Abstract
A high efficiency pump having relatively-moving parts constituted of a light weight material and a coating on at least one of the parts to effect essentially zero clearance between the parts where they merge together. The coating is comprised of solid lubricants in a polymer resin matrix stable up to 700.degree. F.
Claims9
A high efficiency fluid pump for compressing gases or pumping liquids, comprising:
- a. means for effecting a pumping action by use of relatively movable parts which cyclically move together and move apart at a zone to transfer fluid, the said parts being constituted of a light weight material;
- and
- b. a coating on at least one of the parts to provide essentially zero clearance when said parts have moved together at said zone, said coating comprising solid lubricants in a polymer resin matrix having a temperature stability up to 700.degree. F.
