Description

Unregulated axial piston pump motor MN 250/160

Pump - axial piston motors with fixed bent axis type MN250 / 160 are used in volumetric hydrodrives machines and units in fixed displacement pump or motor mode.


The pump is designed for converting mechanical energy of rotation of the drive shaft in the hydraulic energy of working fluid.
Hydraulic converts hydraulic energy of the working fluid stream into mechanical energy of rotation of the output shaft.
Pump motor is made with both the valve box, and without it. The valve unit is mounted on the rear cover and the pump motor is designed to protect against overload of the hydraulic system, in which the pump motor is turned on. Recommended grade oils: VMGZ TU38.101479, MGE - 46B TU 38.001347, TNK Hydraulic HLP 32, 46, 68 TU38.301 - 41 - 180 - 01 LUKOIL Geiser ST 22, 32, 46 TU / TS 0253 - 011 - 79345251 - 2008.
