The machine does not start
Cause
Interruption of the power supply, short circuit/short-circuit to earth in
the conduit and/or motor winding
Trip fuses, circuit breakers and/or monitoring devices
The machinery starts, the circuit breaker is released, but is off shortly after start-up
Cause
The thermal trigger on the circuit breaker is set incorrectly
Impeller/propeller slowed down due to adhesions, obstructions and/or
solids, increased power input
The medium is too thick
The machinery runs, but does not convey
Cause
There is no pumped medium
Inlet obstructed
Impeller/propeller blocked/slowed down
Defective tube/pipe
Pump adhere on flexible ground
The machinery is running, the indicated operating values are not met
Cause
Inlet obstructed
Gate valve in the pressure pipe closed
Impeller/propeller blocked/slowed down
Air in the system
The machinery conveys against too high pressure
Wear and tear
Defective tube/pipe
Inadmissible content of gas in the pumped medium
Dual phase operation
Too strong drawdown in operation mode
The machinery does not run smoothly and makes noises
Cause
The machinery runs in inadmissible operating range
Pump inlet, intake strainer and/or wheel/propeller congested
Impeller does not run smoothly
Dual phase operation
Wear and tear
Engine mount defective
