The wedge wire principle is utilised in a wide variety of industrial applications and has proved highly successful in the brewing and beverage industry for fruit pith and particle removal.  Wedge wire screens have also been used with some considerable success in smoothing high value products such as Shampoo and Creams in the cosmetic industry and Yoghurt and Soft Cheeses in the dairy industry. 


Alchem offer a range of Screenflow strainers in 3”, 4” and 6” housings.  These housings offer a variety of flow capacities and attachment options to suit a range of process requirements.


High flow-rates and pressures are achievable with the wedge-wire screens and the robust construction of the cylindrical wedge-wire elements allows for high working pressures. 


Back flushing is possible at up to 75% of the maximum working pressure.
