Danfoss Series 90 Fixed Piston Motors

Danfoss Series 90 Fixed Piston Motors is designed in a fixed swashplate and a parallel axial piston/slipper configuration. These motors are used in many closed-circuit applications, with maximum displacements between 55 cm3 and 130 cm3 [3.35 in3 and 7.90 in3] and maximum operating pressures of 450 bar [6,525 psi]. They are bidirectional and may intake or discharge fluid through either port. These motors can be combined with Series 90 pumps or other Danfoss products to transfer and control hydraulic power.

With millions of units worldwide, Danfoss Series 90 motors have a stellar reputation. They provide high flexibility and high-power performance, which has the same appearance and feel over its whole range. They are bidirectional and can take in or release fluid through either port. Additionally, Danfoss Series 90 fixed piston motors have an optional loop flushing mechanism that offers more fluid cleansing and cooling in the working loop.

Danfoss Series 90 motors have several S90MF displacements available, ensuring the proper flow for the task. The S90MF modular design approach makes it simple to suit in a variety of applications. These motors are developed with special features, such as the integrated loop flushing valve, that ensure quick and simple integration. With working pressure ranges up to 420 bar, 55 cc and 75 cc are also available as cartridge motors.
