How often should pumps be serviced?
Most hydrostatic pumps should be inspected at least once a year under normal operating conditions, or every 1,000–2,000 operating hours. Heavy-duty applications in construction, agriculture, or material handling may require more frequent servicing. Regular maintenance—including fluid checks, seal inspections, and pressure testing—prevents minor wear from escalating into costly failures and extends the pump's operational lifespan significantly.
What are common pump problems?
Common hydrostatic pump problems include internal leakage due to worn seals or O-rings, reduced pressure or flow output, unusual noise or vibration caused by cavitation or bearing wear, overheating from contaminated hydraulic fluid, and slow or erratic operation. Many of these issues stem from deferred maintenance. Early diagnosis through pressure and flow testing can identify the root cause before complete pump failure occurs.
What brands of hydrostatic pumps do you rebuild?
We rebuild pumps and motors from virtually all major manufacturers, including Rexroth, Parker, Kawasaki, Eaton, Vickers, Danfoss, Sundstrand, Uchida, Komatsu, Hydromatik, Brueninghaus, Cessna, Hitachi, Linde, Volvo, John Deere, Sauer Danfoss, Mitsubishi, and many more. Every unit is rebuilt to original manufacturer specifications and covered by a 1-year warranty.
What does the pump rebuild process include?
Our rebuild process covers complete disassembly, pressure washing, solvent cleaning in a reduced-dust environment, full component measurement against manufacturer specs, valve and manifold rebuild, replacement of all seals, gaskets, and O-rings, leak testing, pressure and flow calibration, oil fill for shipping protection, and a fresh paint finish. Every completed unit is issued a 1-year warranty before dispatch.
Do you offer a pump exchange program?
Yes. Our Short-Time Exchange Program allows customers to receive a quality-tested, warranted rebuilt replacement unit shipped quickly to minimize equipment downtime. We exchange drives, pumps, and motors for all major brands including Kawasaki, Eaton, Rexroth, Vickers, Sundstrand, Komatsu, and more. Every exchanged unit is fully warranted and quality-assured before shipment.
What warranty do you provide on rebuilt pumps and motors?
All rebuilt and exchanged hydrostatic pumps, motors, and drives carry a 1-year warranty. This applies to every unit we rebuild or provide through our exchange program, regardless of brand. Our warranty reflects the confidence we have in our rebuild process, our technicians' workmanship, and our commitment to meeting or exceeding original manufacturer quality standards.
Can you supply replacement parts for hydrostatic pumps?
Yes. We supply new, used, and hard-to-find hydrostatic and hydraulic parts internationally for brands including Parker, Eaton, Rexroth, Kawasaki, Danfoss, Vickers, Cessna, Hydromatik, Brueninghaus, Uchida, and Sundstrand. Whether you need a single seal kit or a complete set of displacement valves, our parts inventory is designed to support fast turnaround and reduce equipment downtime.
Do you provide installation advice for hydrostatic pumps and drives?
Yes. Our trained technicians offer an installation advice service to help customers correctly install and maintain their rebuilt hydrostatic drive, pump, or motor. Proper installation is critical to unit longevity and performance. Our technicians draw on over 100 years of combined experience to provide practical, accurate guidance tailored to your specific equipment and application requirements.
