Product Overview | Duplex Basket Strainers
Like other basket strainers, the duplex gas and oil strainers protect expensive downstream equipment by mechanically removing solids from flowing fluids via a perforated or mesh- lined perforated basket. However, the duplex strainer is designed with two basket chambers and a flow diverter system that allows the pipeline flow to be switched from one chamber to the other, completely isolating the flow to a single chamber. Thus, the duplex strainer is ideal for non-interruptable applications that can't be shut down for routine maintenance and cleaning operations. A common shaft engages two stainless steel balls that effectively divert the pipeline flow from one basket chamber to the other. Teflon seats ensure a positive seal and help to prevent seepage into the chamber being serviced.
A low-torque, manually-operated handle makes it easy to divert the flow stream for servicing. The handle position covers the strainer chamber in service and provides easy access for the chamber to be serviced. FKM O-rings and PTFE seat seals permit operation for ambient or heated oil applications. These seal materials are also suitable for natural gas usage. O-rings seals are supplied in complete kits.
CANADIAN REGISTRATION NUMBER (CRN)
When strainers require CRN, order the steel bodied versions. Cast iron strainers do not carry CRN.
