Test Run With Medium - Borger Classic FL Series Operating Manual

5.1.1

Test run with medium

90
NOTE!
Rotary lobe pumps are self-priming positive displacement
pumps.
However, we recommend filling the pump with medium for suction
operation before switching it on. This shortens the priming
process and prevents dry run with increased wear.
— Suitable equipment for filling and venting may be required in
the suction and pressure lines.
— The pump should be prepared so that venting is possible
directly behind the pump, on the pressure side, during the
initial priming process.
— If the suction line is flooded with medium (e.g. gravity
feed), only the pipes need to be free and all valves open to
ensure the unrestricted transportation of pumped medium
and any air remaining in the pipe.
