Tests carried out by the Fluid Mechanics, Acoustics and Fluid Machinery (SAM) Institute at the Technical University Kaiserslauten have confirmed that Supa-Stelth pumps from Brisbane-based New Fluid Technology (NFT) are among the most energy efficient pumps available with an exceptionally high NPSH.
The report tested the performance of the Supa-Stelth pump for its efficiency and net positive suction head (NPSH). The NPSH level shows how well a pump resists cavitation, one of the major reasons for pump failure and maintenance issues for companies.
The report stated that the efficiency of the pump was around 75% and the hydraulic efficiency of the wet end was around 71%, which it concluded was extremely high when compared with other similar pumps. It also stated that NPSH values exceeded expectations.
NFT’s Supa Stelth pumps are made in China by Purity Pumps and range from 600-7,500 watts. Although sometimes referred to as an impeller pump, the company says that with Supa-Stelth pumps, the impeller simply primes the pump and then at about 380-400 rpm it snaps into a solid body vortex (SBV) which gives the pump its superior performance.
