The Intelligent Inlet Filter: Continuous Self-Cleaning for Pump Protection
Modern fluid systems, especially those handling large volumes of water or containing solids, face a persistent challenge: clogged pumps caused by filter screens blocked with debris. An innovative solution to this problem is the intelligent inlet filter—a technology that utilizes an internal rotor to maintain a clean and efficient filtration process.
How Does It Work?
At the heart of the intelligent inlet filter is an internal rotor mechanism. Powered either by a small off-take from the main pump flow or, in some designs, a dedicated backwash pump, this rotor continuously spins, washing the filter screen from the inside out. Typical designs have the rotor making a full clean of the filter mesh every half second, or about twice per second. This rapid and constant movement ensures that no solids, weeds, or debris can build up on the filter mesh, keeping the entire surface clear and functional.
Key Benefits
- Prevents Pump Blockage: The continuous self-cleaning action keeps the filter mesh free from clogging, ensuring pumps operate efficiently, even in water with high levels of suspended solids.
- Reduces Downtime and Maintenance: By eliminating manual screen cleaning and reducing the risk of pump failure due to blockages, these filters save time and maintenance costs.
- Handles Challenging Water Conditions: Whether in raw water intake, process water loops, irrigation, or dewatering applications, the intelligent filter can tackle conditions that would quickly overwhelm traditional filters.
- Energy Efficiency: Using a portion of the filtered water to power the cleaning rotor means no external power source is required for the self-cleaning mechanism, leading to lower operational costs.
- Easy Removal of Water and Solids: By preventing solids from entering the pump system, these filters also make downstream removal of water and settled solids simpler and more effective.
Applications
- Surface and submersible pump protection
- Industrial water treatment
- Agriculture irrigation systems
- Wastewater and effluent management
- Nanobubble generator systems

Self-cleaning filters prevent pumps from blocking and make aeration more efficient. These pump are also excellent as dewatering filters for drainage of tanks or flooded areas. This video explains the inner-workings of this smart water-filter.
Inlet filters, avoid blocking pumps, keep aquatic-life safe. The filters are mountable to submersible and normal pumps.

Small inlet filter series is the smallest self-cleaning inlet filter (strainer). It filters from 30 to 90 liters / minute and is designed to protect pumps and other equipment. This robust and reliable filter is easy to install. It's compact, lightweight and has simple connections. Great for gardens and light industrial applications where there is a need to filter water. The strainer uses 20 - 25% of the pump's output drive the internal back washing rotor, cleaning the whole screen every ½ second. Debris, wildlife and suspended solids are kept clear of the filter mesh.
The RF200 till RF400 are self-cleaning filters for attachment to the suction hose of surface mounted pumps. They can be fitted with tough nylon filter mesh or sintered stainless steel mesh and can filter from 50 - 315 microns. The inlet filters have a capacity from 220 to 1000 liters per minute. All the filters have an internal cleaning rotor, that is water powered by taking a 'T' off the output of your pump to supply the filter internal rotors. This supply continuously backwashes the mesh screen pushing away anything that might cause it to block. These filters can operate in very dirty water without blocking, reducing the need for settlement tanks and keeping maintenance to a minimum.
The RF600 series self-cleaning intake strainer provides industrial strength, low maintenance filtration for surface mounted pumps. The RF600 series is extremely tough stainless steel self-cleaning basket filters that protect pumps and other connected equipment from blocking and blinding when pumping dirty water. The award winning self-cleaning mechanism in the filters provides a continuous backwash keeping the filter mesh free of weed, debris and other suspended solids. The RF600 can handle 90m3 to 275 m3 per hour.
