High volume self-cleaning filterpumps – up to 2500 lpm

Submersible Pumps with a Self-cleaning Intake Filter – up to 2,500 litres a minute

High volume self-cleaning filterpumps for use in very difficult water conditions

Our high volume self-cleaning filterpumps are for moving large volumes of water in harsh and dirty conditions. They are excellent in conditions where basket strainers would normally block.  The filter mesh stays clean as a result of the effective self-cleaning filter.   They also protect spray bars, irrigation nozzles and other connected equipment.

This means that you can pump and filter dirty water that would normally defeat a conventional centrifugal pump.   This is because a continuous backwash keeps the intake screen clear.  So these high capacity submersible filterpumps operate without the high maintenance associated with usual intake screening.

One easy to install ‘plug and play’ unit combines pumping and filtering.   And now our filterpumps can move even more dirty water.

Submersible Pumps with self-cleaning Intake Screens – to 150m3 / hr

Rotorflush Filters Limited offer a wide range of 1000 litre / minute plus capacity filterpumps. We always endeavour to meet the ever growing needs of our customers.  More and more people are discovering the benefits and convenience of our award-winning self-cleaning suction intake filters and filterpumps.  For this reason we are continually improving our product ranges to meet the wide variety of applications and industries we now supply.

Submersible pumps with a self-cleaning intake are used:

  • throughout the water industry
  • on farms for removing dirty water and for irrigation
  • to protect heat pump installations
  • clean up industrial waste water for disposal
  • and for raw water abstraction


Full details of our high volume filterpumps can be found on the RUBI range, Cobalt 600 range, Topaz 600 range and Sapphire 600 high pressure range web pages

Cobalt 600 General Purpose Filterpumps

The Cobalt 600AR’s are a range of filterpumps with self-cleaning intakes offering low to medium head pumping and intake screening for general purpose use. So they are iIdeal for Irrigation, de-watering, supplying fountains and managing waste water.

Cobalt 600 filterpumps use fine or coarse intake screens. These filterpumps protect the pump and any downstream equipment from blockage, reducing maintenance to a minimum. Consequently maintaining our submersible pumps with self-cleaning intakes is easy, infrequent and inexpensive. Their ease of use and minimal maintenance has led to a growing demand for these products across many industries.

Cobalt general purpose filterpumps offer flow rates up to 1,750 litres / minute and up to 30m head.

High volume self-cleaning filterpumps - medium head Topaz filterpump

Topaz 600 High volume Self-cleaning Filterpumps

The Topaz 600AR range of filterpumps have 316 stainless steel suction intake screens.  This range of filterpumps offers low medium and high pressure pumping in harsh or saline environments.

The cast iron and stainless steel pumps are complemented by our highly effective self-cleaning intake screens.  These filterpumps are therefore ideal for for heavier industrial use.

The Topaz range of filterpumps offers flow rates up to 1500 litres / minute and up to 35m head.

“A major water company needed to provide a means for spray cleaning its first stage sewage separation screens. Potable water could not be used in such an applications because of the danger of cross supply contamination and excessive cost, so we had to arrange for a suitably filtered continuous supply from the treatment works’ “final effluent” output.

While this is suitable for discharging into the water course, it nevertheless contains enough solid particles to require a normal filtration system to be cleaned at frequent intervals. We therefore specified a Rotorflush Filter-pump which continuously cleans its own filter without the need for manual intervention.

Initially, the customer specified water pressure turned out to be more than necessary for the job, but Rotorflush responded very efficiently by quickly modifying and returning the unit, which has since functioned perfectly with minimal attention.”

Sapphire 600 High volume Self-cleaning Filterpump

The Sapphire 600AR range of filterpumps offer high head and high volume flow rates.  This powerful range of centrifugal filterpumps offers pressure pumping in harsh dirty water conditions thanks to its built-in self-cleaning intake that protects the pump impellers from debris.

Because of their cast iron and stainless steel construction these filterpumps with self-cleaning intake screens are ideal for general industrial and agricultural applications.

The Rotorflush Sapphire 600 high volume filterpump offers flow rates of up to 1500 litres / minute and up to 140m head.

 RUBI heavy duty filterpump - a mere 1000 litres a minute.

Need less capacity?

Lower capacity industrial self-cleaning filter pumps with self-cleaning intake – from 80 to 1000 litres per minute

All our pumps and filters 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. In other words 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 filterpumps are ideal for sampling water for analysers, and pumping and filtering raw water ahead of domestic and small industrial open loop heat pump installations.

Proototype Eel screen - High volume self-cleaning filter for Eel protection

Need More capacity?

Our large capacity, high open area, self-cleaning eel screens for use with surface mounted pumps can screen up to 1000m3 / hr.

As with all our filters they produce a continuous filtered output which keeps the screen clear, protects pumps and prevents downstream blockages.  The same ease of use and minimal maintenance has encouraged their use in more and more industrial sectors. Large capacity, heavy duty industrial submersible pumps and intake screens that don’t block in difficult conditions are now in demand from the oil and gas sector, water companies, agriculture, food manufacturing and processing, and the power industry.

Eel and wildlife friendly

The Environment Agency can place conditions on raw water abstraction licences in order to protect eels and other wildlife. Typically, this can be a constraint on the velocity of abstraction at a raw water intake and on the mesh size a used to screen the intake – usually 2 mm aperture or less.

Rotorflush filterpumps fitted with 600 mm diameter intakes comply with EA Eel regulations requiring an intake velocity of 0.1 metres / second up to the following flow rates:

Cobalt, Topaz and Sapphire ranges with 600 mm diameter intakes fitted with 2 mm mesh: Up to 94 m3 / hour

Protecting eels by complying with EA regulations on the protection of the European eel
Rotorflush filters have a low intake velocity by design. The gentle backwash maintains a clear filter mesh. This means that our self-cleaning low intake velocity filterpumps and strainers make ideal eel screens for raw water abstraction in both fresh water and seawater .

Rotorflush filters are Eel friendly – our products can help with your compliance with the Environment Agency’s Eel Recovery Plan (Council Regulation No.1100/2007) and The Eel Regulations which now apply in England and Wales.

So call for more information about using Rotorflush filters for eel screening.

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.
