Self-Cleaning Suction Intake Filters & Strainers
Rotorflush Self-Cleaning Suction Intake Filters & Strainers are for use with surface mounted pumps. They are a welcome alternative to the traditional suction intake basket strainer. All our filters are self-cleaning automatic backwash filters – the self-cleaning mechanism prevents the filter blinding or the pump blocking.
Rotorflush filters fit to the suction hose of surface mounted pumps, They use the power of the water being pumped to continuously clean and clear the filter mesh. They provide an uninterrupted supply of filtered output protecting your equipment from blockage.
Self-Cleaning Suction Intake Filters & Strainers – Filter from 14 m3 to 275 m3 / hour
Our self-cleaning suction intake filters & strainers have capacities from 14 to 1000 cubic metres per hour. Screen apertures range from 60 microns to 10mm depending on models. They are used successfully and reliably within the water treatment industry and oil and gas sector. Our filters and screens deliver low maintenance efficient filtration in very difficult conditions.
The coarser ‘R’ series strainers and the finer ‘A’ series filters have an internal cleaning rotor that is powered by the pump output. By taking a ‘T’ off the output of the pump a small flow of water is directed back to the filter. This flow drives the Rotorflush internal self-cleaning rotors. The rotors continuously backwash the mesh screen removing anything that might cause it to block.
Our self-cleaning suction intake filters & strainers enable the use of powerful multi-stage pumps in challenging water conditions.
Any one who has ever faced the problems caused by a blocked basket strainer will appreciate the low maintenance and efficient filtration delivered by Rotorflush self-cleaning strainers. Rotorflush self-cleaning filters and strainers allow pumps to operate in dirty water whatever your circumstances.
The ‘RE’ and ‘AE’ series self-cleaning suction intake filters & strainers have a built in pump motor that drives the backwash separately from the pump output. This is particularly useful if your surface pump has a variable speed motor, as variations in output will not affect the self-cleaning mechanism of your filter.
Rotorflush filters are a robust long lasting alternative to the traditional basket strainer. All but the smallest filters are made from stainless steel – marine grade steel can be provided if required – and they last for years.
These filters are ideal for:
- Protecting irrigation equipment
- Filtration for heat exchange and cooling
- Eel Regulation compliant abstraction
- Municipal fountains
- Open loop heat pump systems
- Anywhere a flow of filtered water is required.
- ………….and much more……….
Rotorflush filters are gently self-cleaning low intake velocity strainers and make ideal eel screens for water abstraction. Our self-cleaning filters are Eel friendly – our products can help with your compliance with the European Commission’s Eel Recovery Plan (Council Regulation No.1100/2007) and The Eel Regulations which now apply in England and Wales. Call for more information about using Rotorflush filters for eel screens..
Larger capacity industrial self-cleaning filters with automatic backwash up to 500 m3 per hour (more if sharing a comnmon outlet and backwash).
All our self-cleaning suction intake filters & strainers can work in fluids containing up to 2000mg / litre total suspended solids, depending on flow rate. They produce a continuous filtered output which prevents downstream blockage to nozzles, valves and solenoids. Maintaining them is easy, infrequent and inexpensive. Their ease of use and minimal maintenance has led to a growing demand for these products across many industries.
Smaller capacity industrial self-cleaning filters with automatic backwash from 30 litres / minute to 90 litres / minute
We offer a range of small self-cleaning filters suitable for domestic and light industrial use. They filter from from 30 to 90 litres per minute.
These robust, reliable and easily installed filters attach to your pump’s suction pipe.
They can be applied to a host of home, garden and light industrial applications and make an ideal pond filter. For use where there is a need to filter, conserve and recycle water contaminated with suspended solids.
