Cast Iron Centrifugal Pumps Only, Self Priming "Vac-U-Seal"

Double Viton® Wet Seal

The Original Wet Seal Pump The Centrifugal Pump that is designed to Outlast Your Equipment!

When it comes to high volume, low pressure pumping of liquid fertilizers, this series of John Blue Vac-U-Seal Centrifugal pumps is considered the leader. The patented Vac-U-Seal system is derived from an inner function of the pump. The impeller applies vacuum pressure or suction to the seal which keeps harmful corrosive liquids and abrasive particles from entering the seal. This unique method of lubrication provides extended life for the seal, eliminates thrust loads increasing bearing life, and allows the pump to be operated dry without damaging the unit.

  • Patented Vac-U-Seal impeller design eliminates pressure on the seal resulting in long seal life.
  • Closed type hydraulically balanced impeller eliminates thrust loads for increased bearing life. Wear actually improves impeller efficiency.
  • No adjustments of impeller necessary with shims.
  • Pump can be operated DRY without damaging the seal.
  • Heavy wall section provides extended life to unit.
  • Total Dependability and Versatility.
  • Designed for Today's Chemicals and Fertilizers.
  • 3500 RPM
  • 2 Year Unconditional Warranty on Pump.
