Abstract
A rotary paddle pump with sliding vanes and stationary side plates fabricated from a continuous carbon-fiber reinforced polyetheretherketone (PEEK) material yields characteristics of self-lubrication for dry operation, low wear for long life, and high flexural and tensile strength for superior resistance to foreign object damage. Other parts manufactured from PEEK may be alternately substituted to provide self-lubrication and low wear on surfaces moving relative to each other.
