  PRW has continued the evolutionary process on your existing line of water pumps. Performance Quotient Engineered pumps will flow 35 Gallons per minute at 4,000 RPM with minimal cavitation and proportionally increased flow rates at 5,000 RPM and above.

   

  Equalized water flow distribution and pressure-balanced water passages minimize internal engine hot-spots, making these pumps an excellent alternative for not only racers but also trucks, towing, and motorhome applications. Cruisers and hotrodders will appreciate the improved cooling at low speeds and the polished aluminum water pump bodies. 

   

  Designed for serious competition, racers and engine builders can look forward to

• • Steel hubs and heavy duty shielded-seal roller ball bearings
  • Pressure injected and cast aluminum allow pump bodies
  • Back plate “O” ring sealed for racing applications
  • Reliable cast iron CNC machined impellers
  • Satin-cast or polished finish housings
  • Aircraft industry tolerances
