Self-cleaning Filters for Dirty Water
We offer two main product sets incorporating our unique and patented self-cleaning filtration system:
Submersible filterpumps with integral self-cleaning intake filters
Self-cleaning suction filters and strainers for use with dry mounted pumps
All our self-cleaning filters have low velocity intake and the constant backwash keeps the filter screen clear of debris without interrupting the flow.
Why you need a Rotorflush Filter
Our filters keep irrigation equipment going, water works working, fountains flowing and protect pumps, heat exchangers and analytical instruments.
The first type of product is a submersible filterpump with integral self-cleaning intake filter.
Our filterpumps are submersible, continuously rated and have their own built -in self-cleaning filter. The filter mechanism on the pump is driven by an additional impeller on the pump motor shaft and the cleaning jets keep the filter mesh clear of any suspended solids, debris, etc to protect the pump and other equipment.
Because of the large open area of our intakes and the low velocity intake these filterpumps – when fitted with 2mm mesh – comply with Eel Regulations. It is not possible to retrofit these filters to an existing submersible pump. We have selected a variety of pump makes for our product ranges but we then redesign the drive shafts, pump ends and add additional impellers to produce a submersible pump with a self-cleaning suction intake.
We offer submersible pumps from 150 litres a minute up to 1800 litres aminute, and mesh sizes from 60 microns (on smaller submersibles) to 6mm.
They enable greater water efficiency through recycling and re-use, reduce downtime spent on pump and filter maintenance, reduce energy bills and lower dirty water disposal costs.
The second type of filtration product we offer are self-cleaning filters for use with surface mounted pumps. These stainless steel filters are extremely tough and require little maintenance.
Our filters are driven by taking a tee off the filtered output of your pump and sending a flow of filtered output back to the filter to drive the backwash mechanism inside. The cleaning effect is the same as the submersible pump filters. These filters have no power source other than your pump when it is in operation. Have a look at the ‘How it works’ document attached.
We offer self-cleaning filters from 30 litres a minute up to over 1000 m3 / hour, and mesh sizes from 60 microns (on smaller filters) to 6mm.
We can also design and build self-cleaning intake strainers to suit your particular requirements
Our customers benefit from our knowledge gained from years of successfully producing self-cleaning intake filters in shapes, sizes and designs that meet their particular filtration needs.

How Rotorflush Works
Check out this video all about how Rotorflush filters work
Filtering directly from your water source can save capital costs where sites need to be built for other filtration solutions.
Our self-cleaning intake filters provide an excellent return on investment, by reducing downtime and maintenance and protecting equipment from blockages.
Our self-cleaning filters are Eel friendly.
The design of our filters gives them a low intake velocity and a high open area, enabling compliance with current Eel regulations when pumping and abstracting raw water.MORE ABOUT EEL REGS
