•Maximum Liquid Temperature: 160ºF (71ºC)

•Maximum Starts per Hour: 20 – evenly distributed

Piping

• Pump MUST be installed horizontally on a solid flat

surface, with discharge on top.

NOTICE: Indicates special instructions which are very important and must be followed.

THIS MANUAL IS INTENDED TO ASSIST IN THE INSTALLATION AND OPERATION OF THIS UNIT AND MUST BE KEPT WITH THE PUMP.

THOROUGHLY REVIEW ALL INSTRUCTIONS AND WARNINGS PRIOR TO PERFORMING ANY WORK ON THIS PUMP.

MAINTAIN ALL SAFETY DECALS.

NOTICE:INSPECT UNIT FOR DAMAGE AND REPORT ALL DAMAGE TO THE CARRIER OR DEALER IMMEDIATELY. DO NOT USE PUMP IF DAMAGE IS SUSPECTED.

• Allow adequate space for servicing and ventilation.

Protect the unit from weather and water damage due to

rain or flooding or freezing temperatures.

• Piping should be no smaller than the suction and

discharge connections and kept short as possible,

avoiding unnecessary fittings to minimize friction losses.

• All piping MUST be independently supported and

MUST NOT place any piping loads on the pump.

NOTICE: DO NOT FORCE PIPING INTO PLACE AT PUMP SUCTION AND DISCHARGE CONNECTIONS.

• All pipe joints MUST be airtight.

• The use of TeflonTM tape, or equivalent, is recommended

WARNING

Hazardous Fluids

can cause fire,

burns or death.

UNITS NOT DESIGNED FOR USE WITH HAZARDOUS LIQUIDS OR FLAMMABLE GASES.

for ALL pipe joints.

SUCTION

•Total suction lift, including elevation and pipe friction loss, should not exceed 25 feet of head.

•Install an airtight union in the suction line close to the pump. See Figure 1.

•Installation of a foot valve at liquid source is recommended.

Description and Specifications

•The Model GT embraces a line of end suction, single stage, self-priming centrifugal pumps for lawn sprinkling, HVAC systems, and general water transfer.

•Casing is cast iron construction with tapped openings provided for vacuum gauge and casing drain.

•Impellers are enclosed design, glass filled NorylTM, threaded directly on motor shaft.

•Standard motors are NEMA standard, 3500 RPM, open drip proof enclosure.

NOTICE: FOR INSTALLATIONS WITH LONG SUCTION PIPING, BOTH A FOOT VALVE AND A CHECK VALVE ARE RECOMMENDED.

•To avoid air pockets, no part of the piping should be above the pump suction connection and piping should slope upward from liquid source.

•For installations with long suction piping, fill the suction pipe with water before connecting to pump.
