3.2 System sizing
The pump is factory-set to 3 bar (44 psi) outlet
pressure which can be adjusted according to the
system in which it is incorporated.
The tank precharge pressure is 1.25 bar (18 psi).
In case of suction lift of more than six metres, the
pipe resistance on the outlet side must be at least
two metres water column or 3 psi at any given flow in
order to obtain optimum operation.
3.3 Mechanical installation
3.3.1 Positioning the product
Always mount the pump on the base plate in a
horizontal position with a maximum inclination angle
of ± 5 °.
3.3.2 Foundation
Fasten the pump to a solid horizontal foundation by
means of screws through the holes in the base plate.
See figs 1 and 2.

3.3.3 Connecting the piping system
1. Turn the union nuts by hand to loosen the inlet
and outlet ports. See fig. 3.
2. Seal the pipe fittings with thread sealing tape.
3. Carefully screw the inlet and outlet connections
to the pipe fittings using a pipe wrench or similar
tool. Keep the union nut on the pipe fitting if you
have removed it from the pump.
The pump is equipped with flexible connections,
± 5 °, to facilitate the connection of inlet and
outlet pipes.
4. Fasten the connections to the inlet and outlet.
Hold the connection with one hand and tighten
the union nut with the other hand.

How to fit the connections
Make sure that the system in which the
pump is incorporated is designed for the
maximum pump pressure.

Make sure that the pump is not stressed
by the piping system.
Always loosen and tighten the union nuts
on the inlet and outlet ports by hand.
Damage to the inlet and outlet parts
increases the risk of leakage.
