MAINTENANCE
a)
ENGINE:
Refer to the engine manufacturer's instructions for any
maintenance requirements.
b)
DRAINING:
If the pump is subject to freezing temperatures, drain
it by removing the drain plug and priming plug. After the water
has drained, run the pump for a few seconds to get the last of
the water out of the casing. Make sure the suction and discharge
lines are free of water.
WARNING:
Store the pump in a well-ventilated area, away from heat, flame,
or sparks.
TROUBLESHOOTING
*1)
Excessive suction lift must take into consideration:
a)
Size and length of pipe
b)
Pipe fitting
c)
Elevation above sea level
Including all of the above, we recommend that the total suction head
not exceed 25 ft.
*2)
An excessively worn impeller is mainly caused from cavitation,
which is caused by a number of situations, such as:
a)
Restricted suction
b)
Excessive suction lift
*3)
The seal may be damaged due to:
a)
Normal wear
b)
Overheating
c)
Pumping chemicals that this seal is not designed for.
Contact an authorized service depot for further assistance.
PROBLEMS
CAUSES
SOLUTIONS
Pump will not pump
Air leak in suction line.
Make sure suction hose is double clamped at joints, clamps are
tight, fittings have thread compound and are tight, with no nicks
or cuts in hose.
The suction and/or discharge line(s) may be blocked, or the
valve(s) are closed, faulty and/or blocked.
Check to see that the lines and valves are in good working order.
The end of the suction line is not submerged.
Increase its length, or move pump closer to source of liquid.
Total head is too high for this pump to work against.
Reduce total head or use a higher head pump.
Pump will not prime
Excessive suction lift (*1).
Move the pump closer to liquid source.
Priming takes a
long time
Suction line is quite long.
Refer to START-UP under OPERATION.
Air pockets or leaks in the suction line.
Check the line for loose connections.
Pump does not
perform as well as
it should
Flow is restricted due to:
a) Debris build-up.
b) Faulty or semi-open valve(s).
c) Pipe or hose used is smaller than the thread sizes on the pump.
a) Clean the lines and fittings.
b) Check to see that the valves are in good working order.
c) Increase the size of hose or pipe to reduce friction losses.
Insufficient submergence of the end of suction line.
The end of the suction line must be submerged.
Excessively worn impeller (*2).
Replace impeller.
Seal is damaged (*3). Liquid will be leaking through the middle
of the adapter.
Replace the seal.
Air pockets or leaks in the suction line.
Check suction line.
Clogged impeller.
Remove casing to clean out.
Pump loses prime
Water level drops below the end of the suction line.
Increase length of suction line or move the pump closer to the
water source.
Pump will not start
No fuel.
Add fuel.
Faulty spark plug.
Replace spark plug.
Pump will not start,
or starts but runs
roughly
Low oil level.
Fill crank case to the proper level.
Place pump on a flat, level surface.
Choke in wrong position.
Adjust choke.
Spark plug wire loose.
Attach wire to spark plug.
Pump shuts down
during operation
No fuel.
Add fuel.
Low oil level.
Fill crank case to the proper level.
Place pump on a flat, level surface.
