Self Cleaning Strainers

We are offering self cleaning strainers.
self cleaning strainers or 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.
applications:
 pulp and paper
 sewage treatment industry
 water and water treatment
 chemical plants
 food processing facilities
 steel mills
 mining operations
 cement manufacturing
 petrochemicals
how it works:
automatic self-cleaning strainers are commonly used on water service where the disposal of debris and backwash water is not a problem. Continuous flow is assured and protection is provided for nozzles, pumps, valves, heat exchangers and other process equipment. These high quality strainers can also successfully handle other fluids such as white water, black liquor, starch, fuel and lubricating oil, caustic solutions and cooking oils. A determining factor in these cases is the recycling of the backwash fluid. Automatic self-cleaning strainers will significantly reduce maintenance costs and provide uninterrupted flow. They are a particularly worthwhile investment where solids loading are high or upset conditions occur. Frequent cleaning and servicing of manual strainers is costly and, if not properly done, serious disruptions to the entire piping system can occur. Also, they are an ideal solution for maintenance problems where the strainer is in an inaccessible or remote location. Automatic strainers can easily replace duplex basket strainers.
back wash strainer:
backwash duplex filters are essentially duplex filters with difference. Sure, it is usual one working and other standby unit. But after change over upon one of unit choking, no need of opening of the unit for cleaning. The choked filter can be simply backwashed for cleaning and thus will be ready for next change over, all without opening. Backwashing strainer / filters are known for minimizing operator exposure and the backwash fluid is ideal for hazardous environment. These backwashing water filters are available in both manual as well as automatic mode. They are noted for reduced process downtime and maintenance cost with increased productivity.
