8. PROBLEM GUIDE
BREAKDOWN
The tank is full. The pump is
working, but the liquid does not go
out through the automatic nozzle.
The pump works, but no fluid
comes out.
The pump is working, but no liquid
goes out.
The motors sounds, but it does not
work.
Low flow
The pump works slowly and with
strange noises.
The motor stops.
The motor heats in excess.
The motor does not start.
Liquid loss
IRON-50 Ex BATTERY INSTRUCTION MANUAL
POSSIBLE CAUSE
- there is created an air chamber in the
delivery line, and the automatic nozzle
cannot be opened.
- problem in suction line
- opened bypass valve
- retainer leak
- blocked outlet pipe, nozzle or filter
- motor breakdown. The rotor must turn
anticlockwise, looking at the pump from
the heading; if not, return it for repairing
- blade friction
- problem in the suction line
- opened bypass valve
- blade friction
- mechanical seal loss
- roller or blade wear
- blocked outlet tuber or nozzle
- motor breakdown
- dirt on pump cavity
- motor breakdown
- too dirt on the filter
- problem in the suction line
- the bypass is blocked.
- blade friction
- roller or blade wear
- dirt on the red adapter
- wrong voltage
- motor breakdown
- low voltage
- solid impurities in the pump inner
- high viscosity fluid pumping
- blocked filter
- narrow suction/delivery tube
- motor breakdown
- there is no electricity.
- motor breakdown
-
switch

not
connected
- joint in bad state
- mechanical seal in bad state
MANUAL DE INSTRUCCIONES
- 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.
- check loss in suction line.
- remove and check the valve.
- change the retainer.
- check whether the pump outlet pipe, the hose, the nozzle and the
filter are blocked or not.
- verify the polarity in the connection.
- verify blades to see whether these are worn out.
- check leakages on the suction line.
- remove and check the valve.
- check the blades and grooves to see whether there are notches or
wear.
- tighten cover or change the mechanical seal.
- check the roller and blades to see whether there is a wear or damage,
and replace them.
- check the outlet pump tube, the hose, the nozzle and the filter mesh to
see whether these are blocked.
- the rotor must turn anti- clockwise, looking at the pump by the
heading; if not, return it for repairing.
- clean the pump cavity inner.
- return for its repair to the factory.
- dismantle and clean the filter.
- check the suction line to see whether there are leakages or
restrictions; it can be too narrow, too long or no hermetic.
- remove and check the bypass valve. Clean it.
- check the blades and grooves to see whether there are notches or
wear.
- check the roller and blades to see whether there is a wear or damage,
and replace them.
- clean the inner sieve.
- check the inlet line voltage.
- return for its repair to the factory.
- check the inlet line voltage.
- dismantle and clean the pump.
- these fluids only can be pumped for a short period.
- remove and clean the filter.
- replace tube.
- return for its repair to the factory.
- check the supply inlet system.
- return for its repair to the factory.

/
- adjust the switch connection / connect.
- check all the joints.
- replace the mechanical seal.
