ALIGNMENT TROUBLESHOOTING
GROUT BASEPLATE
1. Clean areas of baseplate that will contact grout. Do
not use oil-based cleaners because grout will not bond
to it. Refer to grout manufacturers instructions.
2. Build dam around foundation. Thoroughly wet
foundation (Fig. 11).
3. Pour grout through grout hole in baseplate, up to level
of dam. Remove air bubbles from grout as it is poured
by puddling, using a vibrator, or pumping the grout
into place. Non-shrink grout is recommended.
4. Allow grout to set.
5. Fill remainder of baseplate with grout. Remove air as
before (Fig. 12).
6. Allow grout to set at least 48 hours.
7. Tighten foundation bolts.
ALIGNMENT CHECK
Re-check alignment before continuing, using methods
previously described.
PIPING
!
Flange loads from the piping system, including
those from thermal expansion of the piping, must
not exceed the limits of the pump. Casing
deformation can result in contact with rotating parts
and result in excess heat generation, sparks and
premature failure.
GENERAL
Guidelines for piping are given in the “Hydraulic Institute
Standards” available from: Hydraulic Institute, 30200
Detroit Road, Cleveland, OH 44145-1967 and must be
reviewed prior to pump installation.

Problem Probable Cause Remedy
Cannot obtain horizontal (Side-to-Side)
alignment, angular or parallel
Driver feet bolt bound.
Loosen pump hold-down bolts and slide
pump and driver until horizontal alignment is
achieved.
Baseplate not leveled properly, probably
twisted.
Determine which corner(s) of the baseplate
are high or low and remove or add shims at
the appropriate corner(s) and realign.
Cannot obtain vertical (Top-to-Bottom)
alignment, angular or parallel
Baseplate not leveled properly,
probably bowed.
Determine if center of baseplate should be
raised or lowered and correct by evenly add-
ing or removing shims at the center of the
baseplate.
