CZPT fluid
Just before beginning undertaking plHangCZPT, remember to refer to our knowledge sheets RE 95710 (mineral oil), RE 95711 (environmentally appropriate hydraulic fluids) and RE 95713 (HF hydraulic fluids) for comprehensive data regarding the choice of hydraulic fluid and software conditions.
The mounted motor AA2FM is unsuitable for operation with HFA. If HFB, HFC and HFD or environmentally acceptable hydraulic fluids are getting employed, the limits relating to technological data and seals described in RE 95711 and RE 95713 have to be noticed.
Particulars concerning the decision of hydraulic fluid
The right option of hydraulic fluid requires information of the operating temperature in relation to the ambient temperature: in an open circuit the tank temperature. The hydraulic fluid ought to be chosen so that the operating viscosity in the functioning temperature selection is inside the the best possible range (νopt.) – the shaded location of the variety diagram. We suggested that the increased viscosity class be chosen in each scenario. Illustration: At an ambient temperature of X°F (X°C) an running temperature of 140°F (60°C) is established. In the the best possible running viscosity assortment (νopt shaded region) this corresponds to the viscosity lessons VG 46 or VG sixty eight to be picked: VG sixty eight.
Remember to observe: The case drain temperature, which is impacted by stress and velocity, is constantly larger than the tank temperature. At no level in the method might the temperature be larger than 240°C (115°C) for measurements 5 to 200 or 195°F (90°C) for sizes 250 to 1000.
If the earlier mentioned situations are not able to be preserved thanks to excessive working parameters, we suggest flushing the scenario at port U (dimensions 250 to 1000).
Long-life bearing (sizes 250 to one thousand) 
For extended provider daily life and use with HF hydraulic fluids. Identical exterior proportions as motor with standard bearing. A prolonged-lifestyle bearing can be specified. Flushing of bearing and case by means of port U advisable.
Shaft seal ring
The provider daily life of the shaft seal ring is afflicted by the speed of the motor and the situation drain pressure. It is advised that the regular, steady case drain force at operating temperature forty five psi (three bar) absolute not be exceeded (max. permissible case drain force to ninety psi (6 bar) complete at reduced velocity). Brief-term (t < 0.1 s) pressure spikes of up to 145 psi (10 bar) absolute are permitted. The service life of the shaft seal ring decreases with an increase in the frequency of pressure spikes. The case pressure must be equal to or greater than the external pressure on the shaft seal ring.
