Fault
Medium leaks above
the progressive cavity
pump
Medium leaks be-
tween clamp connec-
tions
Medium leaking
(mechanical seal)
No flow
Insufficient flow
Motor switches off
(Overload)
Motor running but
progressive cavity
pump does not pump
Motor running but
progressive cavity
pump does not pump
(Asynchronous mo-
tor)
Motor does not start
Progressive cavity
pump vibrates
strongly
Stator housing can-
not be completely
screwed onto pump
tube
110
Cause
Mechanical seal defective /
worn
Mechanical seal not posi-
tioned correctly on counter
ring
Seals on clamp connections
missing or defective
Clamp connection insuffi-
ciently tightened
Sliding ring not positioned
correctly on counter ring
Pump shaft broken
Stator or rotor heavily worn
Stator and rotor are not com-
patible
Counterpressure too high
Blockage
Pump shaft broken / rotor
blocked
Motor running in the wrong
direction. Due to the free-
wheel, the progressive cavity
pump cannot be driven in the
wrong direction
Motor was overloaded
Mains cable/plug defective
Progressive cavity pump is
running dry
Pump shaft is bent
Stator not correctly positioned
in stator housing
Help with faults
Measure
Replace the mechanical seal
Grease the shaft surface on the sliding
ring seat with suitable lubricant
Switch off the progressive cavity pump
and check the seals
Switch off the progressive cavity pump
and check the clamp connections
Grease the shaft surface on the sliding
ring seat with suitable lubricant
Replace the pump shaft
Replace the rotor and/or stator
Check the compatibility between rotor
and stator
Reduce the counterpressure
Switch off the progressive cavity pump
and remove the blockage
Replace the pump shaft
Have the direction of motor rotation
reversed by a qualified electrician
Let the motor cool down
Have the mains cable and plug
checked by a qualified electrician
Switch off the progressive cavity pump,
check the fluid level
Replace the pump shaft
Position the stator in such a way that
the lug of the stator housing engages
in the groove of the stator
