Please read and save this Repair Parts Manual. Read this manual and the General Operating Instructions carefully before attempting to assemble, install, operate

or maintain the product described. Protect yourself and others by observing all safety information. The Safety Instructions are contained in the General Operating

Instructions. Failure to comply with the safety instructions accompanying this product could result in personal injury and/or property damage! Retain instructions

for future reference. AMT reserves the right to discontinue any model or change specifications at any time without incurring any obligation.

Periodic maintenance and inspection is required on all pumps to insure proper operation. Unit must be clear of debris and sediment. Inspect for leaks and loose bolts. Failure to do so

voids warranty.

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

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.

Locate the pump so that there is sufficient room for maintenance and

servicing.

There must be a sufficient supply of cooling air and ventilation around the

pump and motor to avoid excessive component temperatures.

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.

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 1.5” NPT

suction and discharge guage 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 closed impeller. Liquid temperature range is 40° to 200° F (4° to 93°

C). Liquid viscosity and specific gravity must be close to water; 31 SSU and 1.00. 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.

Figure 1 - Piping Hanger & Support

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).

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.
