Grundfos KPL axial-flow propeller pumps

Monday, 02 June, 2014 | Supplied by: Grundfos Pumps Pty Ltd

KPL axial-flow propeller pumps are suitable for flood control and other heavy-duty pumping applications. The pumps offer hydraulic efficiency of up to 87%, lightweight design and no clogging.

The company’s Turbulence Optimiser is an expandable rubber ring mounted on the perimeter of pump volute. As water flow and pressure increases, the ring expands and adapts to the pipe, reducing turbulence and efficiency losses. The device has the further effect that misalignment and production tolerances of the column will no longer affect efficiency.

The pump is designed for high flow at low head. With a flow capacity of up to 700 m3/min at up to 9 m head, the product is suitable for flood control as well as other applications, such as raw water intake, stormwater control, wastewater treatment pumping stations, recirculation pumps, aquaculture, water supply cooling systems and amusement parks.

The high-precision, one-piece propeller matches precisely the application. This resolves the potential malfunctions that can occur when having to adjust blades, and there is nothing that can work loose. The back-swept design means rags and solids glide off the propeller, resulting in less clogging. Each pump is individually engineered to suit user requirements and is available in a wide range of variants.

Maintenance is reduced, for example with the back-swept shape of the propeller, making the propeller effectively self-cleaning. An easily replaced wear ring, cable compartment inspection hole and cartridge shaft seal keeps downtime low. For installation and when the pump needs to be lifted, the balanced lifting handle ensures that no damage is done to the pump.

The double mechanical shaft seal is a single-unit cartridge with a back-to-back shaft seal system, providing a sustainable sealing solution with easy replacement in the field, without the need for special tools. Other features include a cable entry seal; cable inspection lid; high-quality bearings; CFD optimised axial volute; and sensors for pump monitoring during operation.
