Jerky controls, stiff joysticks, or loss of pilot-operated functions — a failing pilot pump is often the first sign your Kato 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 Kato HD series lineup.
Why Choose Our Kato 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.
Provide our parts team with your Kato machine serial number or the stamped data code on your current pump housing, and we'll ship the exact replacement you need.
