DOWELING PUMP CASING
The pump casing must be doweled to the base plate
pedestals to positively maintain position. Two (2) separate
methods are used by Truflo, depending on whether the
pump is used in a cold application or a hot application (see
below).
MOTOR INSTALLATION
1. Center the pump on its pedestal such that the hold down
bolts is centered in the tapped holes of the pump pedestal.
2. Place the motor on the base plate with the proper shaft
separation (DBASE = Distance Between Shaft Ends).
3. Tighten down on the pump hold down bolts.
4. After correct motor location has been determined on the
motor pedestals, transfer the location of the motor onto the
pedestals by hole punching the motor pedestal through the hold
down bolt holes in the motor feet.
5. Remove the motor, then drill and tap the punched holes on
the motor pedestal.
6. Set the motor back onto the baseplate with the shims in the
correct location. Tighten hold down bolts.
7. Loosen the pump and motor hold down bolts. Confirm that
the pump and motor are not bolt-bound. This step assures that
the final drilled holes will be correctly located.
NOTE: Pump is not doweled prior to this time because
the pump cannot be moved on its pedestals after it has
been doweled.
COLD SERVICE APPLICATION
NOTE: This procedure must be done only after the
pump is properly aligned with the driver on the
baseplate.
1. Drill two (2) holes, using a 21/64 in. or "Q" size drill
through the pump foot and pump pedestal. Position the hole
between the hold down bolt and the end of the pump foot at
the coupling end on both sides.
If water cooled pedestals have been provided do NOT
drill through the baseplate pedestal or leakage of
cooling water will occur.
2. Ream the holes with a Number 7 taper pin reamer to the
proper fit with the taper dowel pins. Pins should insert to a
depth that leaves only the threaded portion exposed when
fully seated.
3. Seat taper pins firmly in holes with hardwood block or
soft faced hammer.
Should it become necessary to remove the dowel pins,
tighten the hex nuts provided on the pins. If the pins are
not seated deeply enough, a spacer under the hex nut may
be required to lift the pins free when the hex nut is
tightened.
HOT SERVICE APPLICATION
Refer to Fig. 16 for Steps 1 through 5.

Remove the hold-down bolts from the pump feet
furthest from the coupling.

Scribe a mark mid-way between the end of the
pump foot and the hold down bolt whole centerline,
parallel with the pump axis.

Re-torque the hold down bolt between the pump
foot and the pump pedestal.

The pump foot and the outside of the pedestal will
not be flush. Mill or grind a spot on the pump pedestal to
make it flush with the pump foot.

Drill and ream for a 1.00 inch dowel pin, keeping
the pin flush with the pump foot.
When the driver is mounted at the factory, the pump is
doweled for both cold and hot applications. The driver is
not doweled to allow for final field alignment. When the
driver is mounted in the field, the pump is not doweled.
Therefore, the following procedure, typically done at the
Truflo manufacturing factory, must be done in the field.
NOTE: Scribe the motor shims in order to return them
to the correct location on the motor pedestal.
