Abstract: A pump includes a liquid housing having a liquid chamber with a piston/diaphragm assembly arranged therein that responds to a suction stroke and draws liquid into the liquid chamber, and responds to a pressure stroke and provides liquid from the liquid chamber; and a gas housing having a slide valve assembly separating first and second gas chambers. The slide valve assembly responds to a suction-to-pressure-force at the suction stroke conclusion, changes from a suction-to-pressure stroke state, provides gas from the first to second gas chamber through the slide valve assembly, and provides the pressure stroke so liquid passes from the liquid chamber; and responds to a pressure-to-suction-force at the pressure stroke conclusion, changes from the pressure-to-suction stroke state, provides gas from the second chamber through the slide valve assembly, and provides the suction stroke so liquid is drawn into the liquid chamber.

Abstract: A pump includes a molded housing configured with a rear endbell portion to receive an armature and bearing, an intermediate motor portion to receive a motor shell and magnets arranged around the armature, and a front endbell portion to receive a diaphragm assembly having a diaphragm support plate supporting a diaphragm, the rear endbell portion, the intermediate motor portion and the front endbell portion being configured as an integrated molded housing unit, the diaphragm having two circumferential diaphragm sealing surfaces. The pump also includes an upper housing configured to assemble and couple to the molded housing so as to form a circumferential fluid-tight sealing arrangement that is configured between the front endbell portion and the upper housing on only one end of the pump.
