Rubber
The Goulds Model SRL utilizes a soft natural rubber blend that offers the best combination of resilience and tear resistance for maximum wear life in abrasive and corrosive slurries. Goulds offers a wide variety of natural and synthetic rubbers as well as polymers in a range of hardnesses to suit almost any slurry application.
FRP and Rubber Composite Hybrid Liners All SRL
model liners are molded to a metal skeleton and bolted to the casing for a secure fit. However, on larger pumps, the amount of unsupported rubber in the volute and discharge neck area can make them prone to collapse under adverse operating conditions. It also can be difficult to handle and install. Goulds molds a fiberglass (FRP) shell to the casing liners for added support on pump sizes 12×10–25 SRL-C and larger.
