Choosing the Right Rotorflush Filterpump™ for your Project, Use or Application

Help choosing your Rotorflush Filterpump

There are many types of water pump, most have been designed for particular uses and industrial contexts. In addition, these are available in a range of sizes offering differing flow rates and pressures. Rotorflush Filterpumps™  are exclusively electric, centrifugal, submersible water pumps. All our pumps have a built-n automatic backwash system to keep their intake screen clear. 

Rotorflush offer general purpose pumping and screening of natural and industrial waste water, providing low maintenance use and installation, and, depending on your flow rates, screening can be as fine as 50 microns.

This page looks at Rotorflush self-cleaning filterpumps, to help you best meet your requirements. 

First - the unavoidable truths about screening and filtering water are:

• Filters and screens always clog and block sooner or later
• This shows that they are doing what they are supposed to do.
• Unblocking pumps, screens and filters is usually a hassle, unpleasant, and the less often you need to do it, the better.

Rotorflush Filters Ltd have developed a range of products for pumping and screening dirty water that all incorporate their patented self-cleaning mechanism. This hugely reduces the frequency of filter screen maintenance, meaning far less blocking and clogging of pumps, screens and other equipment. The truths above, however, do still apply.

The uses for Rotorflush submersible filterpumps™ are numerous, in short any application that requires any type of water to be pumped and screened. For example, farms, factories, and water treatment works use our filterpumps. Water companies use our filterpumps to to wash down intake screens and to sample effluent. Farmers use our  filterpumps to pump farmyard run-off back to land and for taking water from rivers and ponds for irrigation. Others use our pumps for keeping fountains running, for cooling water, or anywhere that dirty water needs to be pumped without blocking pumps and other equipment.

It can be tricky sorting out the best pump to meet your requirements. Fortunately, we have a wealth of knowledge and expertise in the installation and use filterpumps. 

So whether you are pumping out a tank or sump, taking water from a lake, pond, river, lagoon, or moving industrial process water, or supplying a fountain or water feature, Rotorflush Filters Ltd has a product that will let you screen and pump simultaneously.

The Basics - Submersible Pumps with Built-in Self-cleaning Intake Filters

Rotorflush Filterpumps™ are submersible pumps that screen and filter dirty water as they pump. Their impeller sets are protected by a self-cleaning intake screen that self-cleans to avoid clogging, protecting the pump and any connected equipment - irrigation equipment, spray bars heat exchangers etc - from becoming blocked by particulate in the source water.

Hassle-free pumping and screening in one complete unit.

Rotorflush filterpumps are industrial submersible pumps and come in a range of capacities. If you need a filterpump but are unsure which of our many modes will suit your requirements we can help.

If you can answer a few questions about what you wish to achieve with a pump we can help. Please tell us:

• The static head (the height above water level you wish to pump)
• The pipe run (distance) from the pump to where you need the water
• The diameter of your pipe
• The pressure you need at the point of delivery
• The flow rate or amount of water you need
• How finely you need to filter (top tip, always go for the largest size mesh you can get away with – reduces maintenance)
• What kind of debris etc you are trying to avoid or remove
• Description of water quality (brackish, seawater, silty etc).

This information enables us to specify the most suitable pump and mesh size for the job in hand.

What Rotorflush Filterpumps Can and Can't Do

Filtration can be problematic. It is important to know what you wish to filter for, and equally what your dirty water filter can handle. This is because most dirty water contains a mix of contaminants, unless it is dirty as a result of a specific industrial process. Therefore, the type of filter will often depend on the location, water quality and what it is in the water that causes the most trouble.

Rotorflush Filterpumps are widely used across many industry sectors. They are particularly efficient at separating out organic material and suspended solids from water. For example weed, leaves, and other debris, fibrous material, dairy run-off fo example.  The self-cleaning pump intakes are ideal when the contaminated water is the same or as close as possible to the viscosity of natural water.

The Rotorflush self-cleaning mechanism is not designed to handle sludge, raw sewage, or water contaminated with oils and grease.

Compare Rotorflush filterpumps to find the right screening and pumping product for you. Rotorflush filterpumps are submersible water pumps with a built-in self-cleaning intake screen. They are uniquely different from standard submersible pumps. These pumps screen and filter out debris, weed, suspended solids in water as you pump. The intake self-cleans as you pump so that the intake screen stays clear and the pump does not block., preventing the pump.  Which Rotorflush Filterpumps™  will suit my needs?
