Jerky controls, stiff joysticks, or loss of pilot-operated functions — a failing pilot pump is often the first sign your Develon / Doosan excavator's hydraulic control circuit is under pressure. We supply premium-grade, direct-replacement gear-type pilot pumps and charge pumps engineered specifically for the Develon / Doosan DX / DH / Solar series lineup.
Why Choose Our Develon / Doosan Replacement Pilot Pumps?
- Direct Flange Mounting: Engineered to exact OEM dimensions to bolt directly onto the rear of your main piston pump assembly — no modifications, no adaptors.
- Fully Assembled and Tested: Every pilot pump arrives pre-assembled and factory pressure-tested, ready for rapid installation to minimise machine downtime.
- Seal Kits Available: If you only need to stop a leak between the main pump and pilot unit, we also stock the appropriate O-ring and seal kits.
The pilot pump is almost always physically attached to the rear of the main tandem pump assembly. We offer exact-fit units matching both Develon / Doosan part numbers and original manufacturer specifications.
Provide our parts team with your Develon / Doosan machine serial number or the stamped data code on your current pump housing, and we'll ship the exact replacement you need.
