Harsha Filters

Devanahalli, Bangalore, Karnataka

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 facilitiessteel millsmining operationscement manufacturingpetrochemicals 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. technical specifications:material of construction:housing: low copper aluminium, mild steel, cast iron, stainless steel, - other materials and coatings available on request. flame element: ss316l, ss316, ss304, ss duplex, aluminium, brass, copper. end connection:flanged (as per requested table.), threaded (npt or bsp), tri clover adaptors, sms / dairy end connectionsizes:sizes are available from 1" line size to 24" line size.

We are one of the finest basket strainer manufacturers in india. Basket filters & strainers will permit the straining & filtering of a wide variety of fluids, to retain solids of almost any size. All baskets are easily removable & cleanable. Basket strainer elements can be offered in single, double or multi cylinder & pleated design depending upon requirement of application. They are constructed of filter housing, filter element supported with perforated cage, positive sealing arrangement to avoid any bypass & choice of end connections. Applications:power plantoil & gasprocess industriespetrochemicalssteelcementrefineriesfertilizerschemicalstextileslubrication systemswater treatment plant simplex strainer: simplex strainers are installed into systems that can be shut down for basket cleaning or change out. Technical specifications:material of construction:housing: low copper aluminium, mild steel, cast iron, stainless steel, - other materials and coatings available on request. flame element: ss316l, ss316, ss304, ss duplex, aluminium, brass, copper. element design:single cylinder design, double cylinder design, multi cylinder design, and pleated element designend connection:flanged (as per requested table.), threaded (npt or bsp), tri clover adaptors, sms / dairy end connectionsizes:sizes are available from 1" line size to 24" line size. Other/higher sizes available on request. Flow rate:capacity: up to 2000 m/ hr. More flow rates available on requestfiltration rating:filtration rating available from 5 microns to 2000 micronspressure rating:standard 5- 15 bar. High-pressure ratings available on request. duplex & multi strainers: a duplex or multi basket strainer can operate continuously and never has to be shut down for cleaning. This type of basket strainer has two separate strainer basket chambers, not just one like a simplex strainer. These chambers are put into service independently. When one basket chamber becomes full, the flow is switched to the other one. The strainer basket is then removed from the out-of-service chamber, cleaned and replaced, ready for use again.

We are offering duplex strainer, the duplex filter consist of two filters connected in parallel through a changeover device which consists of two balls housed in one housing, for operation with a single handle. We are authorized duplex strainers manufacturer and duplex basket strainers manufacturer. inlet and the outlet at the same level and in opposite direction. Therefore the filter as such can be installed in existing pipeline. side bodies (filter housings) are flange mounted with our unique double ball changeover device and can be made to any size to increase filtration area and debris collection volume. leak proof design with bubble tight sealing as in the case of ball valves. easily replaceable ptfe seats of balls. type :duplex strainers / filters. application:filtration of liquids , gas, water, lube & fuel oil , chemicals etc. construction:close grain cast iron , bronze, cast steel, stainless steel andfabricated construction . connections:flanged , screwed , s.w ends flanges in din, asa or to customer's specifications. range:a) pressure : 150#, 300# and above.

We are one of the finest y/t strainers manufacturers in india. y/t strainers take their name from their configuration. They are most commonly used in pressurized lines, gas or liquid, but can also be used in suction or vacuum conditions. They are intended for applications where small amounts of solid particulate are expected, and where clean-out will be infrequent. If solids will flush easily from the screen, and fluid can be exhausted to atmosphere, a blow-down valve on the drain port will allow clean-out without removal of the screen, and without interrupting the process flow. Applications:pump protection, flow meter protection, valve and regulator protection, protection of heat exchanger and refrigerating set, protection of steam traps, instrumentation and ancillary piping item protection etc. technical specifications:material of construction:housing: carbon steel, stainless steel in various grades, - other materials and coatings available on request. filter element: carbon steel, stainless steel in various grades - other materials available on request. end connection:flanged (as per requested table.), threaded (npt or bsp)sizes:sizes are available from 1/2" line size to 24" line size.
