Closed circuit high power pumps & motors

Our closed circuit high power pumps & motors
 

Pass the most challenging test with our high power pumps and motors – for the toughest demands of the off-highway mobile market.

The answer to your high power propulsion and heavy work function needs is in our hands. Our PLUS+1®   Compliant closed circuit axial piston variable pumps, fixed and variable motors, and variable displacement bent axis motors are designed for just that job. Bring together a pump, motor and a PLUS+1 microcontroller in a closed circuit sub-system, and enjoy the benefits of a super smart drive.

Our H1 pumps feature common design technologies and assembly techniques. Overall, they offer simpler, high performance designs with fewer parts than previous hydrostatic products. Designed for smaller package sizes, our pumps provide design engineers with more freedom and flexibility in system design.
