Regenerative turbine pumps "vapor lock" when reaching their maximum differential
pressure capability. High differential pressure can be due to restrictions in
discharge piping/hose. Improperly installed piping can also cause vapor locking.
See installation guidelines.
Valve closed in inlet or discharge line.
Open the valve.
Excess
flow valve slugged or closed
Stop pump until valve opens. If problem continues, install new or larger capacity
excess flow valve.
Wrong rotation
Check the rotation of the electric motor, and change the rotation.
Suction pipe too small or restricted
Indicated by pump's inlet pressure dropping when the pump is started. Remove restrictions
and/or increase pipe size.
