Why Hydraulic Pump Failure is Critical for Clamshell Grabs

The hydraulic pump is the heart of every modern Clamshell Grab. When it fails, the grab cannot close properly, dramatically reducing discharging rates and causing expensive delays. Fast, professional Marine services are essential to get the grab back into full operation. VietNam Shiprepair’s riding teams carry stock pumps (Parker, Rexroth, Kawasaki, and OEM Chinese) and can mobilise within hours.

Step-by-Step Hydraulic Pump Replacement Process

Our experienced technicians follow this proven procedure:

1. Safe positioning of the grab on deck with wooden supports

2. Full depressurisation and isolation of the hydraulic system

3. Removal of high-pressure hoses and mounting bolts

4. Careful extraction of the old pump (120–180 kg) using a deck crane

5. Installation of the new, class-approved hydraulic pump with correct torque settings

6. Replacement of all seals and O-rings

7. Refilling with fresh ISO VG46 hydraulic oil and complete air bleeding

8. Pressure testing (180–220 bar working, 280 bar max)

9. No-load and full-load function tests (1.5 × SWL)

10. Final handover with class surveyor attendance (DNV/NK/ABS) if required

The entire job is normally completed within 6–10 hours by a 4–5 man team.
