SETTING THE PUMP:
Set pump on the foundation over the anchor bolts, but do not bolt down. Raise the pump unit 1" and level
carefully for grouting by driving wedges under the pedestal. For leveling pump, place level on face of pump
coupling half and face of pump discharge flange.
GROUTING THE PUMP:
After pump is raised and leveled, pour a good quality grout under the pedestal and allow it to set; to prevent
distortion, do not tighten down the nuts on the foundation bolts until the grout has properly hardened. When
the pump is correctly installed, bring the suction and discharge piping to the pump connections; never force
pump connections to install piping.
It is important that grouting underneath the base of a horizontal pump be carried out by pouring concrete
into the large opening in the center of all pump bases, otherwise the procedure is similar to the description
given above for the vertical units.
PIPING:
To obtain a well-designed pipe system, note the following piping recommendations:
1. Make pipe connections to the pump so that there is no pipe strain upon the unit. Support the weight of
piping on suitable concrete piers or on supporting pipes with flanged feet.
2. When running a pipe through a concrete wall, leave a generous, grooved, square hole and grout the pipe in
only after the pump unit is set and all final connections have been made.
3. Suction and discharge pipelines should not be smaller than the connections on the pump; it is preferred that
they should be at least a pipe size or two larger.
4. In the suction pipeline include a gate valve near the pump, and employ flexible pipe connections (see Fig. 3)
for ease in making final connections and to prevent pipe strain due to settling of concrete.
NOTE:
The gate valve's weight might produce a strain on the suction piping and therefore, the suction
piping should be supported on concrete piers, support pipes or hangers.
5. On the discharge line, include a suitable swing check valve and a gate valve near the pump.
NOTE:
It is common practice, where horizontal space does
not permit,
to mount swing check valve in a
vertical position.
6. On vertical units install a drain pipe from the connection at packing box drip pocket to the sump line. To be
readily cleanable, include a union in the line near the pump; also, tees with plugs should be used rather
than elbows.
TO INSTALL UNIVERSAL JOINT SHAFTING:
When installing extended shafting with universal joints, always place the section with the slip spline end (at
the bottom), with spline next to the pump. When more than one section is provided, the order of connection
is evident from the connection fittings provided and from the installation drawing; the opposite shafting ends
are fis ed to the pump and motor shafts by means of keyed couplings held with set screws. Connect the
shaft sections and align them approximately, fixing the shafting temporarily but firmly to the bearing support
beams by clamping the intermediate guide or steady bearings to the beams with a sufficient number of "C"
clamps. Caution! One side of the intermediate bearing housing has a drilled drainage hole. Be sure when
installing that this bearing is installed properly to provide drainage of topside of bearing. When all sections
are joined, align each section separately with a level as accurately as possible, starting from the bottom and
using metal shims behind the steady bearings where necessary. Although universal joints will compensate
for considerable misalignment, for maximum efficiency, shafting manufacture recommends an offset of 1/8”
– 3/16” per foot of shaft length.
In making final adjustments, the slip spline should be spaced, as near as possible to the mid-point of its slip
or end play, there must be enough slip to separate the flexible shafting from the pump coupling. Steady
bearings are of the self-aligning type, perfect leveling of the bearings is not necessary; and since steady
bearings are not provided to stand end-thrust, the shafting weight should be taken by the motor bearings.
When alignment is completed, drill holes in the bearing supports and bolt bearings in place. Remove "C"
clamps.
