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 Hidromek 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 Hidromek HMK series lineup — including HMK 62 Series (mini), HMK 140/145 and current generation models.
We stock direct-fit pump configurations for the full Hidromek lineup.
