OPERATION & MAINTENANCE INFORMATION
FOR
MODEL GT & GTB IN-LINE CENTRIFUGAL PUMPS
AND MP PUMPS
MODEL GT & GTB
The Thrush In-Line Centrifugal Pump has been carefully assembled and factory tested to provide
years of trouble-free service. In order to assure the service intended, the following information is
provided to enable proper installation, operation and maintenance of the GT / GTB pump.
MODEL MP PUMP
The Thrush MP pump uses standard GTB replacement parts for easy parts replacement. The motor
and bearing assembly have sealed ball bearings and never have to be oiled or greased. The motor is
also resilient mounted for reliable quiet operation. The pump comes with the standard Type 21 seal,
stainless steel shaft and external water slinger for added bearing assembly life in case of seal failure.
Because of the universal machining of the bracket assembly, the Thrush Boiler Manifold Pump will
replace most models on the market today.
INSTALLATION
LOCATION
The pumps should be located as close to the liquid source as possible so that the suction line can be
short an direct. It should be located in a clean, open area, where it is easily accessible for inspection,
lubrication and repair. Pumps installed in dark, dirty areas or in cramped locations are often
neglected which can result in premature failure of both the pump and the drive.
Adequate provisions should be made for electrical wiring to the pump motor. A switch and overload
protection should be installed near the pump. The flexible electrical conduit should be used in
connecting motor wiring.
