• A proper installation and sizing of the suction line are of particular importance for a correct operation of the pump, the following
factors shall be taken into account
:
A) Pipe inner diameter
The pipe internal diameter will be chosen according to the pump flow rate (see table C)
.
The pump connections are oversized, in order to cover all applications.
B) Length of the piping
Suction piping is to be as short as possible, following the indications of table C
it is suggested:
- Max suction lift 1,5 metres
- Total length 2,5 metres (upright plus horizontal)
C) Arrangement of the suction line
For the arrangement of the suction line see Fig. 7/A and 7/B.

• Provide with adequate clearance areas and safe access for operation and mainte-
nance, in particular in front of the hydraulic side and of the adjustment knob (fig. 6).
• If the pump is installed outdoors, a shelter is recommend, specially when the pump is
equipped with electric actuators or other delicate devices.
• PP pump heads can work properly only at ambient temperature and metered liquid
temperatures below 40°C.
• If necessary, provide suitable protection from sun rays and check the temperature of
the metered liquid.
