Patterson/AMT Inline Circulator Pump
10.
Place casing seal on seal plate raised boss. Slide casing onto
seal plate and adapter.
11.
Attach casing using fasteners with thread sealant applied
(Vibra-Tite
(12150)
Threadlocker
Medium
Strength
Removable). Spin motor shaft to check for interference with
casing.
Seal will produce minor drag when spinning motor shaft, but
rubbing anywhere else must be eliminated! Otherwise, damage to
pump and/or motor may occur.
MOTOR REPLACEMENT
Entire pump end must be disassembled before removing motor
from adapter and stub shaft.
1.
Remove pump casing, impeller, shaft seal, and seal plate as
described in SHAFT SEAL REPLACEMENT section.
2.
Remove fasteners (Ref. No. 5) connecting adapter (Ref. No.
7) to motor (Ref. No. 1).
3.
Remove adapter from motor.
4.
Loosen fasteners of shaft clamp (Ref. No. 2). Remove shaft
clamp, stub shaft (Ref. No. 4), and drive key (Ref. No. 3) from
motor shaft.
5.
Reverse procedure, reassemble pump on replacement motor.
6.
Set distance from motor end bell mounting face to stub shaft
shoulder (at base of impeller threads) to 2.75”.
7.
Securely tighten shaft clamp fasteners locking stub shaft in
position
.
PUMP PIPING
1.
Proper system design and installation by a qualified engineer
is recommended.
2.
Always start piping from pump.
3.
Use as few bends as possible and preferably long radius
elbows.
4.
Do not use flexible connectors on the suction or discharge of
a vertical in-line pump unless the pump is rigidly mounted to a
foundation.
5.
Ensure piping exerts no strain on pump as this could distort
the casing causing breakage or early failure due to pump
misalignment.
6.
All connecting pipe flanges must be square to the pipe work
and parallel to the pump flanges.
7.
Eliminate all air pockets that may prevent the pump from
operating effectively.
8.
In open systems, test suction line for air leaks before starting;
this becomes essential with long suction line or static lift.
9.
Install valves in both suction and discharge lines to assist with
pump inspection or repair. Suction line valve may be opened
completely during operation.
10.
Install a non-slam non-return check valve in discharge line
between pump and isolation valve to protect pump from
excessive back pressure and to prevent water running back
through the pump on open systems.
11.
Before starting pump, the system must be thoroughly
cleaned, flushed and drained and replenished with clean
liquid.
12.
Welding slag and other foreign materials, improper or
excessive water treatment are all detrimental to the pump
internals and sealing arrangement and void warranty.
13.
Proper operation cannot be guaranteed if the above
conditions are not adhered to.
NOTE:
INSPECT THE FOLLOWING BEFORE PUTTING PUMP INTO
OPERATION:
1.
Pump primed; liquid in pump.
2.
Rotation.
3.
System piping and pump properly supported.
4.
System clean of all debris.
5.
Proper electrical connections. Consult qualified
electrician with any questions.
6.
Proper motor support is required to avoid damage
to motor or pump see page 1, Installation &
orienting sections
IMPORTANT: SYSTEM MUST BE FREE OF ALL PETROLEUM
BASED LIQUID OR SUBSTANCE TO AVOID SEAL FAILURE,
WHICH CAN ALSO LEAD TO PREMATURE MOTOR BEARING
FAILURE. FAILURE TO COMPLY VOIDS WARRANTY.
