OPT.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/re
