5.5 HP - 14 HP Gas Engine, Cast Iron Pump Units

2" & 3", Vac-U-Seal

When it comes to high volume, low pressure pumping of liquid fertilizers, agchemicals, liquid deicing, water, etc., this series of John Blue Vac-U-Double 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, along with a double "wet" seal, 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-Double Seal 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.
Cast iron heavy wall section provides extended life to unit.
Total Dependability and Versatility.
Designed for Many Chemicals and Fertilizers.
Speeds to 3600 RPM.
2 Year Unconditional Warranty (Centrifugal Pumps Only).
Long Coupled Units Include "Orange Peel" OSHA Approved Guard.
