Variable displacement axial-piston pumps in swashplate design are used for hydraulic actuators combined of pump and motor, operating in closed circuit systems. They are used for driving mobile machines like combines or rotating technological equipment like transit mixer drums etc. Axial-piston pumps are easily controlled and relatively compact. Pump flow is directly proportional to the cylinder block speed and displacement varied with the swashplate positioning. Flow direction is reversed with a tilt of the swashplate in either of the opposite directions from its neutral position.

Fixed displacement axial-piston motors in swashplate design are used both in closed and open circuits. Motor rotating speed is proportional to the flow which is supplied to it. Torque produced is proportional to the hydraulic pressure the motor receives. Shaft direction depends on to which port (A or B) pressure is supplied. Series MFH motors are relatively compact. There is an option of module adjustment of manifold block. H series motors are manufactured in two variants of bodies and end caps. Except module adjustment of manifold valve, there is an option with built-in valves to the end cap. It allows to reduce motor size.

Series ‘К’ gear pumps are manufactured with thru-bolt body of rolled aluminium, usage of solid sleeves of high-strength aluminium alloy and PTFE bearings. Gear pumps series ‘К’ are manufactured under the standard DIN, SAE.

Displacement - 34...100 cm3.Rated pressure - 18-28 MPa (180-280 bar).Max. rotational speed - 1800-2800 rpm.SeriesT gear pumps are manufactured with installation dimensions according to ISO standard. May be of right, left and bidirectional rotation.The main characteristic of these pumps is low sensitivity to axial and radial loads which permits to drive the pump using a pulley or a drive gear (spur or helical) installed on the pump shaft.Housing and covers for seriesT pumps are made of cast iron.The pumps are applied on dump trucks, truck mounted boom lifts.

Proportional pneumatic tipping valve with open center MR100.T1 suitable for medium- and heavy-duty trucks.

Directional control valves MP80 are used in hydraulic systems with flow up to 100 l/min. Designed for distribution and flow control between pump and actuators (hydraulic cylinders and motors). They are used in hydraulic systems of agricultural tractors BELARUS, XTZ, UMZ etc., and pipelayers ChTZ-URALTRAK.

Piston double-acting hydraulic cylinders. Rated pressure: 160 ... 250 bar. Maximum pressure: 200 ... 280 bar. Used in agricultural, road construction, utility machines and other equipment.

The hydraulic motors MFS series are a cost competitive solution for a variety of application conditions. Time-proven design, based on the Sauer 20 series, is reliable and durable in the field.

Variable displacement axial-piston hydraulic motor with a wide adjustment range, provides a high shaft speed and a high torque. The design is based on Sauer 20 series. It is used as a part of hydrostatic transmissions of mining machines.
