Submersible Filterpumps™ with Self-cleaning Intakes

Submersible Filter Pumps with Self-cleaning Intakes

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 filterpumps™ with self-cleaning intakes are very efficient, the automatic backwash does not reduce the pump’s output.

Our filter pumps are submersible and continuously rated

Furthermore, they all 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.

The filters on our pump inlets have a large open area and a low velocity intake. When these filter pumps fitted with 2 mm mesh they can comply with current regulations for Eel recovery.

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.

Submersible Pumps with Self-cleaning Filters – 220 L/min

Three ranges of high quality submersible pumps with self-cleaning filters built-in. The pumps prevent the pump and filter from blocking because they are fitted with self-cleaning filters. They use a continuous automatic backwash to keep mesh clear and deliver an uninterrupted supply of filtered output. They are ideal for use in water contaminated with suspended solids.

The self-cleaning inlet filters are capable of filtering up to 14 cubic metres per hour. They have screen apertures ranging from 60 to 315 microns. They protect the pump and other equipment from blockage thereby extending pump life and reducing maintenance to a minimum. 

Submersible Pumps with self-cleaning Intake Screens – to 60 m3 / hr

Rotorflush Filters Limited offer a wide range of 1000 litre / minute capacity filter pumps to meet the ever-growing needs of our customers.  Our versatile submersible filter pumps offer low, medium and high pressure industrial pumping for a range of applications.

Submersible pumps with a self-cleaning intake are used:

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

And much more. We are continually improving our proucts to meet the wide variety of applications and industries we now supply.

Full details of our 1000 litre / minute filter pumps can be found on the RUBI, Sapphire, Cobalt 400  and Jasper 400 web-pages.

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

Rotorflush Filters Limited offer several high capacity 1000 litre / minute plus filter pumps.  More and more people are discovering the benefits and convenience of our award-winning self-cleaning suction intake filters and filter pumps.  For this reason, we continually endeavour to meet the ever-growing needs of our customers.

Technical advances in many industrial sectors have created a growing demand for pumps that can operate efficiently and with minimal maintenance in often very dirty water. Regulations and directives for protecting fish and wildlife have also created a demand for our self-cleaning intakes for use in raw water and for abstraction for cooling systems.

Our higher capacity pumps are capable of moving up to 150 m3 / hr and offer up to 140 metres head. Since their introduction in 2018 they are proving a popular choice for agri-industrial water source heat pump applications.

Full details of our high volume filter pumps can be found on the RUBI, Cobalt, Topaz and Sapphire web pages

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 filter pumps 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.
