CHANGING ROTATION

Series HSCS centrifugal pumps can be operated left hand or

right hand when viewed from the pump end of the pump. If

you wish to reverse the suction and discharge nozzles, this

can be accomplished with the same pump as follows:

IMPORTANT: Refer to the disassembly and assembly proce-

dures section of this manual for proper disassembly and

assembly techniques:

1. Remove the impeller from the shaft, turn it 180° and replace

it on the shaft. (Follow the disassembly procedures given in

this manual.)

2.With the rotating element out of the casing, remove the

casing from the bedplate and turn 180°.

3. Set the rotating element back in the casing and reassemble

the pump.

NOTE: The impeller and casing are in the same relationship

to each other as they were originally. The shaft and motor

are also in the same relationship to each other as they were

originally.

4. Reassemble pump and realign the coupling as called for in

the alignment instructions.

5. The rotation of the motor must be changed by switching the

motor leads.

NOTE: Unless the motor rotation is reversed, the impeller

will run backward.

WARNING: Rotating Components Hazard

Do not operate pump without all guards in place.

Failure to follow these instructions could result in serious

personal injury or death and property damage.
