BREAKDOWN PROBABLE CAUSES POSSIBLE SOLUTIONS
Pump does not supply
the required flow
- blocked filter - disassemble and clean (or replace)
- air intake in the suction tube - Check closure grip
-Collector leakage caused by fusion defect -Replace collector
- Breakage of coupling for pump-motor - Disassemble and replace
connection
- Damage to pump-collector connection gasket - Disassemble collector pump and replace
gasket
- Worn out pump - Replace
Pump does not supply
the right pressure
- Calibration error on pressure relief valve - Re-set required calibration
(calibration too low)
Pump does supply
the right pressure
- Worn out pump - Replace
- Insufficient motor power - Assemble more powerful motor
- Excessive loss of charge in circuit - Check for possible bottlenecks
or excessive oil viscosity
Pump does not supply
the right pressure
- Leakage from the valves - Check that the valves are tightened
Valve blockages
or leakages
- Leakage - check valve - Disassemble and blow
(replace if necessary)
- Electric seat valve leakage - Disassemble and blow
(replace if necessary)
- Electric valve excitation faulty - Check that the minimum required voltage is
reaching the bobin
Minimum required voltage
(90% of normal voltage)
- Blockage of slide valve caused by - Disassemble and blow
Dirt in the circuit (replace if necessay)
- Try to add filtering elements to the
circuit, to obtain better filtering (25 micron)
