Self Cleaning Strainers - High-efficiency Back Flush Design | Automatic Filtration For High Suspended Solids And Viscous Materials

We are one of the finest Self Cleaning Strainers manufacturers in India. Back flush strainers have been specifically designed for use in applications where an automatic cleaning strainer is required to ensure process continuity. They are very useful for applications where suspended solid load is comparatively high. They are also useful for filtration of highly viscous material and slurry-based filtration applications. Their working principle is based on the differential pressure parameters across the filter. One can set a clean pressure drop and a change-out pressure drop for uninterrupted filtration.
OPERATION
Back wash type self cleaning filters work on a flow direction of outside to inside. Unfiltered fluid enters into filter housing through bottom tangential inlet connection. Contaminants are deposited on the outer surface of filter elements and clean filtrate passes through inside diameter of element and removed through the top tangential outlet. Users can set their differential pressure data within control panel. Once the differential pressure across the system reaches the pre-defined level of pressure drop, inlet and outlet valves shut down and the drain and backwash valves open for defined interval of time. During this process, debris deposited on outer surface of element shall be drained out and collected through bottom drain. This cycle continues as per pre-defined settings and process requirements.
