PREPARING THE PARTS FOR INSTALLATION
All of the pump parts were carefully
inspected before leaving the factory, but
may have become soiled or damaged in
shipping and handling. Therefore, all
parts must be inspected by the installer
to verify that they are clean and
undamaged before installing them.
Check all column, tube, and shaft
sections to ensure that they have not
been bent, and that machined surfaces
are not marred in any way, especially the
mating surfaces and threads. A
procedure for testing shaft straightness is
specified on the following page.
If the shaft sections were shipped
crated, they should be removed from the
crate at this time. The top shaft section
can be identified by the keyseat and
extra long threaded section at the upper
end. Some pumps have a short shaft
section just below the top shaft section,
which is called the head shaft (or
“second top shaft”). The shaft ends may
be threaded to engage in a threaded
coupling, or they may have a keyway
(keyseat) and ring groove (annular
keyway) for a split-ring coupling.
Lay the shaft sections across the
parallel timbers previously placed on the
ground.
Do not step or walk on the shafts.
Do not place other parts or equipment
on the shafts. Use appropriate solvent
to wash off any protective coating from
the shaft sections, and wipe thoroughly
clean and dry. Clean the shaft coupling
threads using a wire brush and solvent,
cover both ends, and store couplings in a
clean place until ready for use.
Unless the pump is a short setting
unit and was shipped from the factory
pre-assembled, ALL installation and
assembly must be done vertically. If the
unit was shipped assembled from the
factory, check all pump, tube (if
applicable) and column joints for
tightness with the pump in the vertical
position and with its weight borne by
support clamps around the well or sump
opening.
Do not attempt to assemble the
bowl, column, enclosing tube, shaft, and
discharge head horizontally on the
ground before installation. Horizontal
assembly risks damage to the shaft
sections, tubing, and possibly the
column pipe. Bending of any of these
components will cause malfunction of
the pump.
The well or sump must be
thoroughly cleaned of dirt, debris and
contaminants before installing the pump.
After the installation, the well or sump
should again be inspected for foreign
matter, and cleaned if necessary. If it is
suspected that the fluid will contain
sizable solid particles or that foreign
objects may enter the sump or well, a
suction strainer should be installed with
the pump and cleaned periodically.
Your Peerless Pump dealer will be glad
to advise you on the need for a suction
strainer. Dirt, sand, etc. in the sump or
well will cause premature wear on the
critical pump internal surfaces, resulting
in reduced pump performance.
