A duplex basket filter is an industrial filtration device designed for continuous operation without shutdown. It consists of two basket filter chambers arranged side by side and connected through a changeover valve or lever mechanism.
Working Principle:
- While one basket filter is in service, the other remains on standby.
- When the operating basket becomes clogged, flow is smoothly diverted to the standby basket.
- The clogged basket can then be cleaned or replaced without interrupting the process.
Key Features:
- Continuous filtration with no process downtime
- Quick and easy changeover mechanism
- High dirt-holding capacity
- Robust construction (commonly cast iron, carbon steel, or stainless steel)
- Removable perforated or wire-mesh baskets
Applications:
- Oil & gas pipelines
- Chemical and petrochemical plants
- Water treatment systems
- Power plants
- Pump and compressor protection
Purpose: Duplex basket filters are used to remove solid contaminants from liquids or gases, protecting downstream equipment such as pumps, valves, meters, and heat exchangers.
