Marine Pump Spares & Mechanical Seals
Marine pump spare parts and mechanical seals supplied worldwide — seal assemblies and faces, impellers, wear rings, shaft sleeves, bearings and gasket kits for cargo, ballast, bilge, fire, cooling and fuel transfer pumps.
Marine pump spare parts are the most requested items we handle, and the mechanical seal is almost always the reason. A seal is a consumable running against a shaft at close tolerance: the faces wear, the elastomers harden, and the first sign is a drip that becomes a leak-off alarm. Replacing it is routine — sourcing the right one is not, because seal face material, balance ratio and shaft diameter all have to match the pump build rather than the model name alone.
We supply seals and the wear parts around them for the makes that actually sail: Shinko, Teikoku, Naniwa, Taiko Kikai, Ishi and Shin Shin on Japanese and Korean tonnage, Framo submersible cargo pumps, and Allweiler, Desmi, Azcue, IMO, Kral, Hamworthy and Pompe Garbarino on European-built vessels. Quote against the pump nameplate and the seal part number and we come back with genuine and class-approved options together.
What We Supply
- Mechanical seal assemblies, cartridge seals and individual seal faces
- Seal faces in carbon, silicon carbide and tungsten carbide, with the correct elastomer grade
- Impellers, wear rings and casing rings
- Shaft sleeves, shafts and coupling elements
- Pump bearings, bearing housings and bearing covers
- Gasket sets, O-rings and complete seal kits by pump model
- Framo submersible cargo pump spares including cofferdam seals
- Complete replacement pump units where the casing is beyond repair
When a Pump Seal or Wear Part Needs Replacing
- Leak-off from the seal drain increasing, or a seal leakage alarm
- Loss of suction or falling discharge pressure at unchanged speed — usually wear ring clearance opened up
- Vibration traced to the pump rather than the driver, pointing at bearings or an unbalanced impeller
- Impeller vane erosion or cavitation pitting found at open-up
- Shaft sleeve scored where the seal runs, which will destroy a new seal within hours if reused
- Bearing temperature rising, or metallic particles in the bearing housing oil
- Cargo pump cofferdam filling on a Framo installation, indicating a failed seal
- Repeated seal failure — nearly always shaft run-out or a sleeve that was not renewed with the seal
Engine & Equipment Makes We Cover
Marine Pump Spares & Mechanical Seals supplied for the makes below, as genuine OEM and as class-approved equivalents — both quoted so you can decide against your survey date rather than guess.
What to Send Us for a Quote
Send the pump make and model from the nameplate, the serial number, and the seal part number if you have it. Also the shaft diameter and the duty — sea water, fresh water, fuel oil or cargo — because seal face and elastomer grade depend on the fluid, not on the pump model. If a seal has failed twice, tell us: that is usually shaft run-out or a sleeve that was not renewed, and a third seal will fail too.

Marine Pump Spares & Mechanical Seals — Common Questions
What superintendents and purchasing teams ask us most about marine pump spares and mechanical seals.
Which marine pump brands do you supply spare parts for?
Shinko, Teikoku, Naniwa, Taiko Kikai, Ishi and Shin Shin, plus Framo submersible cargo pumps and the European ranges — Allweiler, Desmi, Azcue, IMO, Kral, Hamworthy and Pompe Garbarino.
Can you supply a mechanical seal by pump model and part number?
Yes. Send the pump make, model and serial number with the seal part number. If you only have the pump plate, we can usually identify the seal from that plus the shaft diameter and the duty the pump is on.
What information decides which mechanical seal is correct?
Shaft diameter, seal face material, elastomer grade and balance ratio. Face material and elastomer depend on the fluid — sea water, fresh water, fuel oil or cargo — not on the pump model, which is why two identical pumps on different duties can take different seals.
My mechanical seal keeps failing. Why?
Almost always shaft run-out, or a shaft sleeve that was scored and not renewed when the seal was changed. A new seal running on a worn sleeve can fail within hours. Check run-out and renew the sleeve with the seal rather than fitting a third seal.
Do you supply Framo cargo pump spares?
Yes, including cofferdam seals and the associated wear parts. A cofferdam filling is the standard indication of a failed seal on a Framo installation and should not be left running.
Do pump spares come with class documentation?
Yes. Certificates of conformity and material traceability accepted by ABS, DNV, LR, BV, RINA, NK, KR and CCS, prepared before dispatch.
