Abstract

626,274. Centrifugal pumps. DRYSDALE & CO., Ltd., and DRYSDALE, J. W. W. Aug. 22, 1947, No. 23292. Drawings to Specification. [Class 110(i)] A centrifugal pump for use alternatively as a fire pump and a bilge pump is primed, when used as a bilge pump, by a liquid ring pump. When used as a fire pump, the pressure of the delivery, applied to a spring-loaded piston, moves a multiported piston valve to a position in which it opens the suction side of the liquid ring pump to atmosphere and permits the escape of the sealing liquid.
