Cartridge Mechanical Seals

Mechanical Seals for any application

We offer a range of standard inventory cartridge mechanical seals, including single and double seals to suit even the most demanding application and thanks to our modular design system we offer them with the best on-time delivery performance in the industry.

For unusual applications our Standard Plus seal range offers all the benefits of a standard seal while meeting our customer’s specific needs. This covers competitor replacement seals, seals designed for specific pumps and seals designed for pumping specific processes. 

Proven Design - Cartridge Construction

Cartridge mechanical seal construction is a proven reliability improvement. The seals are pre-assembled at the factory, pressure tested and shipped as a unit, leading to improved performance as errors due to incorrect installation are reduced. Cartridge construction eliminates the need to measure and set spring compression, and having a mechanical seal pre-assembled means that the seal faces are protected from damage during installation.
