Industrial Grade Excellence
Stainless Steel Basket Strainer Manufacturer, Industrial SS Basket Filter & Duplex Strainer Supplier in India
VVIOK Industry is an established, high-precision basket strainer manufacturer and engineering enterprise based in Ahmedabad, India. Designed for heavy-duty pipeline protection, our simplex and multi-basket systems prevent catastrophic damage to expensive downstream pumps, valves, heat exchangers, flow meters, and spray nozzles by intercepting pipeline scale, particulate debris, and suspended solids. As an ISO 9001:2015 certified basket strainer supplier, we design robust filtration assemblies engineered in full compliance with ASME Section VIII Division 1 and ASME B16.34 standards, delivering reliable fluid clarification across chemical processing, oil & gas, pharmaceuticals, marine, and power generation sectors.
Recognized among premier basket filter manufacturers, we build each filtration vessel and internal assembly using certified materials, including carbon steel, AISI 304, AISI 316, and AISI 316L stainless steel, as well as Duplex and Hastelloy for highly corrosive or saline fluids. At the heart of each unit is a heavy-duty stainless steel strainer basket industrial grade screen, constructed with a thick perforated metal backing plate lined with high-precision wire mesh down to 20 microns. Whether you require a standard ss basket strainer for water utility lines or an electro-polished stainless steel basket strainer for sanitary pharmaceutical operations, our baskets feature top lifting handles, machined sealing rings, and heavy-gauge handles for rapid, tool-free maintenance.
To ensure continuous, zero-downtime operation in critical process lines, VVIOK Industry is an industry-leading duplex basket strainer manufacturer. Our duplex configurations incorporate dual filtration chambers interconnected via an integrated 3-way or 4-way diverter ball valve or equalizing butterfly valves. When one chamber fills with particulate, operators can switch fluid flow to the parallel chamber without pausing production, allowing safe basket servicing. This continuous-flow capability makes our assemblies the preferred choice for continuous cooling towers, boiler feed lines, fuel oil handling, and petrochemical transfer loops.
As a specialized basket type strainer manufacturer, we provide standard ANSI 150#, 300#, and 600# flanged connections in sizes from 1 inch up to 48+ inches. Furthermore, every stainless steel basket filter is engineered with a generous open area ratio—providing 400% to 600% greater free straining area than the connecting pipe cross-section to minimize differential pressure drop (ΔP). Each strainer undergoes comprehensive hydrostatic pressure testing, radiographic weld inspection, and comes backed by EN 10204 3.1 Material Test Certificates (MTC) and quality dossiers.
