Description

John Blue 3” Self-Priming Cast-Iron Centrifugal Pump Features
  • Patented Vac-U-Seal impeller design creates a vacuum between the impeller and mechanical seal. Lack of pressure on the seal face minimizes seal wear and results in a longer seal life.
  • Double wet seal design provides for continuous lubrication of the seal faces. This allows the pump to be run dry for extended periods without damaging the mechanical seal faces.
  • Closed impeller design minimizes thrust loading on the drive motor, extending the life of the drive motor.
