About this product

Liquid-lubricated dual mechanical seals require an external source of fluid. A properly selected circulation system eliminates the need to connect to a distant and sometimes unreliable pressure source and creates barrier fluid flow when the seal cannot induce flow. Flowserve offers a complete line of standard circulators for a wide range of sealing applications and custom designed circulation systems based on your specifications.
