Fluidtemperature
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.
Range of ambient temperature
-40 °C to +70 °C
Filtration
According to ISO 4406 Cl. 19/17/13
Directionofrotation (lookingatthedriveshaft)
CW, CCW, Bi-Rotational
Multiplepump assemblies
Available in two or three section configuration. Max. shaft load must be conform to the limitations shown in the shaft loading rating table in this catalogue. Max. load is determined by adding the torque values for each pumping section that will be simultaneously loaded.
Separateorcommoninlet capability
Separate inlet configuration: Each gear housing has individual inlet and outlet ports. Common inlet configuration: Two gear sets share a common inlet.
