Hydraulic Pump Parts for Marine and Offshore Equipment

On a vessel the parts have to be right the first time. There is no second delivery once the ship has sailed, and a winch that will not hold is a safety matter, not a productivity one. Marine customers order by model code, order spares alongside the repair parts, and expect the box to arrive sealed and correct.

Marine and Offshore hydraulic pump parts from SEIMT Hydraulics

Industry Pain Points

  • The vessel sails on a fixed date and there is no room to wait for a second delivery
  • Salt air and long idle periods leave parts corroded before they are fitted
  • Deck machinery runs intermittently at high load, which is hard on rings and shoes
  • Older vessels carry equipment the original maker no longer supports

What Customers In This Sector Need

  • Correct identification from the model code before anything ships
  • Parts sealed against corrosion for long storage on board
  • Spares supplied with the repair parts so the ship carries a backup
  • Documentation that satisfies a class or owner inspection

Frequently Asked Questions

Can you deliver to a vessel in port?
Yes, through your agent or ship chandler. Give us the port and the date window.
How are parts protected for storage on board?
Oiled and vacuum sealed. Left sealed, they keep well in a damp store.
Do you supply spares alongside the repair parts?
Yes, and most marine customers order a spare ring set or seal kit with every repair.
What documents can you provide?
Material certificates, hardness reports, dimensional reports and packing photographs.
Are older frames still available?
Yes. Older marine equipment is one of the main reasons customers come to us.
