Hydraulic gear motor
10 - 100 cc/r | QM series Jihostroj

The QM series hydraulic gear motors have a design which arises from the Q series gear pumps. Their body is made of aluminium alloy, flange and cover are of cast iron, the gears are of steel. They are equipped with the hydraulic balancing of axial clearance. Their modern design enables remarkable better parameters of noise, higher working pressure with higher capacity, torque and efficiency within the whole range of speed and temperature. They are being manufactured in unidirectional design as clockwise or anticlockwise motors, they can be in a reversible version, too.

For difficult operations with axial load and hard radial load of driving gear is in this series available hydraulic motor with auxiliary bearing in the flange.

The range of geometrical volumes of the motors are Vg=10 to 100 ccm/rev, the range of working speed is from 500 to 3000 min-1 and maximal working pressure is 290 bar.

The hydraulic motors are being manufactured in a wide range of drives, connecting flanges and fluid inputs and outputs. They conform to the ISO, SAE and other worldwide accepted standards.
