Hawe R9,8A Pump

Cleanliness level
ISO 4406 21/18/15...19/17/13 see oil recommendation D 5488/1
Temperatures
Environment: approx. -40 to +80 °C, hydraulic uid: -25 to +80 °C, pay attention to the viscosity range.
Start temperature: down to -40 °C is permissible (take account of the start viscosities!), as long as the
steady-state temperature is at least 20 K higher during subsequent operation.
Biologically degradable hydraulic uids: note manufacturer specifications. With consideration for the seal
compatibility, not above +70°C.

Flow rate
Pressure side (outlet):
depending on piston diameter, see Chapter 2, "Available versions"
Suction side:
