Industrial Grade Excellence
Industrial Strainer Filter Housing Manufacturer, SS Basket Strainer Filter Housing & SS Single Strainer Filter Housing Supplier in India
VVIOK Industry is a premier Industrial filter manufacturer headquartered in Ahmedabad, Gujarat, India, specializing in the precision engineering and custom fabrication of high-capacity SS Basket Strainer Filter housing systems. Designed to protect mission-critical pipeline equipment such as pumps, flow meters, heat exchangers, spray nozzles, valves, and analytical instrumentation from abrasive wear and catastrophic debris damage, our industrial strainer vessels deliver exceptional particle capture efficiency with minimal system pressure drop. Engineered from certified stainless steel (AISI 304, 304L, 316, 316L) and high-performance alloys, our strainer housings ensure 100% bypass-free operation under continuous, rigorous industrial environments.
To accommodate distinct flow dynamics, piping configurations, and maintenance schedules, we manufacture multiple Strainer filter housing types tailored to industry-specific demands. For batch processes, intermittent operations, or installations where brief line shutdowns are permissible during screen servicing, our SS Single Strainer Filter Housing (simplex basket strainer) offers an economical, space-saving, and highly dependable solution featuring an exceptionally high free open area ratio. For continuous 24/7 operating facilities where liquid flow cannot be interrupted, we engineer heavy-duty Duplex Strainer Filter Housings equipped with integrated three-way diverter valves or synchronous butterfly valve manifolds, permitting uninterrupted basket cleaning and changeout. Additionally, our engineered multi-basket vessels handle large intake volumes up to 3,500 m³/hr for municipal water, cooling towers, and power generation.
The core filtering element inside every strainer vessel is an engineered stainless steel basket. Selecting the optimal basket filter mesh size and strainer filter mesh size is fundamental to balancing particulate capture efficiency against differential pressure build-up. Our strainer vessels support an extensive range of filtration media—from heavy-duty perforated sheet metal cylinders (1 mm to 10 mm hole diameters) for coarse straining, to multi-layer woven stainless steel wire cloth and sintered metal composite linings. Whether your process requires coarse debris retention or an ultra-precise strainer micron size rating ranging from coarse 2,000 microns down to 5 microns, VVIOK Industry customizes basket geometry to deliver maximum dirt-holding capacity and prolonged operating cycles.
Every SS Basket Strainer Filter housing fabricated at our Ahmedabad manufacturing plant adheres strictly to ASME Section VIII Division 1 guidelines and international piping standards. Featuring ergonomic quick-opening swing-bolt covers with counterbalanced mechanical davit arm assemblies, tool-free basket changeout is accomplished safely within minutes. Equipped with zero-bypass elastomer seals (Viton, EPDM, PTFE, or Food-Grade Silicone), differential pressure gauge ports, bottom clean drain valves, and top air vent valves, our strainer filter housings serve chemical processing plants, oil refineries, pharmaceutical facilities, water treatment utilities, and food manufacturing plants globally with certified reliability.
