Cargo Pump (Centrifugal, Pumproom)

critical IMO Required 25 / 25 models (Inspector)

A pumproom-mounted centrifugal cargo pump keeps its driver -- steam turbine or electric motor -- outside the hazardous space, coupled to the impeller through a long vertical line shaft that crosses the pumproom bulkhead through a sealed gland.

What sets this pump apart

A pumproom centrifugal cargo pump is driven from outside the hazardous space: the impeller sits low in the pumproom, but the steam turbine or electric motor that turns it sits in the engine room, connected through a long vertical shaft that passes through a gas-tight bulkhead gland. That single arrangement separates it from a deepwell pump, where the motor rides on top of the column inside the tank, and from a submersible pump, where the whole unit is immersed in the cargo. The bulkhead penetration gives easier maintenance access to the driver but adds one more sealing point that can pass vapour into the engine room if it is neglected.

Pumproom centrifugal cargo pump
Vertical section of a pumproom-mounted centrifugal cargo pump showing the deck-mounted driver, the long line shaft crossing a gastight deck seal, the pump casing with impeller, the suction bellmouth from the tank and the discharge to the cargo line.

Main components

Casing and impeller

Single or multi-stage centrifugal casing, usually duplex or austenitic stainless steel for corrosive or aggressive cargoes, carbon steel with a protective coating for cleaner products. Impeller trim (diameter and vane profile) sets the duty point on the pump curve.

Vertical line shaft and bearings

A long shaft, supported by intermediate line shaft bearings, connects the driver to the pump. Bearings are usually product- or water-lubricated and are the first place misalignment shows up as vibration.

Bulkhead gland

The seal where the shaft crosses from pumproom to engine room, either a mechanical seal or a packed gland. This is a designated gas-hazard boundary and is monitored accordingly.

Driver

Steam turbine, common on older and larger tankers because it needs no electrical certification in the pumproom, or a variable-speed electric motor located in a non-hazardous area, coupled through the same vertical shaft.

Suction bell and strum box

Strainer at the tank suction that keeps debris and scale out of the impeller. Stripping arrangements, eductors or a dedicated stripping pump, handle the last cargo the main pump cannot lift once suction breaks.

Selection and sizing

Sizing runs off capacity, typically several hundred to well over a thousand cubic metres per hour per pump on a product or crude tanker, total developed head against manifold back-pressure and shore line resistance, and NPSH available at minimum tank level versus NPSH required by the pump. That last figure usually limits how far a tank can be stripped by the main pump before switching to eductors. Cargo viscosity and vapour pressure at loading temperature also set limits: a viscous or high-vapour-pressure cargo needs a flatter curve and more NPSH margin than the pump's water-test curve suggests. Most tankers fit one pump per cargo tank group so segregated grades can be discharged in parallel.

Regulations and class

The pumproom is a hazardous space under SOLAS Ch. II-2 and, where applicable, the IBC Code, with mechanical ventilation running continuously in port and gas detection at the entrance and at the bulkhead gland. Class rules require periodic survey of the shaft seal and bearings, and the bulkhead penetration is a specific item on annual and special survey checklists. Electric motor drivers in the engine room must still satisfy the certification appropriate to their proximity to the hazardous boundary.

Typical faults

  • Bulkhead gland wear -- loses its seal over time; the consequence is vapour migration into the engine room, which is why gas detection sits right at that point.
  • Cavitation from insufficient NPSH -- usually from stripping too low a tank level or a blocked strum box; the consequence is impeller and casing erosion and a sharp drop in delivered capacity.
  • Line shaft misalignment -- from bearing wear or a shifted foundation; the consequence is vibration that accelerates bearing failure and can eventually crack the shaft.
  • Impeller wear from abrasive or corrosive cargo -- the consequence is falling head and capacity even though the pump still runs smoothly.

What to look for in a supplier

  • Casing and impeller material actually matched to the cargo slate the vessel trades, not a generic stainless specification.
  • A bulkhead seal design with a proven service record and accessible spares.
  • Documented pump curves at the viscosities and temperatures the vessel actually loads, not only water curves.
  • Line shaft bearing spares available without a long lead time, since a bearing failure can take a pump out of service mid-voyage.

Treat the bulkhead gland like a class item every voyage, not only at survey -- a slow vapour leak there is one of the few cargo pump faults that turns into a safety case rather than a maintenance job.

Common Failures & Inspection Points
  • Bearing, shaft or guide wear causes vibration, abnormal noise, reduced efficiency or mechanical contact
  • Tank-top, shaft or mechanical seal leakage causes visible cargo leakage, vapour release or contamination of adjacent systems
  • Hydraulic, electric or mechanical drive faults cause reduced speed, inability to start or protective trips
  • Impeller or pump-stage fouling, erosion or damage causes low discharge pressure and reduced cargo rate
  • Dry running, poor suction or inadequate tank level causes overheating, vibration or accelerated wear
Service: Inspect seals, drive system, bearings, shaft condition where accessible, vibration, discharge behaviour and leakage. Confirm stripping and minimum-liquid operating practices follow the approved cargo procedure. Review hydraulic oil, motor or gearbox condition as applicable. Refer to the manufacturer documentation for the exact figure for clearances, minimum levels and wear limits.
Spare Parts: Carry seal kits, bearings or bushings where approved for onboard work, hydraulic or electrical drive spares, gaskets and critical pump-stage components identified by the manufacturer.
Strengths

Common Failures & Inspection Points
  • Loss of suction or cavitation caused by low inlet head, blocked strainers, closed valves or air ingress can produce noise, vibration and reduced delivery
  • Seal or gasket deterioration caused by wear, temperature or chemical attack can produce visible leakage or loss of prime
  • Bearing, shaft or coupling wear caused by misalignment, poor lubrication or prolonged vibration can show as rising noise, temperature or vibration
  • Impeller, screw, rotor or internal pumping-element wear caused by solids, corrosion or abrasive service can result in reduced capacity and longer transfer times
  • Driver or control faults caused by motor, hydraulic, protection or instrumentation problems can cause failure to start, trips or unstable speed
Service: Inspect for leakage, vibration, abnormal noise, bearing condition, coupling alignment, seal condition and secure foundations. Check suction strainers, valves and piping for restrictions or air ingress and confirm that instruments and protection devices respond correctly. Compare operating condition with the maker's documentation and vessel records; refer to manufacturer documentation for exact clearances and wear limits.

600 m³/h at 140 mLC · Marine Equipment · Centrifugal Pump
Common Failures & Inspection Points
  • Bearing, shaft or guide wear causes vibration, abnormal noise, reduced efficiency or mechanical contact
  • Tank-top, shaft or mechanical seal leakage causes visible cargo leakage, vapour release or contamination of adjacent systems
  • Hydraulic, electric or mechanical drive faults cause reduced speed, inability to start or protective trips
  • Impeller or pump-stage fouling, erosion or damage causes low discharge pressure and reduced cargo rate
  • Dry running, poor suction or inadequate tank level causes overheating, vibration or accelerated wear
Service: Inspect seals, drive system, bearings, shaft condition where accessible, vibration, discharge behaviour and leakage. Confirm stripping and minimum-liquid operating practices follow the approved cargo procedure. Review hydraulic oil, motor or gearbox condition as applicable. Refer to the manufacturer documentation for the exact figure for clearances, minimum levels and wear limits.
Spare Parts: Carry seal kits, bearings or bushings where approved for onboard work, hydraulic or electrical drive spares, gaskets and critical pump-stage components identified by the manufacturer.
Strengths
