 Series 90 Pumps proven reliability, performance, compact and lightweight


S90



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 - advanced technology
• Seven sizes of variable displacement pumps
• Proven reliability and performance
• Compact, lightweight
• Worldwide sales and services
• Plus +1 compliant controls and sensors

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 or tiltable 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.
