Fault description

Cause

Remedy

Personnel

Pumped volume
below the nominal
value

Suction height too large
(> 8 m / 26.25 ft)*

— Reduce the suction height

(lower the pump)*

Mechanics

Diameter of the suction
line (side of inlet) too
large or too small*

— Adjust the pipe diameter to the

pump output of the rotary lobe
pump*

Mechanics

Diameter of the pres-
sure line (side of outlet)
too small

— Adjust the pipe diameter to the

pump output of the rotary lobe
pump*

Mechanics

Shut-off devices not
open or not open com-
pletely, or pipes blocked

— Open shut-off device
— Clean the pipes

Mechanics

Counter-pressure too
high for other reasons

— Reduce the counter-pressure
— Install pressure monitoring

equipment

Mechanics

Speed too low*

— Increase the speed*

Mechanics

Viscosity of pumped
medium too high*

— Reduce the viscosity when pos-

sible*

— Change the pump position* or

install an auger upstream

Mechanics

Rotors damaged due to
dry run

— Replace the rotors
— Replace mechanical seal

(strongly recommended if rotors
were damaged due to dry run)

— Determine the cause of dry run

and eliminate it

Mechanics

Rotors damaged due to
foreign bodies

— Replace the rotors
— Install a macerator (Multi-

crusher, Multichopper) and a
stone trap upstream, if neces-
sary

Mechanics

Rotors worn as part of
regular use

— Replace the rotors

Mechanics

Wear on casing liners or
pump casing

— Replace worn parts
