ORIENTING PUMP
1. The pump can be oriented in any desired position: discharge up or down,
left or right.
2. If motor is oriented vertically up, a means of venting air from the seal
chamber must be installed in the seal plate (Ref. No. 8) 1/8” NPT port.
Remove 1/8” NPT plug (Ref. No. 6) and install air venting device or liquid
injection line.
3. DO NOT INSTALL UNIT with motor vertically down, any liquid breaching
the mechanical shaft seal will run directly down shaft into motor.
NOTE: Proper motor support is required to avoid damage to pump or motor.
Use correct size motor hanger similar to the one pictured based on model
being installed. Hangers vary depending on horizontal or vertical installation
(see figure 1).
INSTALLING FLANGES
1. Included with pump: (2) 3” NPT flanges, 2 gaskets, and 4 bolts, nuts, and
washers.
2. Install flanges on piping using sealing tape or pipe sealant.
3. Insert gasket into machined groove on pump flange.
4. Position pump by lining up bolt holes on pump flange with bolt holes on
pipe flange.
5. Install 4 hex head bolts, nuts, and washers with thread sealant (Vibra-Tite
(12150) Threadlocker Medium Strength Removable).
6. Torque both flange bolts in even increments to a value of 8-11 ft-lbs (1.1-
1.5 Kg-m). Torque the bolts in both the suction and discharge flanges in
this manner.
OPERATION
1. Prior to pump start up, be sure system is clean and filled with clean liquid
that is compatible with pump components.
2. Pressure the pump body slowly. Check for leaks at the flange joint, the
pump casing and motor shaft.
Pressurize pump casing slowly. Failure to check for leaks at all joints
sealed with a gasket may result in personal injury or property damage.
Installation of a collection pan and/or drain is required to prevent property
damage from system leaks.
3. DO NOT RUN PUMP DRY! Mechanical shaft seal damage will occur
if pump is run dry. Pump body must be filled with liquid before starting
motor. Air must be vented from the system by means of an air vent located
at a high point in the system.
MAINTENANCE
Make certain that the unit is disconnected and locked out from the power
source before attempting to service or remove any components.
1. System must be drained or pump isolated by turning off suction and
discharge valves before attempting to remove pump.
Patterson/AMT Inline Circulator Pumps
Water temperature in system cannot exceed 90̊ F (32̊ C) before removing
or servicing pump. If draining system, leave drain valve open during
servicing.
Pump surface temperature cannot exceed 90̊ F (32̊ C) before removing or
servicing pump.
Loosen flange bolts slightly and shift pump side to side to vent internal
pump casing pressure before removing or servicing pump.
2. Remove pump from the system by removing eight flange mounting bolts,
nuts and washers (Ref. Nos. 18 & 19).
SHAFT SEAL REPLACEMENT
Refer to Figure No. 2 for part identification. Order Ref. No. 13A to replace all
seals and o-rings.
REMOVAL OF OLD SEAL
IMPORTANT: Always replace both seal seat (Ref. No. 10) and seal head
(Ref. No. 11) to ensure proper mating of components. Also, impeller seal (Ref.
No. 13) should be replaced anytime impeller fastener (Ref. No. 14) has been
removed.
1. Remove fasteners (Ref. No. 5) connecting casing (Ref. No. 15) to adapter
(Ref. No. 7).
2. Slide casing off of adapter locating boss. Take care when removing
casing, it may be heavy.
Care should be taken not to pinch or “shave” casing o-ring (Ref. No. 9)
between seal plate (Ref. No. 8) and casing.
3. Use a box wrench and/or socket wrench to remove impeller fastener.
Remove impeller seal and impeller (Ref. No. 12).
NOTE: Stub shaft must be held in place to remove impeller. Insert a hex key
through adapter opening into one of the screws fastening shaft clamp (Ref. No.
2) to motor/stub shaft. Brace hex key against side of adapter opening. Impeller
and impeller fastener unscrew CCW when looking at the impeller eye.
4. Disconnect any piping or venting apparatus attached to seal plate 1/8”
NPT wash/vent port.
5. The seal head can now be pulled from shaft. Remove seal plate (Ref. No.
8) from adapter.
6. Pry seal seat from cavity in seal plate.
