Filter Backwash Applications

Filter Backwash pumps are used to flush filters which become clogged by sand, seaweed, and other debris. Due to fluid constantly being drawn through the mesh, it can lead to some debris being caught, which may be larger than the gauze. Pumps are used to force fluid through the gauze clearing any debris. Clogged filters can be detected by a differential pressure gauge / switch, pumps cavitating and particles downstream from the unit which ordinarily would not be present. Regular backwash cycles, or self-cleaning filters prevent this from occurring.
