Blackmer has introduced a behind-the-rotor seal option for its G Series Internal Gear Pumps, aimed at improving reliability in abrasive fluid-handling applications.
The new option is designed to protect key drive components by helping prevent process fluids and abrasive materials from reaching internal areas that are more vulnerable to wear.
Blackmer, a brand of PSG, part of Dover Corporation, said the seal design is intended to support longer service life, simpler maintenance and increased uptime for operators using Blackmer G Series Internal Gear Pumps.
Designed for abrasive applications
Internal gear pumps are used across a range of industrial and process applications where fluids can vary in viscosity, temperature and abrasiveness. In applications involving materials such as starches, inks, pulp, resins and adhesives, protecting the seal area and drive components can be important for reducing wear and unplanned maintenance.
The behind-the-rotor seal option is available in Type 1 and Type 8 seal configurations, giving operators flexibility across different pumping requirements.
Blackmer said the design can also support the use of a lower-cost bronze bushing when pumping abrasive materials, depending on the application.
“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,” said Joe Parzych, Product Manager of Blackmer Gear.
“By protecting critical internal components, this new seal option helps customers minimise downtime and reduce total cost of ownership.”
Initial availability
The behind-the-rotor seal option is initially available on G3-2 through G3-69 cast iron models. Blackmer said additional materials are planned for future release.
The company positions the option as an extension of the G Series platform, which is used in fluid transfer applications across process, transport, energy, industrial and related markets.
“By adding the behind-the-rotor seal option, operators can further expand on the versatility and dependability of their G Series Pumps,” Parzych said.
“It’s a simple, high-impact solution for customers who want to maximise both the performance and longevity of their internal gear pumps.”
