About Self-cleaning Basket Filters and Strainers

About Our Self-cleaning Basket Filters

Rotorflush Self-Cleaning Suction Intake Filters & Strainers are for use with surface mounted pumps. They are a welcome alternative to the traditional suction 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.

Low Maintenance, Efficient Filtration

Filter from 14 m³ to over 1000 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 10 mm depending on models. They are used successfully and reliably within the water treatment industry and oil and gas sector and for eel screening in raw water abstraction.

Our filters and screens deliver low maintenance efficient filtration in very difficult conditions.

All our 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.

Drive Backwash Independently out of Pump Output

We also make self-cleaning suction intake filters & strainers with a built-in pump motor that drives the backwash independently of the pump output. This means that the backwash can be continuous and at a constant pressure and flow whether the main pump drawing water through the filter is demanding a high or low flow rate.

This is particularly useful if your surface pump has a variable speed motor, as variations in pump 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.

Eel Friendly, Compliant Solution

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.

Rotorflush Filters Ltd have designed and developed a high open area suction intake to comply with current regulations for the protection of eels.

Increasingly abstraction licences are contingent on the installation of screens and equipment to protect elvers and glass eels.  These measures can be expensive and may even entail civil works to ensure the terms of the abstraction licence. Our intention was to design a suction intake filter that minimised both the approach velocity of water to a screen, and to maximise the open area of our screens to reduce the size of filters required for a given flow rate.

In addition, we believe that our cylindrical filters require less installation than other fixed structures in rivers and lakes, and that their inbuilt self-cleaning mechanism offers lower maintenance and better protection for eels.

Our Eel screens are built using tensioned 2mm woven 316 stainless steel filter mesh. This offers an exceptional open area of around 66%, which enables us to keep the overall area of the filter to a minimum. Flow rates up to 1000 m³ / hr.

Ideal for Use in These Key Areas

  • Protecting irrigation equipment
  • Filtration for heat exchange and cooling
  • Open loop heat pump systems
  • Eel Regulation compliant abstraction
  • EPA Rule 316(b) compliant cooling water intakes
  • Municipal fountains
  • Recycling process water
  • Sample filtration
  • Anywhere a flow of filtered water is required.

Frequently Asked Questions About Self-cleaning Intake Filters

A Rotorflush a self-cleaning intake filter or strainer connects to the suction pipe of a surface mounted water pump. They are a robust long-lasting alternative to the traditional basket strainer - all but the smallest filters are made from stainless steel.  All our filters and strainers are self-cleaning automatic backwash filters, with in-built cleaning rotors that continuously backwash their mesh screen to prevent blocking and blinding.

Traditional basket strainers get blocked easily if the water being pumped contains any debris, weed, leaves or other particulate. The Rotorflush self-cleaning mechanism, however, uses the power of the water being pumped to continuously clean and clear the filter mesh. This means that the basket strainer can pump for much longer without being cleaned while protecting your pump and any further connected equipment from blocking.

Time and money can be saved because our strainers and filters deliver low maintenance and efficient screening in difficult water conditions.
