Description
Duplex Type Strainer Manufacturer & Exporter in India
FlowBiz Duplex Type Strainers (also known as Twin Basket Strainers) are engineered for continuous, uninterrupted fluid filtration in critical industrial pipelines where system shutdowns for filter cleaning are unacceptable. Built with two parallel filtration basket chambers connected via an integrated 3-way or 4-way diverter valve, these strainers allow operators to isolate and clean one clogged basket chamber while fluid flow continues through the alternate chamber at full capacity.
Key Performance Features & Diverter Mechanism
- Zero-Downtime Continuous Filtration: Integrated changeover diverter valve allows instantaneous inline diversion from a dirty basket chamber to a clean chamber without interrupting line pressure or flow rate.
- High Dirt-Holding Basket Capacity: Dual stainless steel mesh basket inserts offer large filtration surface areas to handle heavy particle loads, viscous oils, and slurry fluids with minimal pressure drop.
- Quick-Release Cover Design: Equipped with top-entry quick-opening covers and drain/bleed ports for safe, tool-free basket extraction and maintenance during active system operation.
- Equalization & Venting System: Built-in pressure equalization valves prevent pressure surges and liquid hammering when switching flow between chambers.
