Duplex Strainer

Duplex Straner is a coarse filtration equipment with a dual chamber and dual filter basket structure in industrial pipelines. It can achieve non-stop cleaning/replacement of the filter screen by switching valves. Its core is used to intercept large particle impurities in the medium and protect downstream equipment.Widely used in industries such as petrochemicals, power, and water supply and drainage, it is suitable for critical pipeline systems that cannot be shut down for continuous operation. It filters impurities in water, oil, and gas, prevents equipment wear and blockage, and ensures the continuous and stable operation of the system.

Common Types

  • Stainless steel dual filter: made of 304/316L material, corrosion-resistant and easy to clean, suitable for clean/corrosive media
  • High pressure dual filter: pressure resistant design, suitable for high-pressure pipeline conditions, strong impact resistance

Structural Advantages & Corresponding Benefits

  1. Dual chamber dual filter basket+switching valve structure

  • Special point:  Dual chamber independent with filter basket, equipped with switching valve, can quickly switch working chambers
  • Result:The filter can be cleaned/replaced without stopping the machine, without interrupting production, and improving system operating efficiency

  1. Wear resistant seal+standardized interface structure

  • Special point: wear-resistant design of the filter basket, multiple seals at the shaft end, and interfaces that comply with universal standards
  • Result:  Leak proof, long service life, can be directly connected to existing pipelines, easy to install
