Raymond Lift Pump – RA500-351

This hydraulic lift pump is built by Raymond for Raymond lift trucks and supplies the pressurized hydraulic flow that powers the truck's lift function. Every time the operator raises a load, this pump is what pressurizes the hydraulic circuit that drives the lift cylinder, making it one of the components most directly tied to how quickly and smoothly the mast responds to the lift control.

Hydraulic pumps of this type wear internally as their gears, vanes, or pistons cycle under pressure across thousands of lift operations, and as internal clearances open up from that wear, pump output drops even though the motor driving it is running normally. That shows up on the truck as a lift function that has slowed down or that struggles to reach full height under a loaded fork, a sign the pump is no longer delivering its rated flow.

At 8.9 pounds, this pump is sized for a mid-duty hydraulic circuit rather than a heavy counterbalanced truck's primary lift system. Ordering against the manufacturer part number ensures the replacement pump matches the mounting and flow characteristics of the original unit on the Raymond truck it services.
