PROBLEM GUIDE
BREAKDOWN POSSIBLE
CAUSE
SOLUTION
The tank is full. The pump is
working, but the liquid does not go
out through the automatic nozzle.
- There is created an air chamber in the
delivery line, and the automatic nozzle
cannot be opened.
- remove the automatic nozzle from the hose. Start the pump until it is
primed, and the liquid automatically goes out. Then install again the
automatic nozzle.
The pump works, but no fluid
comes out.
- problem in suction line
- opened bypass valve
- blade friction
- retainer leak
- blade or roller wear
- blocked outlet pipe or nozzle
- motor breakdown
- check loss in suction line.
- remove and check the valve.
- verify blades to see whether these are worn out.
- change the retainer.
- check roller and blades whether they are worn out, and replace them
- check whether the pump outlet pipe, the hose, the nozzle and the filter
are blocked or not.
- the rotor must turn anticlockwise, looking at the pump from the heading;
if not, return it for repairing
The pump makes noise, but it
does not work.
- dirt inside the pump, blade friction
- motor breakdown
- clean pump inside.
- return for repairing to the factory.
Low flow rate
- excess of dirt in filter
- problem in suction line or in delivery
- the bypass is blocked.
- blade friction
- blade or roller wear
- dirtiness on the red adaptor
- disassemble and clean the filter.
- verify suction line to check whether there are leakages or restrictions,
or not; it may be too narrow, too long or no hermetic.
- remove and check bypass valve. Clean it.
- verify blades to see whether these are worn out.
- verify blades and roller whether these are worn out or there is
something wrong, and replace them.
- clean the inner sieve.
The pump works slowly making
strange noise.
- wrong voltage current
- motor breakdown
- verify inlet voltage.
- return for repairing to the factory.
The motor stops or is burning.
- low voltage current
- solid impurities inside the pump
- verify inlet voltage.
- disassemble and clean the pump.
The motor heats up excessively.
- it pumps high viscosity fluids.
- blocked filter
- narrow suction/delivery tube
- motor breakdown
- these fluids only can be pumped for a short period.
- remove and clean filter.
- replace with an adequate tube.
- return for repairing to the factory.
The motor does not start.
- there is no electricity.
- motor breakdown
- switch connection not lined up /
connected
- verify inlet current.
- return for repairing to the factory.
- adjust connection switch/connect.
Leak of liquid
- connection joint in bad state
- mechanical seal in bad state
- verify all connection joints.
- replace the mechanic seal.
