FRR090C FRL074B FRL090C FRL Sauer FRR Pump. FRR074 FRR090 FRL074 FRL090 future below:
variable displacement, axial piston pumps for open circuit applications. Each frame within the Series 45 family is uniquely
designed to optimize performance, size, and cost, matching the work function requirements of the demanding mobile equipment
marketplace.
Details regarding the choice of hydraulic fluid:
The correct choice of hydraulic fluid requires knowledge of the operating temperature in relation to the ambient temperature: in a
closed circuit the circuit temperature.
The hydraulic fluid should be chosen so that the operating viscosity in the operating temperature range is within the optimum
range (νopt)
- the shaded area of the selection diagram. We recommended that the higher viscosity class be selected in each case.
Example: At an ambient temperature of X °C an operating temperature of 60 °C is set. In the optimum operating viscosity range
(νopt; shaded area) this corresponds to the viscosity classes VG 46 or VG 68; to be selected: VG 68. Please note: The case drain
temperature, which is affected by pressure and speed, is always higher than the circuit temperature.
At no point in the system may the temperature be higher than 115 °C. If the above conditions cannot be maintained due to extreme
operating parameters, please consult us.
Hydraulic fluid; Before starting project planning, please refer to our data sheets RE 90220 (mineral oil), RE 90221
(environmentally acceptable hydraulic fluids) and RE 90223 (HF hydraulic fluids) for detailed information regarding the choice of
hydraulic fluid and application conditions. The variable pump A4VG is unsuitable for operation with HFA, HFB and HFC. If HFD or
environmentally acceptable hydraulic fluids are being used, the limitations regarding technical data and seals mentioned in RE
90221 and RE 90223 must be observed. When ordering, please indicate the used hydraulic fluid.
