EQ Series Pump Installation and User’s Guide
Assembly
1. Ensure that the two 6 ½ in. long screws (11) with washers (12) are properly inserted into the bottom of the
motor adaptor (7) before attaching the motor adaptor (7) to the new motor (1).
2. Properly orient the motor adaptor (7) to the motor (1) and secure in place using the four screws (10) and
washers (8) (9).
3. Insert the two dowel pins (26) into the motor adaptor (7).
4. Install the stationary ring of the mechanical seal (14) into the seal plate bore. Ensure that it is fully inserted into
the bore with the white surface facing you.
CAUTION — The mechanical seal is a highly engineered component that must be carefully handled. The contact
faces are manufactured to extremely precise tolerances. These faces must be free of all surface dust
and debris. Always wash your hands before handling the mechanical seal. Avoid touching the
contact faces except for when pressing the seal ring into the bore. Lubricate the rubber portion with
a slight amount of soapy water if required to insert it into the bore. Do not use silicone or other
lubricants as this can contaminate the seal face. Rinse the seal face if required after assembly to free
it of any dirt or debris.
5. Properly orient the seal plate (13), slip it onto the two dowel pins (26) and secure to the motor adaptor (7) by
tapping it toward the motor adaptor (7) until there is no clearance between the two parts.
6. Slip the spring portion of the mechanical seal (14) over the motor shaft, being certain that the hard black
contact surface is facing the white surface of the stationary seal ring. Use a small amount of soapy water if
required to lubricate the rubber of the mechanical seal (14) so that it slips easily over the shaft.
7. Install the shaft key into the shaft of the motor and then install the impeller (15) over the shaft. It will be
necessary to align the keyway in the impeller (15) with the key . Push the impeller (15) as far as possible
onto the motor shaft (1).
8. Install the socket head screw (16) with washers (4) (5) to secure the impeller (15). It is important that the
screw (16) be tightened securely and that the impeller (15) is fully seated.
9. Apply a light film of silicone grease to the inside diameter of the brass bushing inside the diffuser (17). This
film will assist in properly centering the diffuser bushing to the impeller (15) and will reduce the friction should
the parts contact during motor start-up. DO NOT USE ANY OTHER TYPES OF LUBRICANTS.
10. Install the diffuser (17) over the impeller (15) and secure with the four screws (20), but only hand tight. The
diffuser (17) has clearance around the four screws (20) that will allow adjustment of the fit of the diffuser (17)
around the impeller (15) nose. Rotate the impeller (15) by hand to ensure that it is free to turn and slowly tighten
each of the four screws (20). Verify that the impeller (15) is free to turn once the diffuser screws (20) are fully
tightened.
11. Lubricate the diffuser O-Ring (21) and the larger seal plate O-Ring (28) with silicone lubricant or Murphy ® Oil
Soap. This will allow the O-Rings to slip into place without getting pinched. Ensure that the big seal plate
O-Ring (28) is properly seated on the large diameter of the seal plate (13).
12. Carefully slip the motor end assembly into the housing (22) pushing it forward as far as possible until the large
seal plate O-Ring (28) comes into contact with the housing (22). Insert the four 6½ in. long screws (11) through
the housing (22) and secure the assembly in place using the washers (12) and nuts (23). Gradually tighten each
of the four screws a few turns in a crossing pattern to ensure that the motor assembly is properly centered to
the housing.
Do not over tighten these screws.
CAUTION — Failure to follow the above assembly procedures could cause the impeller to bind once the pump is
fully assembled. It is possible to remove the strainer basket, reach through the strainer pot and spin
the impeller to verify that it will rotate freely. A bound impeller may cause the motor to not start or
cause the motor to draw excessive amps.
13. Secure the motor (1) to the motor supports (2).
14. Reconnect the ground and supply conductors.
15. Read and follow the instructions under Section 4, Initial Operation of Pump before putting the pump back into service.
