Automatic Self-cleaning Water Strainers are strainers on the inlet side of a pump. They screen out debris and that might block the pump and have an automatic means of keeping the strainer mesh clean.

Rotorflush automatic self-cleaning water strainers are an excellent example. They are coarse screened self-cleaning strainers that connect to the suction hose of surface mounted pumps. These automatic strainers are fitted with a single sheet of perforated stainless steel mesh which forms the filter cage. Standard perforated mesh sizes are 3mm and 6mm. The automatic self-cleaning strainers have a capacity range of 220 litres per minute to over 1000 m3 / hr.

All our self-cleaning water filters and strainers have an internal cleaning rotor that is powered by water taken via a 'T' off the output of your pump. This water supply continuously backwashes the automatic strainer screen by pushing away anything that might cause it to block or blind.

These automatic self-cleaning water strainers can operate in very dirty water and are ideal for use where there is a need to filter coarsely to protect pumps and other downstream equipment.
