Rotorflush products are used for screening and pumping process and waste water in many industries including, paper-mills, quarries, desalination plants, distillers, power stations, food manufacturers, Heathrow Airport - and many more.
The cost of water, water treatment and monitoring, and waste water disposal can have a significant impact on production costs. Considerable savings can be made by re-using and recycling water, and more efficiently treating waste water.
Rotorflush self-cleaning filter pumps and strainers provide a low maintenance means of pumping and filtering water. Our products are particularly useful for removing debris and solids in suspension.
RUBI LH-800 range filterpumps™ are durable, cast iron, high-pressure water pumps with stainless steel self-cleaning suction intake screens, suitable for heavy industrial applications and dirty water conditions. They will pump and screen up to 390 m3 / hr, and have a maximum head of 17.5 bar.

The Rotorflush GT200 Liquid Solids Separator provides an easy way to remove and dispose of particulate and solids when moving contaminated water. As water flows by gravity or is pumped into the GT200 liquid solids separator, the separator simultaneously filters out debris and pumps filtered water onwards. Debris and particulate left behind is purged from an outlet below the separator as required, either manually or automatically on a timer.

Self-cleaning filter pump. The O1608-16 sample pump is a low head submersible filter pump with an integral self-cleaning filter for use with on-line analysers and dosing systems. It delivers a filtered output of water which prevents blockage to nozzles, valves and solenoids. Sample water can be screened to 60 microns and pumped simultaneously.

Many industrial processes leave water dirty; where the contamination is primarily comprised of solid material in suspension, Rotorflush self-cleaning filters and filter pumps can quickly and efficiently separate particles so that water may be re-used. Here’s a great example from one of our customers:
“We were very happy to recommend Rotorflush’s filterpumps™ for an installation in a glass factory where a re-circulating water spray system is used to cool the molten glass during production. The filter and spray nozzles were daily becoming blocked with particles of glass and scale.
The process environment is extremely hot and hostile, nonetheless we decided to fit a Rotorflush filter to the existing pump and as a result, production now proceeds without interruption.”
Rotorflush self-cleaning filters are being used to remove lint and other debris from wash-water in laundries, allowing for heat recovery, re-use and lower waste water disposal costs.
How to Clean the Suspended Solids From a Dirty Water Tank
Dirty water in settlement tanks, IBC containers full of dirty water, rainwater harvesting tanks, sumps and other water storage areas from where water is pumped for use can all benefit from an effective self-cleaning filter on the pump suction intake. This will prevent blockages and keep things running smoothly.
The dirty water in your tank can be filtered and pumped out for use elsewhere, while the pump and filter stay clear preventing any downstream equipment from becoming blocked. But…….everything filtered out is still in your tank.
Here’s a neat solution to crud accumulating in storage and settlement tanks. A self-cleaning filter can be used to collect suspended solids in a smaller container than your storage tank. The smaller tank can be purged or pumped out with a solids handling pump as debris accumulates. This is more water efficient than periodically draining a much larger tank.
Rotorflush Filters Ltd have developed an automatic self-cleaning filter system specifically to filter sample water for analytical equipment. Development began in response to a requirement to measure levels of chemicals in white water at paper mills, enabling the output to supply analysers without blocking the cells. Output of the system is from 0 to 2 litres / minute.
The system is now used widely in the UK water industry for screening sample water for continuous wet chemistry analysis – primarily for ammonia, chlorine and phosphate analysis. The self-cleaning filter screens down to 60 microns and allows sampling from a static head in a fast loop system. The output flow is not interrupted and the intake filter self-cleans to prevent blocking.
The system is particularly useful for systems using dosing pumps and where there is a need to continuously monitor water quality. The self-cleaning filter keeps the filter mesh clear to deliver low maintenance sampling and filtration, particularly useful in food manufacturing and processing.
We also supply submersible sample pumps with built-in self-cleaning intakes for use directly in a water supply. Both products are ideal for supplying filtered sample water for to analysers.
Rotorflush products allow water contaminated with solids to be screened and pumped while minimising the risk of blinding or blockage. This means that our self-cleaning filtration products can be used for
or any industrial process where particulate needs to be screened out of water for recycling, reuse, or disposal. Our products are often used in purge tanks to remove contaminants so that water can be reused.
All of our self-cleaning intake screens are specified to suit required flow rates.
Filter pumps are recommended based on the flow rate and pressure needed, taking into account any pressure losses through your set-up.
Intake strainers and screens are specified according to the maximum flow through that is required.
Consideration should be given to what mesh size you need - top tip, go for the largest mesh size you can get away with to minimise maintenance.
Yes, environmental regulations may determine the type of filter pump or strainer to be used. Products can be sized to account for Eel Regulations or EPA rule 316(b) if applicable, so that intake velocity and mesh size meet regulatory requirements.
We wish it were possible to screen all types of fluid with our products, but there are limits. Rotorflush products work very well in dirty water or other fluids where the viscosity is the same or very close t that of water. So, no sludge.
Oil and grease in the water will also limit the efficacy of Rotorflush products - grease and oil combine readily with fibrous material and is extremely difficult to screen once it begins to accumulate.
Yes – because our products pump and filter directly from a dirty water source, there is less need for expensive in-line filtration.
All our products have built-in self-cleaning back-washes that prevent intake screens from blocking, keep pumps clear and protect other connected equipment. This reduces maintenance, minimises downtime and can extend the life of pumps. Screening water for reuse can also cut costs.
Case Study
Naomi Way
Rotorflush Filters LtdThe site had 3 intakes which at the time had traditional basket filters. In addition to this, the filters were preceded by a large screen. Grants told Rotorflush that in the autumn the significant leaf fall required one of their workers to clear the screen of leaves “24/7”.
