A hand lift pressure pump presenting all components molded from ABS resin, PVC or other thermoplastic material so that the pump can be readily incorporated into any given installation utilizing thermoplastic conduits, fittings, adaptors and the like. In other words, the invention simplifies installation and overcomes basic difficulties in prior pumps fabricated from cast iron. The pump at hand is adapted to various end installations, including, by way of example, in connection with a driven well, a pressure system, for elevated storage and, additionally, a remote liquid or water supply, i.e. to eliminate water carrying.
