Develon / Doosan 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 Develon / Doosan 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 Develon / Doosan DX / DH / Solar series lineup — including Daewoo Solar Series (legacy),  DX-3/DX-5/DX-7 Series and current generation models.

We stock direct-fit pump configurations for the full Develon / Doosan lineup.
