ABSTRACT:
A high-pressure water pump of the reciprocating piston type has its metal ston reciprocatable in a cylinder bushing composed of PEEK base high-strength thermoplastic synthetic resin and constructed so as to define a cooling clearance between the piston and the cylinder designed to prevent the temperature of the bushing on continuous operation from rising above 100.degree. C. The piston shoe and the slide bearing for the eccentric shaft should also be a PEEK based resin which can have a filler of carbon fibers, PTFE, glass fibers and/or mineral.
