See installation examples, chap. 14 fig. 1 and 2.
The pumps must be installed with the rotor axis in the
horizontal position and with the feet under the pump.
Place the pump as close as possible to the suction
source.
Provide space around the pump for motor ventilation,
for checking the direction of rotation of the shaft,
for filling and draining the pump and to allow for the
collection of the liquid to be removed.
6.4.1. Pipes
Make sure that the insides of the pipes are clean and
unobstructed before connection.
ATTENTION: the pipes should be secured to their
supports and connected in such a way that they
do not transmit stress, strain or vibrations to the
pump (par. 14 fig. 3).
Tighten the pipes or union coupling to the extent
sufficient to ensure a tight seal.
Excessive tightening may cause damage to the pump.
The pipe diameters must not be smaller than the pump
connections.
6.4.2. Suction pipe
The suction pipe must be perfectly airtight and be led
upwards in order to avoid air pockets.
With the pump located above the water level (suction
lift operation, chap. 14. fig. 2) fit a foot valve with
strainer which must always remain immersed.
If operating with flexible hoses use a reinforced
spiral suction hose, in order to prevent the hose from
narrowing due to suction vacuum.
With the liquid level on the suction side above the
pump (inflow
under positive suction head, chap. 14.
fig. 1) fit an inlet gate valve.
