Blackmer, a leader in rotating pumps and reciprocating compressor technologies, recently launched a behind-the-rotor seal option for its G Series Internal Gear Pumps designed to deliver improved protection and performance when handling abrasive materials across a wide range of applications. 

Engineered for serviceability and longevity, the behind-the-rotor seal option is intended to prevent 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 company reported.

“The introduction of the behind-the-rotor seal underscores our ongoing commitment to providing reliable pump technology and enhances the trusted performance of the G Series,” Joe Parzych, Blackmer Gear product manager, said in a news release. “By protecting critical internal components, this new seal option 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
• Initially available on G3-2 through G3-69 cast iron models, with additional materials planned for future release

“By adding the behind-the-rotor seal option, operators can further expand on the versatility and dependability of their G Series Pumps,” Parzych concluded. “It’s a simple, high-impact solution for customers who want to maximize both the performance and longevity of their internal gear pumps.”
