Danfoss recommends testing to verify that these temperature limits are not exceeded. Viscosity For maximum efficiency and bearing life, ensure the fluid viscosity remains in the recommended range.

  • Page 13: System Design Parameters

    Technical Information Series 90 Axial Piston Pumps System Design Parameters Filtration System To prevent premature wear, ensure only clean fluid enters the hydrostatic transmission circuit. A filter capable of controlling the fluid cleanliness to ISO 4406 class 22/18/13 (SAE J1165) or better, under normal operating conditions, is recommended.

  • Page 14: Charge Pressure Filtration (Partial Charge Pump Flow)

    Charge pressure filtration (partial charge pump flow) Two types of pressure filtration exist for most Series 90 pumps. The two types are: remote pressure filtration (filter remotely mounted on vehicle) and integral pressure filtration (filter mounted to the endcap).
