Problem
Cause
Effect
Corrective measure
The pump is unable to
create a vacuum
• Service liquid valve is
closed
• The pump is not
receiving enough
service liquid
• The temperature of the
service liquid is too
high
• Reduced output
• The pump can become
damaged during
cavitation
• Check service liquid
valve
• Check the liquid
supply
• Stop the pump
and wait until
the temperature
has dropped to
a sufficient level,
or lower the
temperature of the
service liquid inlet
The start-up power is
too high
• Too much service liquid
in the pump prior to
start-up
• Noise at start-up and
possible overload of
the power supply
• Check the stop valves
in the liquid supply
for leakage
Noise during operation
• Cavitation
• Too much water
in the pipe system
when switching from
pressure to vacuum
• Severe damage to the
pump and potential risk
of breakdown
• Adjust the service
liquid pressure
• Redesign the pipe
system (critical pipe)
Leakage from the
bearing housing’s drain
holes
• Damaged shaft seal
• Bearings may become
damaged
• Potential risk of
explosive gas leak
• Stop the pump
and contact the
manufacturer
