We are one of the highly established designers, manufacturers and suppliers of Duplex Type Strainers,Duplex Basket Strainer and Duplex Filters Strainers. Which are used wherever continuous operation is required and flow is not interrupted for cleaning of filter element. It consists of two filtration chambers,each rated for 100% capacity connected in parallel by means of 3 way ball valve, Butterfly Valve, Gate Valve & NRV. Diversion of fluid flows without interruption of flow with manual change over valve or automatically operated. Its higher flow rates handled by disc type change over system possess large filtration area for raw water/sea water, etc.

It can be fabricated in casting/fabrication as per requirement and can also be available with steam jacketing for fluid like (L.D.O./H.F.O./Bitumen, etc.). We offer a wide range of Duplex Types Strainer filtration from 2 micron to 500 microns. Our Duplex Type Strainers are highly economic, handy and easily accessible in the market. We have highly experienced professionals, who are master of Strainers manufacturing industry.
