DOWNERS GROVE, Ill., Sept. 9, 2026 /PRNewswire/ -- Blackmer, part of PSG, a Dover (NYSE:DOV) company, and a global leader in rotating pumps and reciprocating compressor technologies, today announced the launch of a behind-the-rotor seal for its Blackmer^® G Series Internal Gear Pumps. The new seal design delivers improved protection and performance when handling abrasive materials, helping extend the life of the pump across a range of applications.

Engineered for serviceability and longevity, the behind-the-rotor seal prevents process fluids and abrasive materials from contacting drive components of the G Series, resulting in reduced wear, simplified maintenance and increased uptime for operators.

"The introduction of the behind-the-rotor seal reflects our ongoing commitment to providing reliable pump technology and enhances the trusted performance of the G Series," said Joe Parzych, Product Manager of Blackmer. "By protecting critical internal components, this new seal helps customers minimize downtime and reduce total cost of ownership."

The behind-the-rotor seal includes the following key features:

Available in Type 1 or Type 8 seal configurations for greater flexibility.
Supports the use of a lower-cost bronze bushing when pumping abrasive materials.
Ideal for industries handling starches, inks, pulp, resins and adhesives.
Offered on G3-2 through G3-69 cast iron models, with additional materials planned for future release.
