7.3.1 Start up
Start up Pre-Conditions:
• Pump has been filled. Ö Chap. "7.1.1 Filling up the Pump", Page 44
• The temperature of the operating fluid in the tank does not exceed the
pump temperature by more than 25 °C.
Procedure:
1. Start up the drive motor.
2. Check the rotational direction of the drive motor.
3. Operate the pump at low pressure until the hydraulic system has been
de-aerated.
4. For pumps with HF fluids: Run the pump for approx. one hour at low
pressure (30–50 bar).
7.3.2 Flushing the Pump
Flushing the Pump
Procedure:
1. The flushing line must be connected to the pump's lowest leakage
connection.
2. Flush the pump using operating fluid quantities depending on pump size:
If the temperature of the operating fluid in the tank exceeds the pump
temperature by more than 25 °C, the pump should only be switched on in
short intervals of 1 to 2 seconds until it has heated up.
It is forbidden to blow off the shaft seal directly with compressed-air.
It is also forbidden to spray and flush the shaft seal directly with
pressurized fluids.
If the pump is operated for longer periods of time at low pressure without
delivery (t > 15 min, p < 30 bar, Q = 0 l/min) it will be necessary to flush
the pump to dissipate the heat.
