e mostsevere duties in mineral processing. The suction wearplateis subjected to rapid wear due to high solids concentrationand the coarse nature of the slurry. Goulds developeda proprietary process to locate and mold ceramic rods intothe rubber liner for the optimum combination of hardnessand resilience for extended wear life. Field trials confirmedCRM liner life of two to four times that of natural rubberalone. Because the CRM liner retains its shape longer, italso extends the life of the other wear parts for an evenlower life cycle cost.Bearing Cartridge AssemblyShaft Sleeve Hard Ni-Cr-coated XH-800 alloy sleeve 64 Rockwell C coating will not chip or crack Ground 6-8 RMS surface finish 316 SS base alloy for corrosion resistance Special alloys availableOptional Natural Rubber CRMWearplate for 10 10–28 SRL-XTXH-800 Shaft SleevesGoulds SRL3

Goulds SRLRubberFRP and Rubber Composite Hybrid LinersThe Goulds Model SRL utilizes a soft natural rubber blendthat offers the best combination of resilience and tearresistance for maximum wear life in abrasive and corrosiveslurries. Goulds offers a wide variety of natural andsynthetic rubbers as well as polymers in a range ofhardnesses to suit almost any slurry application.All SRL model liners are molded to a metal skeletonand bolted to the casing for a secure fit. However,on larger pumps, the amount of unsupported rubber inthe volute and discharge neck area can make them proneto collapse under adverse operating conditions. It also canbe difficult to handle and install. Goulds molds a fiberglass(FRP) shell to the casing liners for added support on pumpsizes 12 10–25 SRL-C and larger. This unique hybrid linerdesign is collapse-resistant with improved fit for easyhandling and assembly.FRP and Rubber Composite Hybrid LinersElastomer Selections and Application Guide for SRL PumpsPlease use the following chart as a general guide only.
