C. Power unit preparation - Electric Motors
1. Make certain the input power to your electric motor is proper,
single phase or three phase, and is of the proper voltage
according to the motor specication plate.
2. Be sure of the proper motor rotation. Pump impeller should
rotate counterclockwise, looking from the suction inlet side. For
single phase motors consult the motor manufacturer’s for wiring
for counterclockwise rotation. Three phase motor rotation may be
reversed by interchanging any two of the three power leads.
3. Make certain that wiring for your electric motor complies with all
existing codes.
D. Power unit preparation - Hydraulic and Pneumatic
motors:
Consult the separate instruction sheet supplied with each
hydraulic or pneumatic motor powered unit.
Power requirements:
NOTE: For liquids having specic gravities greater than 1.0,
increase the rated horsepower (from catalog) by a factor equal
to the specic gravity of the liquid being pumped. (Ex. Catalog
HP x Specic gravity = Actual HP required)

NOTE: Reducing pipe size will drastically reduce pump performance and can damage pump if overly restricted. The suction line should
always be the same size or larger than the discharge line. For optimum pump performance the pipe size should remain the same as the port
sizes.
IV. PUMP TROUBLESHOOTING AND REPAIR
DIAGNOSIS TREATMENT
1. Fill the pump with clean liquid and try pumping again.
2. Shut off power source to the pump. Shut off valves to and from
pump. While observing all safety precautions for the liquid being
pumped, disconnect suction and discharge lines and drain the
pump completely. Fill the pump with water. Install a vacuum
gauge in the suction port (See Figure #4). Turn on power source.
Vacuum should exceed 22 inches of mercury when pump shaft is
rotating at 3450 RPM and should equal or exceed 11 inches of
mercury with pump shaft at 1750 RPM. If vacuum
is below these values, check the following:
a. Leak at suction tting.
b. Pump rotation, impeller should rotate counter
clockwise when viewing through suction end.
c. Pump speed. (Maximum vacuum performance drops off
rapidly with decreasing RPM).
d. Sealing of check valve gasket between body and volute.
e. Check for worn impeller or volute. If necessary, replace these
parts. (See items B.5, B.6 and B.7 of section V)
f. Worn shaft seal.
3. If pump suction tests ok, attach suction line and check suction
at end of suction line. Failure to get suction here indicates leaking
connections, leaking hoses, pipes or obstruction in the lines.
Liners of suction hose will occasionally collapse inside the hose.
1. Check the items as in 1,2 and 3 above.
2. Replace any worn or broken components; check clearance
between impeller vanes and volute face (See section V #B.5).

E. When pumping dirty water or other liquids which may contain
solids, always use a pump strainer on the end of the suction line
specied by the manufacturer. If the suction strainer is likely to
clog with dirt and debris, do one of the following:
(a) Prepare a bed of rocks on which to rest the strainer. (See
Figure #3)
(b) Tie the strainer so that it stays off the bottom of the pit,
excavation, etc.
(c) Tie the strainer inside a basket or pail. (See Figure #3)
F. Drain the pump body whenever there is a dnager of freezing.
G. Always use rubber feet under portable pump when operating on
a hard surface. This will prevent damage to the pump and power
unit.
H. Always ush out the pump at the end of operation if the liquid
being pumped may leave a solid or sticky residue in the pump.
If this is not done, damage to the pump may result.
A. Fill the pump body with liquid before starting.
Do not run the pump dry; damage to the seal may result. There
are no points on the pump which need lubrication. The shaft seal
is self lubricating, and is designed to handle clean liquids.
B. Make certain that all hose and pipe connections are air tight.
IMPORTANT: An air leak in the suction line may prevent priming,
and will reduce the capacity of the pump.
C. Always place the pump as close as possible to the liquid to be
pumped. Keep all lines as short and straight as possible. Avoid
sharp bends in the hoses. Keep the pump on a level
foundation. See Figure #1.
D. If exible hosing must be laid across a roadway, protect it with
planking. Instantaneous shut-off pressures applied when a ve
hicle runs across an unprotected hose will cause “hydraulic
shock”. This shock can damage the pump and/or damage the
hose. See Figure #2.
