How Rotorflush Self-Cleaning Filters Work

How Rotorflush Self-Cleaning Filters Work to keep Filter Mesh Clear in Dirty Water

It is no mystery how Rotorflush self-cleaning filters work. The same self-cleaning mechanism keeps the filter mesh clear on all our products. Our submersible filter pumps with their built-in self-cleaning intakes produce a continuous backwash to the filter mesh whenever they run. Our self-cleaning filters take a backwash flow from the filtered output of your surface mounted pump to keep their mesh clear. Here’s how:

Self-cleaning Filters and Strainers

Our self-cleaning filters and strainers, whatever their size, all work on the same basic principles – from the smallest pond and analyser filters up to the largest 1000 cubic metres per hour filters.  Rotorflush filters do not rely on a separate power source or motor to drive their effective self-cleaning mechanism.

They are driven water power from your pump – that’s how Rotorflush self-cleaning filters work.

These filters are designed for the suction side of surface mounted pumps; thus, as long as the pump is running Rotorflush self-cleaning filters will keep their filter mesh clear.

The pump draws water through the filter mesh. The filtered water is and pumped out from the pump for your use. The self-cleaning filter is back washed by taking a tee off the clean water output of your pump.  Our unique and patented self-cleaning filter mechanism is driven by a proportion of filtered water sent back to the filter.

The jets inside the filter gently remove debris, suspended solids and aquatic life away from the filter mesh without impeding the flow of water through the filter. Simple!


Please Note: Our filters are designed for use in dirty water or liquids with a viscosity close to that of water. Our filters and filterpumps are NOT suitable for use in raw sewage or any other dirty water which contains oils or fat.
