Variable pumps for open circuit

313 series

Open circuit variable displacement axial piston bent-axis hydraulic pumps



Purpose:
The pumps transform the shaft rotation mechanical energy into the working fluid flow hydraulic energy.
The pumps are intended for operation in open and close loops of stationary and mobile installations.

Working displacement: 28, 55, 56, 80, 107, 112, 160, 250 ccm/rev
