systems
Rotor jams Check for possible damage or obstruction of
the rotating components.
Motor problems Contact with the service department
Low or no flow rate Low level in the suction tank Refill the tank
Foot valve blocked Clean and/or replace the valve
Filter clogged Clean the filter
Excessive suction pressure Lower the pump with respect to the level
High loss of head in the circuit (working with
the by-pass open)
Use shorter tubing or of greater diameter
By-pass valve blocked Dismantle the valve, clean and/or replace it
Air entering the pump or the suction tubing Check the seals of the connections
A narrowing in the suction Tubing Use tubing suitable for working under suction
pressure
Low rotation speed Check the voltage at the pump. Adjust the
voltage and/or use cables of greater cross-
section
The suction tubing is resting on the bottom of
the tank
Raise the tubing
Increased pump noise
Cavitations occurring Reduce suction pressure
Irregular functioning of the by-pass Dispense until the air is purged from the
circuit
Air present in the diesel fuel Verify the suction connections
Leakage from the pump body Seal damaged Check and replace the mechanical seal
