10. START-UP AND OPERATION
10.1 Preliminary Inspections
Before Start-up Be sure that:
The suction line is connected and up to pressure (see Chapter 9) the pump must never run dry.
1. The suction line must be perfectly airtight.
2. All the On-Off valves between the pump and the feeding source are completely open. The delivery line must
discharge freely in order to allow the air in the pump to be expulsed easily, thus facilitating pump priming.
3. All suction/delivery connections and fittings 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 14), and especially by means
of the oil sight glass (position 2, fig. 14).

KF SERIES
In case the pump has not run for a long period of time, verify the correct operation of the suction and
delivery valves.
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.
