Theor. displacement	See Specifications
Drive	Drive direct with flexible coupling is recommended.
Axial / Radial load	Units subject to axial or radial loads must be specified with an outboard bearing.
Inlet pressure	Operating range 0.8 to 2 bar abs. Min. inlet pressure 0.5 bar abs. Short time without load. Consultation is recommended.
Outlet pressure	See Specifications
Hydraulic fluids	Hydraulic oil HLP,DIN 51524-2
Fluid viscocity	See Nomograph for Pipe Velocity
Fluid temperature	Range of operating temperature -15 to +80 °C. Max. permissible operating pressure dependent on fluid temperature. Temperature for cold start -20 to -15 °C at speed ≤ 1500 rpm. Max. permissible operating pressure dependent on fluid temperature.
Fluid viscosity	Range of operating viscosity 8 to 1000 mm2/s. Max. permissible operating pressure dependent on viscosity. Viscosity range for cold start 1000 to 2000 mm2/s at operating pressure p≤10 bar and speed n ≤1500 rpm.
