CHANGING ROTATION

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.

8200 Series centrifugal pumps can be operated clockwise or counterclockwise when viewed from the coupling end of the pump. If you wish to reverse the suction and discharge nozzles; i.e., change rotation, this can be accomplished with the same pump as follows:

1.Remove the impeller from the shaft, and relocate the two impellers per Figure 10 for the desired rotation. (Follow the disassembly procedures given in this manual.)

2.With the rotating element out of the casing, remove the casing from the base and turn 180°. (Factory bases are drilled for both rotations.)

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. The suction and discharge are offset, so the piping will need to be changed to accommodate the new flange locations.

4.Reassemble the 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.
