In either case, proceed as follows:
- Close the delivery valve,
- Attach the end of the delivery to the slot provided on the tank (if available);
- Turn the switch to the OFF position;

5.5- Troubleshooting
PROBLEM
The motor is not turning
The motor turns slowly
when starting
Low or no flow rate
Increased pump noise
Leakage from pump body
POSSIBLE CAUSE
Lack of electric power
Rotor jammed
Motor problems
Low voltage in the electric
power line
Low level in suction tank
Foot valve blocked
Filter clogged
Excessive suction pressure
High loss of head in the delivery
circuit (working with the
by-pass open)
By-pass valve blocked
Air entering the pump or the
suction tubing
A narrowing in the suction
tubing
Low rotation speed
The suction tubing is resting on
the bottom of the tank
Cavitation occurring
Irregular functioning of the
by-pass
Air present in the diesel fuel
Seal damaged

CORRECTIVE ACTION

Check the electrical connections
Check for possible damage or
obstruction of the rotating components
Contact the service department
Bring the voltage back within the
anticipated limits
Refill the tank
Clean and/or replace the valve
Clean the filter
Lower the pump with respect to the level
of the tank or increase the cross section
of the tubing
Use shorter tubing or of greater diameter
Dismantle the valve, clean and/or replace
it
Check the seals of the connections
Use tubing suitable for working under
suction pressure
Check the voltage at the pump. Adjust
the voltage and/or use cables of greater
cross-section.
Raise the tubing
Reduce suction pressure
Dispense fuel until the air is purged from
the by-pass system
Verify the suction connections
Check and replace the seal
