IHS specializes in hydraulic pump and motor service. We have a large selection of gear pumps on the shelf, ready to replace your old unit. We also stock a large selection of repair parts for quick turn-around when needed. We tear down and rebuild piston pumps, motors, and hydrostats on a regular basis. We will diagnose the cause of failure, and quote a repair or replacement as needed. See our pump tech info page for installation checklists and specifications.
