Installation Of Motor
1. Position the bracket on the motor with the mount-
ing feet pointing toward the motor. Motor vents should
be located on the bottom. To assemble use (4) allen
head cap screws (3/8”-16x1”) and (4) 3/8” external
serrated lock washers. Tighten securely with a 5/16”
allen wrench.
2. Position the cover over the motor shaft. Align the
(8) holes in the cover with those in the bracket. Then,
firmly press the cover into position.
Make certain the motor is not connected to a power
source. Do not assemble the pump on a motor con-
nected to a power source. Serious injury could occur
if the motor starts during pump assembly.
Position the motor on its end with the shaft up. The
work surface should be level and capable of support-
ing the motor.
Mechanical Seal Installation
1) Lubricate the rubber element of the ceramic
mechanical seal seat with mineral oil. Using a 3/4”
socket or piece of 3/4” PVC pipe, press ceramic seat
firmly and squarely into the seal cavity. Be sure the
seal face is not damaged during assembly (cracked,
scratched, or chipped) or the seal will leak.
2) Clean polished surface of ceramic seat with a soft
cloth or tissue to remove all dust and grit.
3) Inspect motor shaft to make sure it is clean.
4) To prevent slip-stick, lubricate both the ceramic
and carbon seal face with mineral oil. Do not let oil
get on to the motor shaft or the rubber driving ring of
the mechanical seal.

1. Reposition motor horizontally.
2. To screw the impeller onto the motor shaft, remove
the motor end cap located on the end oppsite the
motor shaft.
3. While preventing the rotation of the exposed motor
shaft, screw the 3/4” threaded impeller hub diameter
protruding from impeller onto the motor shaft, continue
until it contacts the shoulder on the motor shaft.
6. Position the Viton o-ring over the cover. Do not
nick or damage the o-ring during installation.
7. The casing can be positioned in the direction
desired.
a) Position the casing over the cover.
b) Rotate the discharge in the casing to the
desired position.
Impeller And Casing Installation
Warning: Failure to properly install the impeller
and impeller lock nut could result in the
impeller spinning off the shaft in three
phase applications (if motor starts in
reverse rotation).
Caution: Impeller may have sharp edges, hold
with a shop towel.
5) For ease of assembly lubricate the driving ring on
the mechanical seal with water. By hand, carefully
press the rotating seal assembly onto the motor shaft.
The carbon seal face must contact the ceramic seal
face. The driving ring must seal against the motor
shaft. Locate spring against retainer. Now, position
cup washer so end coil of spring fits inside cup wash-
er.
c) Align the bolt holes and secure the casing to the
bracket with (8) M6x16mm allen head bolts and
lock washers.
d) Cross tighten the bolts to 3.4 Ft. Lbs. (factory
recommended torque). Over tightening may result
in stripping the threads in the bracket.
8. Place mounting base on a flat surface. Screw sup-
port bolt/nut onto the base until bolt contacts the flat
surface. Two bolts are provided 1 3/4”L and 1 3/16”L.
Select the correct length to accommodate the motor
diameter.
9. Position the mounting base on the bracket (see
exploded view) and secure with (2) M8x16mm hex
head bolts. Tighten using a 13mm open end wrench.
Adjust the bolt height on the mounting base to sup-
port the motor and tighten the lock nut to secure its
position.
4. Make sure the cup washer has not become
trapped between the impeller hub and the shoulder of
the motor shaft during installation. Using a small tool
apply pressure against the cup washer to check for
movement.
5. Apply Loctite thread locker 242 to the exposed
threads on the motor shaft. Install the impeller lock
nut onto the shaft in the same manner as the impeller
was installed. Use a 11/16 socket wrench. Make cer-
tain the impeller nut is firmly sealed against the
impeller.

Final Inspection
After assembly, rotate the motor shaft. To do this, rotate the exposed motor shaft at the rear of the motor.
If you can turn the shaft with minimum effort and no drag, the pump is operable. If not repeat the impeller and
casing installation.
