Frequently Asked Questions

Can a pump be repaired?

Yes — most hydrostatic and hydraulic pumps can be fully rebuilt rather than replaced. Our process involves disassembly, precision measurement, reconditioning or replacing worn components, reassembly with new seals and O-rings, and rigorous pressure and flow testing. Rebuilding typically costs significantly less than purchasing a new unit and every rebuild we perform is backed by a 1-year warranty.
