9.10 V-belt Transmission
As indicated in paragraph 9.1, only in exceptional cases may the pump be driven by a v-belt system. For correct lay-out
sizing, please contact our Customer Service Department.
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 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 position 2, fig. 9). Be sure to reclose the valves before the
pump start-up. See fig. 10 for “work” and “rest” positions.
