SITE/FOUNDATION

The pump should be located where there is
adequate space for installation, operation,
maintenance, and inspection. Make sure there is
adequate overhead clearance for installing and
removing the pump. There should be at least 1/2”
clearance between the sides of the pump and
any portion of the pit.

Vertical sump pumps are normally bolted to a
concrete sump or steel tank. The supporting
structure must provide a permanent rigid support

for the pumping unit(s) to eliminate any possible
vibration. Support plates and/or pit covers are not
normally grouted in place. The location and size
of the mounting bolt holes are shown on the
pump outline drawing provided with the pump
data package. If anchor bolts are to be poured
into the concrete, it is recommended that a
sleeve type as shown in Figure 5 be used to
allow for adjustment.

WHEN PIT COVER IS USED

If access to the bottom of the pit cover is not
possible during the installation process, the
pump (less motor), support plate and pit cover
must be assembled and installed as a unit.

1. The pit cover must be installed level to insure

that the pump remains plumb when installed.


2. Carefully lower pit cover foundation bolts.

3. Using as long a level as practical, level the

pit cover in all directions with shims or
wedges.


4. Hand tighten the anchor bolts, check the

level and re-shim if necessary.


5. Tighten all anchor bolts in a star pattern to

avoid distorting the support plate.


6. If access to the bottom side is possible,

carefully lower the pump and support plate
onto the pit cover.


7. Install all bolts finger tight.

8. Check level on support plate and shim if

necessary.

9. Tighten all bolts in a star pattern to avoid

distorting the support plate.

Vapor Proof Option


The vapor proof option includes machined,
gasketed fits between the support plate/pit cover
and the pit cover/foundation. These gaskets
must

be

installed

to

insure

emissions

performance. The pit cover should be bolted to a
metal sole plate with a machined surface to
insure an airtight seal.
