Hydra Service offers an extensive inventory of Dynapower hydrostatic pumps, motors, parts, and service options.

Hydra Service is the only Dynapower OEM supplier. We manufacture new Generation II Dynapower units in addition to many parts for repair of older Phase III and Phase IV designs. Hydra service focuses on new hydrostatic starters, pumps, motors and parts for repair, and also offer factory repairs with rapid turnarounds to maximize uptime. 

At one point, Dynapower was the largest manufacturer of hydrostatic transmissions (axial piston pumps and motors) and was headquartered in Watertown, NY. In the early 90’s, Dynapower was purchased by Vickers and then by Eaton Hydraulics (now Danfoss). The ownership changes caused issues for the industry, but Hydra Service continues to reliably supply Dynapower products, repair Dynapower hydraulics, and provide Dynapower parts and service.
