Pump-axial-piston-piston adjustable types MGP112/32m with proportional hydraulic regulation are used in volumetric hydraulic drives of machines and assemblies in the regimes of the adjustable pump or hydraulic motor.
The pump is designed to convert the mechanical energy of rotation of the drive shaft into the variable energy in terms of working fluid flow (in a closed scheme).
The hydraulic engine is designed to drive actuators requiring unaccountable control of the rotation frequency.
The beginning of the regulation of the working volume is from the maximum (negative management).
