Frequently Asked Questions

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.
