaft, a fire and slip hazard in the engine room
Relief valve stuck or incorrectly seteither nuisance recirculation losing capacity, or overpressure of piping if stuck shut
Cavitation on suctionnoise, rotor pitting and falling output, usually from a restricted suction line or a nearly empty tank

What to look for in a supplier

  • Published performance curves across the actual viscosity range the fuel or oil will see in service, not just at a single reference viscosity.
  • Rotor and housing material suited to the fluid, including compatibility with low-sulphur and biofuel blends now common in fuel systems.
  • Spare rotor sets and seal kits genuinely available for the model, since screw pump rotors are precision parts not produced by third parties.

A screw pump that loses capacity is almost always wear, not a blockage - rising slip through worn rotor clearance shows up first as reduced flow at normal running temperature, well before any alarm trips.

Common Failures & Inspection Points
  • Internal screw or liner wear caused by abrasive contamination or prolonged service, resulting in reduced capacity and increased internal leakage
  • Dry running or poor inlet supply caused by empty tanks, closed valves or suction restriction, resulting in abnormal noise, rapid heating or seizure risk
  • Shaft-seal leakage caused by worn sealing faces or misalignment, resulting in visible oil or fuel leakage
  • Bearing or timing-component deterioration caused by contamination, misalignment or lubrication problems, resulting in vibration and abnormal mechanical noise
  • Relief-valve malfunction caused by deposits, incorrect setting or mechanical sticking, resulting in abnormal discharge pressure or inability to protect the pump
Service: Check suction strainers, inlet conditions, shaft seals, bearings, drive coupling and relief arrangements. Monitor discharge pressure, noise, vibration and delivery for signs of internal wear or suction starvation. Avoid running the pump dry and verify that heating arrangements for viscous fluids are functioning where fitted. Inspect for external leakage and confirm that the handled fluid remains within the viscosity range intended for the installed pump. During overhaul, inspect screws, liners and bearings for scoring or contact. Refer to the manufacturer documentation for the exact clearances, relief settings and wear limits.
Spare Parts: Keep shaft seals, bearings, gaskets, coupling elements and relief-valve service parts appropriate to the installed model. For critical fuel or lubricating-oil service, manufacturer-recommended rotating or screw-set spares may be justified. Verify exact compatibility by model and serial number.
Use Cases: Fuel-oil transfer and supply, lubricating-oil circulation and other clean or moderately contaminated viscous-liquid duties on marine and offshore installations.

  • Loss of suction from empty source tank, closed valve, blocked strainer, air ingress, or poor priming causes low discharge pressure, cavitation noise, or no flow
  • Seal or packing wear caused by ageing, dry running, shaft movement, or contamination produces visible leakage or loss of suction
  • Bearing, coupling, gear, rotor, screw, impeller, or stator wear from poor lubrication, misalignment, debris, or normal service causes vibration, noise, heat, or reduced capacity
  • Internal wear, erosion, or excessive clearances caused by abrasive or corrosive media reduces discharge pressure and increases recirculation or running time
  • Motor, hydraulic drive, protection, or control faults caused by overload, electrical failure, or actuator problems result in trips, failed starting, or unstable speed
Service: Check suction and discharge conditions, strainers, leakage, seal area, bearings, vibration, noise, coupling alignment, driver load, valve lineup, and delivered performance. Inspect internal clearances or wear parts only to maker procedures; refer to manufacturer documentation for exact limits and settings.
Spare Parts: Typical spares include shaft seals or packing, O-rings and gaskets, bearings, coupling elements, wear rings or internal wear parts appropriate to the pump principle, and critical driver or control items recommended by the manufacturer.
Use Cases: Used across merchant, offshore, passenger, fishing, tug, and workboat systems for ballast, bilge, cooling, fuel, lubrication, cargo, fire, freshwater, sewage, and other liquid-transfer duties according to the specific pump type.

Common Failures & Inspection Points
  • Internal screw or liner wear caused by abrasive contamination or prolonged service, resulting in reduced capacity and increased internal leakage
  • Dry running or poor inlet supply caused by empty tanks, closed valves or suction restriction, resulting in abnormal noise, rapid heating or seizure risk
  • Shaft-seal leakage caused by worn sealing faces or misalignment, resulting in visible oil or fuel leakage
  • Bearing or timing-component deterioration caused by contamination, misalignment or lubrication problems, resulting in vibration and abnormal mechanical noise
  • Relief-valve malfunction caused by deposits, incorrect adjustment or sticking, resulting in abnormal discharge pressure or inability to protect the pump
Service: Check suction strainers, inlet conditions, shaft seals, bearings, drive coupling and relief arrangements. Monitor discharge pressure, noise, vibration and delivery for signs of internal wear or suction starvation. Avoid running the pump dry and verify heating arrangements for viscous fluids where fitted. Inspect for external leakage and confirm the handled fluid is suitable for the installed pump. During overhaul, inspect screws, liners and bearings for scoring or contact. Refer to the manufacturer documentation for exact clearances, relief settings and wear limits.
Spare Parts: Keep shaft seals, bearings, gaskets, coupling elements and relief-valve service parts appropriate to the installed model. For critical fuel or lubricating-oil service, manufacturer-recommended rotating or screw-set spares may be justified. Verify exact compatibility by model and serial number.

  • Self‑priming capability eliminates the need for external priming equipment
  • Robust Kracht brand reputation for marine service reliability
  • Straightforward maintenance – shaft seals are replaced on a defined 8,000 hr interval
  • Adequate flow rates for auxiliary and main fuel oil supply on medium‑sized vessels
Weaknesses
  • Gear tooth wear can lead to reduced efficiency and requires periodic inspection
  • Cavitation risk when pumping high‑viscosity fuels or at low NPSH conditions
  • Relief valve may malfunction if not regularly tested, potentially causing over‑pressure
  • Limited maximum flow compared with larger centrifugal fuel pumps
  • Sensitive to improper seal installation – leakage can develop before the 8,000 hr interval
Typical Vessels: Product tankerChemical tankerOffshore supply vesselMedium‑size container shipCruise ship auxiliary systems
Decision Guide: Choose if you need a reliable, low‑power fuel oil pump with self‑priming ability for medium‑viscosity fuels and have regular maintenance intervals available. Avoid if the installation requires very high flow rates, will operate with high‑viscosity or contaminated fuel, or cannot guarantee periodic seal and relief‑valve checks.
Use Cases: Cooling, ballast, bilge, fire, fuel, lubricating-oil, cargo and general liquid-transfer duties.

Common Failures & Inspection Points
  • Poor suction conditions, blockage or air ingress cause low flow, cavitation-like noise or unstable discharge
  • 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
Service: Inspect suction condition, strainers, seals, bearings, coupling or drive, foundation, leakage and associated valves. Trend pressure, flow, vibration and drive load where available. Investigate cavitation, abnormal noise or recurring trips promptly. Refer to the manufacturer documentation for the exact figure for clearances, wear limits and pressure settings.
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
  • Low power consumption (7.5 kW) suitable for auxiliary service
  • Compact design fits tight engine room spaces
  • Straightforward overhaul procedures – gear backlash check and seal replacement intervals are well defined
  • Kracht reputation for robust construction in marine environments
Weaknesses
  • Gear wear accelerates if oil is not properly filtered
  • Bearing failures reported when operating beyond design temperature limits
  • Shaft seal leakage requires replacement every ~12 000 h
  • Limited pressure capability compared with larger screw‑type pumps
Typical Vessels: TankerContainer shipBulk carrierOffshore supply vesselGeneral cargo vessel
Decision Guide: Choose if: you need a small, low‑power lube oil pump for main engine or gearbox lubrication and can maintain strict oil filtration and seal replacement schedules. Avoid if: high pressure or contamination‑tolerant pumping is required, or if longer seal intervals are critical.
Use Cases: Cooling, ballast, bilge, fire, fuel, lubricating-oil, cargo and general liquid-transfer duties.
