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 cor-
rect lay-out sizing, please contact our Customer Service
Department.
The diagram does not take into account the hose
and valve resistance, the pressure drop due to
the pipe length, the viscosity and the temperature
of the pumped fluid. If necessary, 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 pres-
sure (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 ex-pulsed
easily, thus facilitating pump priming.
3. All suction/delivery connections and fittings
must be correctly tightened.
4. Coupling tolerances on the pump/transmis
sion 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 the valve positions.
