Rotary vane pump with continuous fiber reinforced polymeric composite vanes less prone to catastrophic failure

A rotary paddle pump with sliding vanes and stationary side plates fabricated from a continuous carbon-fiber reinforced polymeric material, particularly polyetheretherketone (PEEK), polyetherketoneketone (PEKK), or polyphenylene sulphides (PPS) 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 continuous carbon-fiber reinforced polymeric composite may be alternately substituted to provide self-lubrication and low wear on surfaces moving relative to each other.
