OPERATING AND MAINTENANCE INSTRUCTIONS

FOR PC/E-300 & PC2G CLOSE-COUPLED END

SUCTION CENTRIFUGAL PUMPS

The THRUSH End Suction Centrifugal Pump 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.

INSTALLATION

LOCATION

The pump should be located as close to the liquid source as possible so that the suction line can

be short and 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 driver.

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

overload protection should be installed near the pump unless it is impractical. 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.

FOUNDATION

The foundation must be sufficiently rigid to absorb any vibration and stress encountered during

pump operation. A raised foundation of concrete is preferable for most floor-mounted pumps.

The raised foundation assures a satisfactory base, protects against flooding, simplifies moisture

drainage and facilitates keeping the area clean.

The pump should be firmly bolted to the foundation, whether it is a raised concrete base, steel

work wall, or structural member. The mounting bolts or studs should be accurately located per

the applicable THRUSH dimension sheet. Foundation bolts should be enclosed by a sleeve 2 to

4 diameter larger than the bolt to allow movement for proper alignment with the pump mounting

holes. Refer to Figure 1. If the pump is to be mounted on steel work or other structure, adequate

support should be provided to the base plate or the structure could produce excessive strain on

the pump casing and piping and seriously affect alignment of the pump and driver.
