When surface water is used for irrigation, the surface water contains a lot of sediment, organic debris and other poor water quality. The post-filter is prone to blockage and damage, which is difficult to find and clean. For this reason, a pre-pump filter device has been developed to reduce the sediment and impurities sucked into the pump.
