TROUBLESHOOTING
*1) Excessive suction lift must take into consideration:
a) Size and length of pipe
b) Pipetting
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,ttings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ttings.
b) Check to see that the valves are in good working order.
c) Increase the size of hose or pipe to reduce friction losses.
Insufcient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.
Engine throttle is in SLOW position Move throttle to FAST position
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. Allowenginetocoolfor2minutes,thenllfueltank.
Faulty spark plug. Replace spark plug.
Fuel valve lever is in the OFF position Turn the fuel valve lever to the ON position.
Ignition switch is in the OFF position Turn the ignition switch to the ON position.
Choke is in the wrong position. Slide choke lever to the CHOKE position.
Pump starts, but
runs roughly
Choke is in the wrong position. Slide choke lever to the RUN position.
Spark plug wire is loose. Attach wire to spark plug securely.
Faulty spark plug. Replace spark plug.
Fuel is contaminated (water, debris, etc.) Allow engine to cool for 2 minutes, then drain fuel tank and
carburetor. Fill tank with fresh fuel.
Pump shuts down
during operation
No fuel. Allowenginetocoolfor2minutes,thenllfueltank.
