PROBLEMS

Air leak in suction line.
The suction and/or discharge line(s) may be blocked, or the
valve(s) are closed, faulty and/or blocked.
The end of the suction line is not submerged.
Total head is too high for this pump to work against.
Pump will not prime Excessive suction lift (*1).

*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)
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

MAINTENANCE
3
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.
Check to see that the lines and valves are in good working order.
Increase its length, or move pump closer to source of liquid.
Reduce total head or use a higher head pump.
Move the pump closer to liquid source.
Refer to START-UP under OPERATION.
Check the line for loose connections.
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.
The end of the suction line must be submerged.
Replace impeller.
Replace the seal.
Check suction line.
Remove casing to clean out.
Increase length of suction line or move the pump closer to the
water source.
Add fuel.
Replace spark plug.
Fill crank case to the proper level.
Place pump on a flat, level surface.
Adjust choke.
Attach wire to spark plug.
Add fuel.
Fill crank case to the proper level.
Place pump on a flat, level surface.
a) Restricted suction
b) Excessive suction lift
a) Normal wear
b) Overheating
c) Pumping chemicals that this seal is not designed for.
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.
