Engine-Driven Centrifugal Pumps
5.
A suitable suction strainer should be attached to the suction line so
that large pieces of foreign material are not drawn into the pump. The
maximum opening in the suction strainer should not be greater than 25%
of the suction inlet size for solid handling pumps and 50% of the suction
inlet size for trash pumps.
OPERATION
1.
OIL: Fill the engine crankcase with oil as specified in the engine manual.
Periodically check oil level thereafter and service stated in engine
manual.
2.
FUEL: Fill the fuel tank as required for engines. Refer to engine instruc-
tion booklet for proper fuel type.
3.
OTHER: Fill any other required fluid such as antifreeze, etc. (if required
by engine manufacturer).
Never add gasoline to a hot engine! See General Safety Information for
proper handling of gasoline.
4.
Fill the pump with liquid through the pump priming port supplied with
these units. The pump should prime and re-prime without refilling. Refill-
ing is necessary occasionally if an unusual siphoning has occurred, if the
fluid has been lost by evaporation, and when the unit is moved to a new
location.
Do not run pump dry, as permanent damage to the mechanical seal will
result.
5.
Start the engine, following instructions in the engine manual.
6.
With a suction lift of 5 to 10 feet, the pump should discharge liquid within
one or two minutes. A suction lift of 20 feet can take 5 minutes of running
time to pick up a prime. If pumping does not start within this time, shut
off the engine, let unit cool down about 5 minutes, refill pump casing and
retry. If engine does not start, refer to Engine Manual. If pump does not
prime after two tries, refer to "Troubleshooting Chart" in this manual.
7.
Properly fueled and lubricated, the pump/engine unit will run automati-
cally without attention to the controls. The gasoline engine has a built-in
governor and will adjust the speed of the engine automatically depending
on the volume of water being delivered.
Even though this unit will operate with minimal supervision, it should
not be left operating by itself. Depending on the application and area
unit is operating (high traffic, people in area, etc.) will dictate the neces-
sity of having someone watching over the unit.
MAINTENANCE
NOTE: Always flush pump thoroughly after use or if unit is not going to be used
for any prolonged length of time to prevent crystallization and/or damage to
seal and pump.
ROUTINE
1.
Pump should be drained when subjected to freezing temperatures. A drain
plug is provided on the pump casing.
800-350-8739
2.
Clean the suction line strainer at regular intervals.
3.
If the engine is equipped with a spark arrestor screen in the muffler, it
should be inspected for wear periodically and replaced when necessary
NOTE: For information pertaining to the engine and engine parts, consult the
Engine Manual or contact the nearest authorized service representative or the
manufacturer.
4.
Periodically check nuts and bolts on engine, mounting frame and pump.
Since this is a gas engine pump, vibration levels tend to loosen nuts and
bolts faster than normal. Use Loctite (thread sealant) on threads or lock
washers if necessary.
