OPERATING & MAINTENANCE INSTRUCTIONS

FOR

MODEL GTU END SUCTION CENTRIFUGAL PUMPS

The Thrush End Suction Centrifugal Pumps has been carefully assembled and factory tested

to provide years of trouble-free service. In order to insure the service intended, the following

information is provided to enable proper installation, operation, and maintenance of this

product.

Location

The pump 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 motor.

Adequate provisions should be made for electrical wiring to the pump motor. A switch should be

installed near the pump to facilitate service. Single phase motors are provided with built-in overload

protection. Three phase motors must be protected externally. The electrical conduit should be

positioned in such a way as to preclude the possibility of moisture entering the conduit or the motor

and causing short circuits.

Piping

Piping practices directly affect the efficiency and power consumption of pumps. Pay particular

attention to the seemingly insignificant details involved in piping. They make the difference between

a good and a bad installation. BOTH THE SUCTION AND THE DISCHARGE PIPING SHOULD BE

INDEPENDENTLY SUPPORTED NEAR THE PUMP. LIBERAL USE OF PIPE HANGERS AND

SUPPORT BLOCKS WILL PREVENT EXCESSIVE STRAIN ON THE PUMP CASING AND ON

THE PIPE JOINTS. IT IS ESSENTIAL THAT PIPING BE PROPERLY ALIGNED BEFORE

CONNECTION IS MADE. PIPING ALIGNMENT SHOULD NEVER BE ACHIEVED BY FORCE.

THIS COULD PRODUCE STRAIN ON THE PIPING AND THE PUMP CASING.
