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).
Finally, given a distance between pulley centers of 23.6 inches (600 mm) and a load of 75 N at the middle of the
distance, a belt flexion “te” of around .425 inch (10.8 mm) will confirm the correct belt tension as shown in fig. 13.
Note 1: If not differently indicated by the belt Manufacturer, the inspection of the correct tension value, and the related
tension adjustment if needed is to be carried out after at least 30 minutes of operation in order to obtain belt setting. The
best efficiency and maximum belt life is obtained with the correct tension value.
Note 2: If required, or during normal maintenance, never replace a single belt, but the entire set.
