ABSTRACT:
A suction stabilizer for reciprocating pumps and method of stabilizing the inflow of liquid to the suction side of the pump. The stabilizer comprises a substantially cylindrical tank, a perforate-walled cage at one end of the tank, and a flexible resilient gas-filled bladder within the cage. Liquid passes through the tank as it moves from a source to the suction side of the pump. Between suction strokes the liquid compresses gas in the bladder. During suction strokes the pressure of the gas adds to the head of liquid entering the pump. The invention involves critical ratios of the tank volume to both the pump displacement and the bladder volume.
