ABSTRACT:
By pumping a liquid with a submerged rotary pump the distance from the submerged pump to the top of the riser pipe can be substantial and the liquid column left in the riser pipe from the pump constitutes a not insignificant residue. When the liquid level in the tank has sunk to the pump, the liquid in the riser pipe is caused to pass down into the pump and into and up through a relatively narrow pipe which leads from the pump housing at the pressure side of the pump impeller, the rotary impeller acting as check valve for the liquid.
