3.4Pump Priming
IMPORTANT: THE INLET PIPING AND PUMP MUST BE FILLED WITH LIQUID (i.e.,
PRIMED) BEFORE START-UP.
If the pump is above the liquid source, fill the pump and supply line with liquid from an external source.
WARNING: THE PUMP MUST BE SHUTOFF IMMEDIATELY IF PRIME IS LOST TO AVOID POSSIBLE DAMAGE TO THE INTERNALS OF THE LIQUID END.
WARNING: NEVER RUN PUMP DRY.
The liquid end of your Tonkaflo pump is lubricated by the process fluid. The pump must never be run dry to avoid damage to the liquid end.
3.5Protection Against Running Dry
It is suggested that controls to protect the pump from running dry be used. These controls include: pressure switches, flow switches, and temperature switches.
