The KPL axial-flow propeller pump is designed for high flow at low head. Another innovation, available as an accessory, is the anti-cavitation cone, an innovative solution for avoiding the build-up of vortices and cavitation in the pumps. The Turbulence Optimiser is standard in all KPL axial-flow propeller pumps and has the further positive effect that misalignment and production tolerances of the column will no longer affect efficiency. As water flow and pressure increases, the rubber ring expands and adapts to the pipe, reducing turbulence and the efficiency losses this causes. The Turbulence Optimiser is an expandable rubber ring mounted on the perimeter of pump volute.
Grundfos has developed the Turbulence Optimiser, an innovative solution to this problem that increases the hydraulic efficiency by up to two percentage points. As the flow and pressure increases, so too does the turbulence, increasing efficiency losses further. Traditionally, axial-flow propeller pumps lose efficiency from the turbulence generated in the gap between the pump volute and the column pipe. Best-in-class hydraulic efficiency of up to 87%.The range of KPL axial-flow propeller pumps offers: “The efficiency gains from the Turbulence Optimiser show our commitment to finding solutions to real-life issues facing owners and operators that give tangible benefits.” “At Grundfos, our focus on energy efficiency and reliability for critical applications helps water utilities and individuals avoid disruption in their daily lives,” says Jan Pedersen, Sales Development Director, Grundfos. The emphasis on stormwater, surface and rainwater control has resulted in increasing demands for reliability, robustness, reduced energy consumption, and simplified maintenance. Increasingly, Water Utilities need to cope with the consequences of extreme rainfall and runoff events.
