ANSI and DIN Products

The Westech Ben-O-Seal Cartridge and type 401 and 402 is a proven, reliable and cost effective seal design for most applications requiring an unbalanced seal design. Developed for demanding applications where a balanced seal is too much, this seal is well suited in ANSI or DIN pump applications.

Machined from premium materials, these cartridge seal designs are versatile, reliable, and user friendly in most ANSI applications and demanding services. We are so impressed with the value and reliability of these cartridges that we have included them as the seals of choice in our Pro-Kit Power Frame Upgrade Kits. But don't take our word for it, ask for references, or try one in your application.
