Duplex Basket Strainers / Pipeline Strainers
Duplex Basket Strainers are designed for applications where continuous flow must be maintained whilst cleaning filter baskets. The strainer uses integral 3 way stainless steel ball valves with PTFE seals. This design provides drop tight shutoff eliminating costly and potentially dangerous leakage into the chamber not in use which can occur in some other duplex strainer designs. This also eliminates some problems which can occur in particular suction conditions where in other designs air ingress could occur. All parts of the valve mechanism are accessible after removing the basket chamber without taking the strainer out of the pipeline.
The handle covers the strainer chamber when in use and prevents accidental opening of the filter cover.
- Available in cast iron, bronze, carbon and stainless steel.
- Pipeline sizes from 20mm (3/4”) to 200mm (8”) (ask for details of sizes above 200mm).
- Available flanged in all common drillings including PN16 and ANSI150 (ANSI300 and 600 on request) and screwed ports both BSP and NPT or socket weld.
- XD range up to 13.8 Barg (pressure stated at 50C, lower pressure at
higher temperatures, ask if unsure). Temperature limited by chosen seal.
Pressure also limited by flange rating.
- Large filter baskets areas, manufactured in st. steel 316.
- Various options including differential pressure indicator, magnets and
- Can be coated internally and externally.
