OPT.614 Series

Closed circuit variable displacement axial piston swashplate hydraulic pump.

Purpose:
The pumps transform the shaft rotation mechanical energy into the working fluid energy.
Hydraulic pump feed is proportional to the shaft rotation frequency and working displacement. Working displacement value is step-less regulated from zero up to the max value to each side. Fluid feed direction can be reversed by means of swash plate swivel change into the opposite side from the neutral position.
G1.614 series pumps are intended for operation in stationary and mobile installations inset with hydrostatic transmissions (HST).

Working displacement: 28, 71, 90, 110, 125 ccm/rev
