SECTION V. INSTALLATION
1. Deep well
a. The well must be complied with necessary codes.
b. Quality of water inside the well must be checked, free from any excess mud or sand to avoid
overheat of motor and damaging the internal parts of the pump.
c. Water capacity inside the well should be equal or more than the capacity of pump to avoid dry
run operation (operating without water).
d. Drawdown level must be at least 10ft higher than the pump suction of the pump.
e. Submersible motor must be cooled at all times. If motor temperature is increasing due to
several reasons, flow inducer tube or shroud may be required. Please check IOM manual of
submersible motor for details.
f. Inside well diameter casing must be large enough to install the submersible pump without
scratching or denting the pump & motor surface including the submersible drop cables.
g. It is required to install necessary device or components for protection against dry run
operation (operating without water).
2. Above Ground (Elevated) or Below Ground (Cistern) Water Tank
a. Above or below ground water tanks must be complied with necessary codes.
b. Water tanks must be free from any constructions debris, large solid particles or welding fluxes
to avoid damaging the internal parts of the pump.
c. Submersible pump may be installed in vertical position provided that the water level should
not reach the valve casing outlet of the pump to avoid producing water vortex during
operation.
d. Submersible pump may be installed in horizontal position provided that the water level should
not reach 5ft from the pump suction. Baffle plate or anti-vortex plate must be installed within
pump suction area if distance of 5ft cannot be attained.
e. It is required to install necessary device or components for protection against dry run
operation (operating without water).
3. Piping Connections
a. Procedure of installation of piping connections shall be in accordance to related plumbing
and/or water system codes & local regulations.
b. For deep well, check valve may be installed in vertical column pipe or main riser column pipe
for every 100ft to avoid surge back flow and water hammer when operation stops.
c. Proper support brackets and/or thrust blocks in discharge pipe must be installed.
d. Valves, fixtures and fittings must be followed in accordance to plumbing and/or water system
codes & local regulation with all necessary mechanical valves to protect the pump and piping
system during operation.
