5 Pump Installation
5.1 Pump Installation
NOTICE:
Pump Installation: All bolts are torqued by the factory and secured with Loctite. It is recognized
that transportation and handling may result in bolt relaxation, therefore, check that all fasteners
on the pump are tight prior to installation.
• Preliminary precautions should be taken prior to the final installation of the pump. The well and well
site should be examined carefully in the following manner.
1. Check to insure sand has not covered the perforated sections of the well.
2. Determine that the well is of ample diameter and depth and is sufficiently straight to receive the
pump. The submersible unit must be operated in a straight portion of the well. Exerted pres-
sures can and will cause misalignment of bearings or
couplings. When the straightness of the well is not known, it is recommended to lower a test blank
with the same diameter and length as the combined pump/motor assembly with electrical leads into
the well to the desired depth. If there is any doubt about straightness, caging and plotting are rec-
ommended.
CAUTION:
Never install unit with the bottom of the motor closer than five feet from the bottom of the well.
NOTICE:
In a previously used well, any obstruction such as jagged casing or other damage should be
removed or corrected. Visual inspection may be performed through the use of an underwater
television camera.
3. Any oil or oil emulsion must be removed from the surface of the water to prevent premature
damage to the unit. It is possible to prevent fluid from entering the unit during installation by
wrapping with an envelope of water soluble polyvinyl alcohol, but this will not protect the jacket
material of the electrical conductor.
4. Survey the well
Many wells have more than one size of casing installed and frequently the lower sections are small-
er in diameter than the upper casing.
CAUTION:
Do not install the unit with the motor in mud, sand, or resting on the bottom of the well. It is
important to prevent the well from sanding up at any time to the point that the motor becomes
even partially buried.
5.2 Preparing the Foundation
The foundation must be rigid, level, and of adequate strength to support the complete weight of the
pump, motor, column, plus the weight of the liquid passing through it. It is recommended the foundation
