Abstract

A new storage pump replaced 3 multistage pumps to transport water between the Kreuzeck and the Reisseck power plant sides. Located in the valley of the two reservoirs, it provides impressive performance data for single-stage operation at n = 3000 rpm. Hydraulics already utilised for significantly lower heads are the basis of this pump. The pump was adapted to the new location, and CFD-based development was applied. Within the scope of a model test, the performance data (Q-H-Eta and Q-H-Sigma) were to be confirmed and measured, including the inflow and outflow situation. In addition, the pressure pulsations had to be verified. Finally, installing air vessels should reduce pressure pulsations on the suction and pressure sides. Furthermore, modifications in the bladed areas of the impeller and the guide vane section should enhance this reduction
