ABSTRACT:
Apparatus as disclosed for eliminating drawdown of the level of liquid in a sump suction type of pump having a cover gas above the liquid therein. The liquid level is maintained throughout all pump operating speeds and without the need to vary the cover gas pressure of the pump. The pump includes a divider plate which separates the sump tank into upper and lower chambers. When the speed of the pump increases, the divider plate serves to limit the amount of liquid flowing therepast. An orifice flow tube connects the pump outlet to the upper chamber of the sump tank. Thus, the leakage flow past the divider plate is pumped back into the upper chamber thereby automatically compensating for the effect of pump drawdown.
