Product Description

Sauer 90M042 90M75 90M55 90M100 Hydraulic Motor For Road Roller

Series 90 hydrostatic pumps and motors can be applied together or combined with other products in a

system to transfer and control hydraulic power. They are intended for closed circuit applications.

Series 90 variable displacement pumps are compact, high power density units. All models utilize the

parallel axial piston/slipper concept in conjunction with a tiltable swashplate to vary the pump's

displacement. Reversing the angle of the swashplate reverses the flow of oil from the pump and thus

reverses the direction of rotation of the motor output.

Series 90 pumps include an integral charge pump to provide system replenishing and cooling oil flow, as

well as control fluid flow. They also feature a range of auxiliary mounting pads to accept auxiliary

hydraulic pumps for use in complementary hydraulic systems. A complete family of control options is

available to suit a variety of control systems (mechanical, hydraulic, electric).

Series 90 motors also use the parallel axial piston/slipper design in conjunction with a fixed swashplate.

They can intake/discharge fluid through either port; they are bidirectional. They also include an optional

loop flushing feature that provides additional cooling and cleaning of fluid in the working loop.

• Series 90 - advanced technology today
