A cylindrical piston pump with an inlet suction line and outlet discharge port. The pump is capable of lifting chlorine-containing fluid from out a portable container and, with little inducement save gravity, automatically transferring the liquid to a desired, generally lower location. The automatic transfer is effected by flap or analogous valve control; while semi-automatic is effected by rotary or shuttle, manually actuated valves. Outflow is enhanced by gravity, spring return of the piston and/or connection of the discharge line to a fluid entrainment assembly.

A fluid pump system for translating liquid in measured quantity from a lower reservoir to a liquid entrainment assembly comprising in combination: a cylinder member having a vented top cIosure and a bottom-disposed singular valve mechanism that is wholly contained in said cylinder, said valve mechanism including an inlet means for communicating with the cylinder member outlet means, a lower reservoir suction line and a discharge line, said valve mechanism configured to pass liquid up from the reservoir into the cylinder member and to allow said liquid to drain therefrom; a piston member slidingly disposed in the cylinder member for reciprocative movement between said top closure and the bottom valve mechanism, said piston member depending from a shaft that slidingly passes through said top closure; and, a coil spring disposed about said shaft between said piston member and said top closure, said discharge line disposed so as to feed said liquid to a location that is below said reservoir to connect with and join a filtered liquid flow by means of an entrainment device.
