CHANGING ROT ATION
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:
IMPOR TANT:
Refer to the disassembly and assembly pr oce-
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 ar
e 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 r otation is reversed, the impeller
will run backward.
W ARNING: Rotating Components Hazard
Do not operate pump without all guar ds in place.
Failure to follow these instructions could result in serious
personal injury or death and property damage.
