Periodic maintenance and inspection is required on all pumps to ensure proper operation. Unit must be clear of debris and sediment. Inspect for leaks and loose bolts. Failure
to do so voids warranty.
Patterson/AMT Inline Circulator Pump
Refer to pump manual 1808-634-00 for General Operating and Safety Instructions.
DESCRIPTION
Patterson/AMT Inline Circulator Pumps are designed for continuous duty industrial/commercial applications. Pumps are designed for liquid circulation in
HVAC and industrial/commercial systems. Pumps are available in cast iron or bronze configurations to meet your specification. Pump casing is equipped
with
⅛” NPT suction and discharge gauge ports. Pumps are powered by a 56C NEMA frame electric motor with ½” conduit connection. Pump is
equipped with precision lapped mechanical shaft seal to reduce the likelihood of leakage, O-ring sealed casing and a bronze impeller. Liquid range is
40̊
to 200̊ F (4̊ to 93̊ C). Liquid viscosity and specific gravity must be close to water; 31 SSU and 1.00 SG. Maximum casing pressure is 150 psi. Pump
shipped with NPT flanges, flange gaskets and flange installation hardware.
All single phase motors are equipped with automatic thermal protection. Overload protection is recommended for three phase motors, but is not
supplied. Check motor wiring before putting unit into service (see motor nameplate for specific wiring diagram). These are manual units. No controls are
supplied.
All units are for use with non-flammable, non-abrasive liquids
compatible with pump component materials.
IMPORTANT: Not for use with petroleum based
liquids.

UNPACKING
Refer to Repair Parts Illustration and Repair Parts List to aid in
identifying parts. Unpack and separate all pump components from
shipping/packaging materials, making sure all parts are accounted for.
Retain all manuals for reference. Package should contain: pump,
flanges, circulator pump specific manual and general pump manual.
INSTALLATION
1.
Pump is designed for circulating liquid in a closed system for
a flooded suction application. Pump will not self-prime.
2.
Piping system must be designed for adequate thermal
expansion.
3.
A pressure relief valve should be considered to protect pump
casing from over pressurization and pressure spikes,
especially if a check value is installed near pump.
4.
Locate the pump so that there is sufficient room for
maintenance and servicing.
5.
There must be a sufficient supply of cooling air and
ventilation around the pump and motor to avoid excessive
component temperatures.
6.
Installing a shutoff valve in both the suction and discharge
piping will make removal and servicing of the pump possible
without draining the entire system.
7.
Support the piping near the pump’s suction and discharge
with sufficient piping hangers. This will minimize pipe strain.
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).
8.
Make sure bolt holes in pipe flange line up with bolt holes in
pump flange.
Do not spring the suction or discharge piping into position. This
will result in excessive stain in the piping, flanges and pump
casing.
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.
