Not unexpected Performance Gains from New Fluid Tech's Supa-Stelth Pump Design
The performance characteristics of New Fluid Tech’s (NFT) patented Supa-Stelth pump technology using energy saving Solid Body Vorticity (SBV) often defy conventional expectations. Our current testing with various configurations of a transfer pump, incorporating NFT’s unique design, has yielded results that highlight the counter-intuitive nature of this technology.
In our evaluations, we tested a range of impeller diameters and passageway widths. Notably, each time the impeller diameter was reduced by just 1 mm, the overall pump performance improved. This improvement encompassed multiple metrics—runtime, flow rate, and pressure—indicating a measurable increase in overall efficiency.
In traditional pump designs, such a result would be highly unusual, if not impossible. However, the underlying logic and scientific principles that explain this phenomenon are well-established. For those interested in the technical explanation, we have included diagrams and appendix outlining the physics behind this effect.
This behaviour was not isolated to our current tiny transfer pump tests. Similar results were documented at the Chinese National Agricultural Test Centre in Beijing in December 2024. During trials of one of our larger industrial pumps—a 13.1 kW unit with a 100 mm impeller—performance benchmarks were similarly impressive. The pump achieved a flow rate of 50 cubic meters per hour at a head of 75 meters, with a confirmed efficiency of 79%. It's important to note that this impeller was actually only 2.5 times larger than the 40 mm impeller used in our tiny transfer test pump, and the fundamental performance pattern remains consistent.
In summary, NFT’s smaller impeller pumps utilising Solid Body Vortex (SBV) technology demonstrate increased efficiency and performance as impeller size is reduced—provided the RPM is proportionally increased. This is due to the enhanced tangential angle of the impeller, which accelerates the fluid more effectively. Since acceleration is the source of all force in fluid dynamics, this design characteristic directly contributes to the pump’s superior output
