Duraforce HMR Regulated Variable Displacement Piston Motors

HMR Series piston motors deliver high efficiency, precision control and durability over the course of many years of reliable service. They are high-pressure regulated and shift to minimum displacement Vmin at system pressures below the regulation begin point. When the defined high pressure regulation set point is reached, the motor smoothly increases displacement to match the torque required by the system.

Features
