FIGURE 2 Aligning Couplings
Check parallel adjustment by laying a straightedge
across both coupling rims at the top, bottom, and side.
When the straightedge rest evenly on both halves of
the coupling, the coupling is in horizontal parallel
alignment. If the coupling is misaligned, use a feeler
gauge between the coupling and the straightedge to
measure the amount of misalignment.
V-BELT DRIVES: V-Belt drives are not
recommended.
WARNING: Do not operate the pump without a guard
over the rotating parts. Exposed rotating parts can
catch clothing, fingers, or tools, causing severe injury
to personnel.
PUMP BEARING PEDESTAL: The shaft bearings
are permanently lubricated by the manufacturer and
sealed. Routine maintenance is not required.
POWER UNIT PREPARATION - ELECTRIC
MOTORS:
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
specification plate. 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 instructions for wiring for
counterclockwise rotation. Three phase motor rotation
may be reversed by inter-changing any two of the
three power leads. Make certain that wiring for your
electric motor complies with all existing local codes.
POWER UNIT PREPARATION - GASOLINE ENGINE
DRIVEN PUMPS:
For complete operating and
maintenance information consult the engine
manufacturer’s instructions included with the pump.
Before starting, fill crankcase with oil specified by the
engine manufacturer.
CAUTION: Always remove
spark plug or spark plug wire before working on unit to
prevent accidental starting.
PUMP OPERATION: This pump is self-priming, but
the pump should never be operated unless there is
liquid in the casing.
CAUTION: The pump will not
prime when dry. Operation of a dry pump will destroy
the seal assembly. Add liquid to the pump casing
when:
1. The pump is being put into service for the
first time. 2. The pump has not been used for a
considerable length of time. 3. The liquid in the pump
casing has evaporated. Once the pump casing has
been filled, the pump will prime and reprime as
necessary. To fill the pump, remove the pump casing
fill plug at the top of the casing and add clean liquid
until the pump is filled. Replace the fill plug before
operating the pump.
STARTING: Consult the operations manual furnished
with the power source. WARNING: Do not use pump
in explosive atmosphere. Do not pump volatile or
flammable liquids.
OPERATION: Open all valves in the discharge line
and start the power source. Priming is indicated by a
quieter operation. The pump may not prime
immediately because the suction line must first fill with
liquid. If the pump fails to prime within five minutes,
stop it and check the suction line for leaks. After the
pump has been primed, partially close the discharge
line throttling valve in order to fill the line slowly and
guard against excessive shock pressure which could
damage the pump, pipe, gaskets, sprinkler heads, and
any other fixtures connected to the line. When the
discharge line is completely filled, adjust the throttling
valve to the required flow rate. No leakage should be
visible at pump mating surfaces, or at pump
connections or fittings.
LIQUID TEMPERATURE AND OVERHEATING: The
maximum liquid temperature for this pump is 160
degrees Fahrenheit. Do not apply it at a higher
operating temperature. Overheating can occur if
operated with the valves in the suction and discharge
lines closed. Operating against closed valves could
bring the liquid to a boil, build pressure, and cause the
pump to rupture or explode. If overheating occurs,
stop the pump and allow it to cool before servicing it.
Refill the pump casing with cool liquid.
STOPPING: Never halt the flow of liquid suddenly. If
the liquid being pumped is stopped abruptly,
damaging shock waves can be transmitted to the
pump and piping system. Close all connecting valves
slowly. After stopping the pump, lock out the power
supply to ensure that the pump will remain inoperative.
Flush out the pump if the liquid being pumped will
leave a sticky residue or will harden.
DRAINING: During freezing weather, be sure to drain
the pump when it is not in use. Unscrew the drain plug
and run engine or motor about half a minute without
pumping.
STORAGE: When the pump is out of service for long
periods, drain it and store in a dry, well-ventilated
room. Pull the engine hard against compression so
that the valves will be sealed. (Never run pump dry for
more than half a minute or the shaft seal may be
damaged.)
