6.4 INSTALLATION EXAMPLE
When positioning and installing the pump, follow the installation examples below in order to avoid damaging the pump.
1. Pipe support: Support piping
system properly to avoid stresses
on connections.
2. On-off valves: Install on-off
valves for easy access- before the
pump intake and after the pump
discharge.
3. Use exible piping on both inlet
and outlet sides of the pump to
reduce vibration and transmission
of noise.
4. Check valves will prevent return
ow of pumped liquid when pump
is stopped, reducing the danger of
pump damage.
5. Control Panel: Use high quality
components. Make sure that the
panel conforms to local standards
and regulations.
6. Do not place elbows next to the
pump inlet and discharge.
7. If pump needs to be operated
with on-off valve closed, install a
by-pass line to avoid damaging the
pumping system.
8. If it is necessary to increase the
diameter of the suction pipe,
place an eccentric reducer
between the check valve and the
exible pipe section.
9. Using elbows will increase the ow
resistance. Long radius bends will
result in less ow resistance.
10. The piping must have a level or
positive gradient to prevent the
formation of air pockets.
11. The diameter of the drop pipe
must be bigger than the diameter
of the pump’s suction port.
12. Use a foot valve in case of
negative suction head.
13. Size pump for correct head.
14. Place the intake of the suction
pipe so that the footvalve is always
submerged to prevent entry of air.
15. Install a compound gauge at the
pump suction and a pressure
gauge at the pump discharge.
CHAPTER 7
ELECTRICAL CONNECTION
• All electrical connection should be in
accordance with the local regulations
and made by a qualied electrician

and discharge sides of the pump, thus
making the lling procedure easier.
When the operation is stable, the
bypass valve can be closed.
• If the pumped liquids contains air, it
is advisable to leave the bypass valve
open if the operating pressure is
lower than 6 kg/cm². If the operating
pressure constantly exceeds 6 kg/
cm² the bypass valve must be closed.
Otherwise the material at the opening
will be worn because of the high liquid
velocity.
