In most filtration systems, be it membrane or sand filter, there is usually a backwash function. How it works is that the flow of water is reversed in order to flush out any sediments trapped in the filter.
A backwash pump is required to inject sufficient water into the filter at a certain pressure to remove the sediments trapped in the filter.
We carry a range of pumps that can be used to backwash filtration systems. Please contact our pump experts today for a free consultation.
