Anti-Clogging Pumps
Aquatic Control Engineering (ACE) is the UK supplier of Pentair Fairbanks Nijhuis XRW Series Pumps — a next-generation solids handling solution built for today’s wastewater challenges. Featuring the innovative Xcentric™ Impeller, the XRW range delivers exceptional clog resistance, reduced energy use and long-term operational reliability.
Designed for modern wastewater containing wipes, fibres and problematic solids, the XRW Series ensures efficient, dependable performance while lowering maintenance and lifecycle costs.
Engineered for Clog-Free Performance
The patented Xcentric™ Impeller removes traditional vane leading edges and uses a smooth, tapered conical profile. This allows wipes, fibres and solids to pass freely through the pump — significantly lowering blockage risk and reducing unplanned maintenance.
The result is a pump that remains stable, quiet and efficient, even in demanding wastewater environments where conventional designs regularly clog.
Proven Manufacturers
Pentair Fairbanks Nijhuis is a global leader in high-capacity pumping equipment, with installations operating in wastewater works, flood-defence structures and major municipal networks worldwide.
The XRW Series was named 2024 Sustainability Product of the Year, recognising its ability to reduce energy consumption, minimise clogging and offer an environmentally preferable alternative to chopping or grinding pumps.
Cost-Efficient Retrofitting
The XRW’s compact dimensions and versatile mounting configurations make it suitable for both new build and retrofit schemes. Many installations require minimal civil modifications, lowering project costs and reducing installation time.
This makes the XRW Series an ideal upgrade for sites experiencing recurring clogging, high maintenance demand, or rising energy consumption.
About XRW Series Solids Handling Pumps
The XRW centrifugal pump is built around Pentair’s patented Xcentric™ Impeller, featuring a conical, open flow passage designed to pass wipes and solids without entanglement or obstruction.
Key engineering features include:
• Hardened steel adjustable wear ring
• Double mechanical seals that require no specialist tools
• Ductile cast iron casing for harsh environments
• Inspection opening for simple internal checks
• Permanently lubricated bearings for reliability
These pumps deliver powerful hydraulic performance with significantly reduced clogging, making them ideal for wastewater, sludge and surface-water pumping stations.
Why Choose XRW Series Solids Handling Pumps
01
High-Efficiency Solids Transport
The Xcentric™ Impeller maintains smooth, stable flow through the pump, even when handling wipes and fibrous materials. This enables high performance across wastewater networks, sewage lifting stations, booster stations and sludge handling systems.
02
Reduced Maintenance
With fewer clogs, minimal vibration and robust component design, the XRW delivers longer service intervals and lower whole-life costs — vital for resilience and operational reliability.
03
Versatile Application Range
The pumps operate effectively across wastewater, screened sewage, sludge, surface water and industrial effluents. With horizontal and vertical orientations available, the XRW integrates easily into many site layouts.
04
Reliable Pressure & Flow Generation
The combination of the impeller geometry, engineered casing and hardened wear ring provides strong pumping performance. The XRW range covers flow rates up to 3,000 m³/h and heads up to 60 m, making it suitable for a wide range of municipal and industrial duties.

Frequently Asked Questions
The patented Xcentric™ Impeller eliminates standard vane edges and uses a tapered conical profile. This geometry allows wipes, fibres and solids to pass through without binding or obstruction, significantly reducing clogging compared to traditional impeller designs.
Yes. The XRW Series was specifically designed for today’s wastewater, including high levels of wet wipes and fibrous material. Many operators switch to the XRW to reduce blockages and improve site reliability.
In most cases, yes. The pump’s reduced capacity drift, smoother operation and efficient impeller design typically result in lower energy use. The smaller pump size compared to equivalent models also helps reduce power demand.
Absolutely. With both horizontal and vertical configurations, IEC B5 motor compatibility, and DIN/ANSI flanges, the XRW often fits into existing civils with minimal modification. ACE can assist with design and retrofit integration.
Double mechanical seals, an inspection opening, permanently lubricated bearings and a hydraulically adjustable wear ring allow for simpler servicing and longer intervals between maintenance tasks.
