Abstract:
1. A fluid handling pump adapted to be configured as a diaphragm pump, the fluid handling pump comprising: (a) a pump body comprising first and second bilaterally symmetrical halves joined together to form an enclosed cavity, each half including a tubular pipe member having first and second ends, one of said first and second ends on the tubular pipe member of the first half being a low pressure fluid inlet port and one of said first and second ends on the tubular pipe member of the second half being a high pressure fluid outlet port, said enclosed cavity defining first and second transversely extending pockets, each in fluid communication with lumens of the tubular pipe members and a longitudinally extending pocket intersecting with the first and second transversely extending pockets; (b) first and second reciprocally slidable connecting rod members disposed in the longitudinally extending pocket and having one of a plunger and a diaphragm at an outer end thereof, (c) first and second valve assemblies fitted individually into the first and second transversely extending pockets, each of the first and second valve assemblies comprising a tubular valve casing supporting an inlet poppet valve and an outlet poppet valve in spaced apart relation in opposed ends of the tubular casing, the tubular casing of each of the first and second valve assemblies each including a central opening generally aligned with the diaphragm employed; and d) an eccentric operatively coupled to the first and second reciprocally slidable connecting rod members.
