How Rotorflush Filterpumps™ Work
See how our filterpumps prevent their self-cleaning intake screen from blocking and how easily they can be installed.
Filterpumps™ pump and filter simultaneously, replacing the need for a water pump with filter, a water pump and filter, a water pump and filter system, and pumps and filters needed to do the same job as a filter pump.
About Submersible Filter Pumps
About Our Submersible Filterpumps™
Rotorflush Filters Ltd manufacture and supply submersible filter pumps with self-cleaning intake screens. The intakes to our pumps have an automatic and continuous backwash that prevents debris from clogging the pump.
This means that its possible to use high pressure centrifugal pumps in very dirty water. It also means that weed and particulate that might block other equipment is screened out of pumped water. Therefore, fountains, spray bars, irrigators, water monitoring equipment and heat pumps don’t get blocked by debris in the water.
The patented design of Rotorflush Filterpumps™ resolves the problem of blocked pumps in dirty water. Pumping and filtration is combined in one easy to install and very low maintenance submersible filter pump.
Our submersible filter pumps with self-cleaning intakes are very efficient, the automatic backwash does not reduce the pump’s output.
Innovative Design
Rotorflush submersible filterpumps™ have their own built-in self-cleaning filter. An additional impeller on the pump motor shaft drives the filter mechanism. This propels the cleaning jets that keep the filter mesh clear of any suspended solids, debris, etc to protect the pump and other equipment.
It is not possible to retrofit these filters to most existing submersible pumps. Therefore, we have selected a variety of high quality pump models for our product ranges.
First, we redesign the pump drive shafts and pump ends. We then add additional impellers. Finally, we fit the filter mesh to produce a submersible pump with a self-cleaning suction intake.

Eel and Wildlife Friendly
Rotorflush filters have a low intake velocity by design. When these filter pumps fitted with 2mm mesh, they can comply with current regulations for Eel recovery.
The gentle backwash maintains a clear filter mesh. This means that our self-cleaning low intake velocity filter pumps and strainers make ideal eel screens for raw water abstraction.
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.

Submersible Filterpumps™
Rotorflush Topaz 7.5 kW submersible filterpump with integral 600 mm diameter self-cleaning suction intake fitted with 315 micron steel filter mesh
Because our filter pumps combine pumping and filtering, they are ideal for filtering waste water and as water filtration pumps and water filter pumps.
Frequently Asked Questions About Submersible Filter Pumps
A filter pump is a pump with a filter on the intake; a Rotorflush Filterpump ™ is our unique award-winning submersible pump with a built-in self-cleaning filter on the pump intake that keeps the intake filter clear and protects the pump from blocking and clogging.
It is a submersible pump with a self-cleaning suction filter on the suction intake of the pump. The self-cleaning intake is built into the pump, and can screen water down to 50 microns without blocking. Rotorflush retro fit an additional impeller in the intake to provide a continuous backwash that keeps the intake screen clear.
The unique design of the Rotorflush Filterpumps™ provides a continuous automatic backwash to the pump intake screen whenever the pump is running. This enables the pump to deliver an uninterrupted supply of filtered water and prevents the filter from blinding and the pump from blocking in dirty water. Pumping and filtering are combined in one easy to install submersible filter pump.
Yes, these filter pumps are more economical to run in contaminated and dirty water because they protect the pump and other equipment from blockages. Money is saved because
- Less downtime
- Maintenance is kept to a minimum
- Self-cleaning intakes protect the pump potentially extending the pump's life
Case Study
How Rotorflush Filterpumps™ Benefited a District Heat Pump Intake System in Liverpool
Chris Hiscock, Sales
Rotorflush Filters LtdKJB Water and Process and Engineering Ltd asked Rotorflush Filters on behalf of their customer to supply submersible pumps with integral self-cleaning intake screens. They wanted to pump river water for the heat pump intake system and screen the water to protect the heat pump installation from getting blocked by any debris weeds or other detritus in the water.
Due to the river Mersey being tidal at abstraction points we were told that the equipment must be suitable for use in salt water and also had to comply with Environment Agency regulations for the protection of eels.
