10. START-UP AND OPERATION
10.1 Preliminary Inspections
Before Start-up Be sure that:
The inlet line is connected and up to pressure (see Chapter 9) the pump must NEVER run dry.
1. The inlet line must be perfectly airtight.
2. All the On-Off valves between the pump and the feeding source are completely open. The outlet line must
discharge freely in order to allow the air in the pump to be expulsed easily, thus facilitating pump priming.
3. All fittings and connections must be correctly tightened.
4. Coupling tolerances on the pump/transmission axis (half-joint misalignment, Cardan inclination, belt
tightening, etc.) must remain within the limits indicated by the transmission Manufacturer.
5. The pump’s oil level must be verified using the correct dipsticks (position 1, fig 8).
In case the pump has not run for a long period of time, recover the correct operation of the suction valves
by opening the three valve-lifting devices (see fig. 9). Be sure to reclose the valves before the pump
start-up.
10.2 Start-up
1. When starting the pump for the first time, check for the correct direction of rotation.
2. The pump must be started off-load.
3. Verify correct feeding pressure.
4. During operation, check that the rotating speed does not exceed the rated value.
5. Before putting the pump under pressure let it run for at least 3 minutes.
6. Before stopping the pump, release the pressure by acting on the adjustment valve or on any discharging device.
