A significant disadvantage of a vortex impeller has been its unstable performance, even with low gas content. The hybrid TEO impeller eliminates this disadvantage and as a result, fluids with a gas content of up to 15% can be transported. Good suction performance and a stable activation level guarantee safe operational performance.
Fluids of higher viscosity at first cause a decrease in efficiency and as viscosity increases further, they also cause a reduction in the volume transported and the pressure developed. With the hybrid TEO impeller, in contrast to the vortex impeller pump, a significantly delayed decrease in efficiency is observed – an advantage that pays off especially well in small slurry pumps. Less of a loss of pump performance also means lower energy demands during a necessary re-cooling period, for example during the recycling loop of boring, grinding and sawing emulsions.
