Gear Motors

Series PM23, TM3, QM2, JM and UMD

The PM23 series hydraulic gear motors are used for transformation of liquid pressure head in mechanical energy. PM23 series motors are designed for advanced hydraulic systems with lower capacity (approximately up to 8 kW) with high operational reliability and long service life. They have been produced in both one-way and reversible version with internal or external drainage. A wide variety of designs with diverse drives, connecting flanges, fluid inlets and outlets enable the motors to be used in hydraulic systems of both fixed and mobile machines and equipment. Types of connections and flanges as well as the other connecting dimensions correspond to all worldwide standards.
The motors are made of high-quality aluminium alloys with steel gear-wheels and they are equipped with hydraulic axial play compensation of new generation ensuring stable performance and torsion moment within the entire range of speeds and temperatures. As for their dimensions, PM23 motors are fully interchangeable with PM and PM2 motors..

The TM3 series hydraulic gear motors are used for transformation of liquid pressure head in mechanical energy. TM3 series motors with external teeth are due to their simple construction, compact dimensions and a wide range of types applicable in modern hydraulic systems, handling equipment as well as mobile hydraulic systems. Flange types used as well as the form of working liquid inlet and outlet comply with all worldwide standards. The PM23 series covers the range of displacements from 9 to 31 cm3/rev.
The basic version consists of several parts. The body is made of a heavy duty aluminium alloy, engine cover and flange of grey iron or eventually aluminium alloy, and gear wheels of heavy duty steel. Axle pins with a high surface duality are imbedded in sliding sleeves, continuously lubricated and cooled by a stream of working liquid. The axial pump balancing is performed using sliding aluminium alloy bearing sleeves in which a shape sealing of balancing surface is located in grooves. TM3 series motors can be delivered in one-way design as clockwise or anti-clockwise rotating engines; they are also available in reversible version.

 

The QM2 series hydraulic gear motors are used for transformation of liquid pressure head in mechanical energy. QM2 series motors with external teeth are due to their simple construction, compact dimensions and a wide range of types applicable in modern hydraulic systems, handling equipment as well as mobile hydraulic systems. Flange types used as well as the form of working liquid inlet and outlet comply with all worldwide standards. The QM2 series covers the range of displacements from 10 to 100 cm3/rev.
The basic version consists of several parts. The body is made of a heavy duty aluminium alloy, engine cover and flange of grey iron or eventually aluminium alloy, and gear wheels of heavy duty steel. Axle pins with a high surface duality are imbedded in sliding sleeves, continuously lubricated and cooled by a stream of working liquid. QM2 series motors can be delivered in one-way design as clockwise or anti-clockwise rotating engines; they are also available in reversible version.

 

The JM series gear motors are used for transformation of liquid pressure head in mechanical energy. The JM line motors are designed for advanced hydraulic systems with lower capacity (approximately up to 10 kW) with high operational reliability and long service life. A wide variety of designs with diverse drives, connecting flanges, fluid inlets and outlets enable the motors to be used in hydraulic systems of both fixed and mobile machines and equipment. The JM series covers the range of displacements from 2 to 15 cm3/rev.
The flange types used as well as the form of the working liquid inlets and outlets (located laterally - in the body or axially - in the cover) meet all worldwide standards. The pump body is made of a heavy duty aluminium alloy. The cover and the flange are made of grey iron or aluminium alloy, and gear wheels of heavy duty steel. Axle pins with a high surface duality are imbedded in sliding sleeves, continuously lubricated and cooled by a stream of working liquid. JM line motors can be delivered in one-way design as clockwise or anti-clockwise rotating engines; they are also available in reversible version.

Gear motors of UMD series are used for transformation of liquid pressure head in mechanical energy. Cover and flange are manufactured of grey iron. The body is designed from of shaped profile bars from aluminium alloy. They meet all world standards, as well as execution input and output of the working fluid (the location on the side - in the body or axially - in the cover). Motors are connected with four through-bolts from M12 high strength steel. They are equipped with a hydraulic pressure compensation axial-clearance which is executed by means of a balancing sealing directly in the bearing sleeves. UMD motors are manufactured in a unidirectional design as clockwise or anticlockwise motor can be reversible in the embodiment.
