Behind-the-Rotor Seal Protects Gear Pump Drive Components

Need to Know
- The seal is designed to prevent process fluids and abrasive materials from contacting drive components in G Series Internal Gear Pumps.
- It is available in Type 1 or Type 8 configurations and initially covers G3-2 through G3-69 cast iron models.
Blackmer has introduced a behind-the-rotor seal option for its G Series Internal Gear Pumps, designed to improve reliability and service life when handling abrasive materials.
The seal design prevents process fluids and abrasive materials from contacting the pumps’ drive components, which the company says can reduce wear, simplify maintenance and increase uptime. The option is available in Type 1 or Type 8 seal configurations and supports the use of a lower-cost bronze bushing when pumping abrasive materials.
Blackmer identifies applications involving starches, inks, pulp, resins and adhesives among the intended uses. The option is initially available for G3-2 through G3-69 cast iron models, with additional materials planned for future release.
