John Crane Launches New Sealing Solution That Extends Mean Time Between Repair and Reduces Water and Power Consumption

The Type SB2/SB2A USP seal combines heavy-duty dual
cartridge seals with unique upstream pumping technology

CHICAGO (April 19, 2023) ― John Crane, a global leader in rotating equipment solutions, supplying engineered technologies and services to process industries, today announced the launch of the Type SB2/SB2A USP seal—combining the Type SB2/SB2A heavy-duty dual cartridge seal with their unique Upstream Pumping (USP) technology.

John Crane’s new sealing solution enhances the company’s current USP product portfolio to include a more robust seal, improving service in the pulp and paper and mining industries, where the Type SB2/SB2A is recognized for its exceptional performance.

The Type SB2/SB2A USP seal is ideal for use with environmentally hazardous and abrasive fluids and other slurry duties up to 40% solids by weight and a solids hardness of eight Mohs. It is widely used on pumps and other rotary equipment.

“Adding our one-of-a-kind USP seal face technology to our Type SB2/SB2A seal is a game-changer,” said Terry Lemm, Portfolio Director, Universal Sealing Solutions. “Customers who regularly work with harsh and abrasive slurries will now have another tool for extending mean time between repair while nearly eliminating water consumption and reducing power consumption.”

This new product will offer the same benefits as the other seals in the USP product line, including:

  • Extended mean time between repair
  • Significant water reduction
  • Energy savings
  • Zero-emissions
  • Lower total cost of ownership

The Type SB2/SB2A USP seal pairs with the recently launched GS USP standardized support system. By providing a standardized support system, customers will benefit from reduced complexity, a small footprint and a lower total cost of ownership.

Two variants of the design are available for different equipment, including:

  • Type SB2-USP, designed for DIN standard dimensions
  • Type SB2A-USP, designed for ANSI standard dimensions
