Abstract

A pump apparatus is provided which comprises a displacement pump and a check valve apparatus. The displacement pump comprises a reciprocating piston within a housing having an interior wall spaced apart from the piston. The check valve apparatus comprises two check valves that control fluid flow under pressure exerted by the reciprocating piston from a fluid reservoir to a point of use of the fluid.
