Samsung Main Pump Parts

When a main hydraulic pump loses pressure, the housing is often still perfectly serviceable. The real culprits are worn internal components — rotating groups, valve plates, and cylinder barrels that have simply reached their service limit. Replacing key internals is a highly cost-effective way to restore your Samsung excavator's hydraulic performance without the cost of a complete pump.

We supply a comprehensive range of precision-engineered internal components for main pumps used across the Samsung SE / MX series lineup — including SE Series (SE50 through SE450), MX Series (MX135WS through MX295) and current generation models.

We stock direct-fit pump configurations for the full Samsung lineup.
