2 Grundfos Mixers and flowmakers A wide variety of applications Full range of efficient and reliable submersible mixers and flowmakers for wastewater and sludge The Grundfos range of mixers and flowmakers is ideally suitable for a variety of applications in wastewater treatment, industrial processes, construction, agriculture and aquaculture. Grundfos offers a complete range of extremely dependable and highly efficient submersible mixers and flowmakers for a variety of processes in wastewater treatment plants. The mixers and flowmakers are designed for use in the toughest environments. The mixers and flowmakers are of a modular design, which makes them easy to maintain and service. All parts are manufactured from specially selected materials, and each component is thoroughly tested for reliability and durability before assembly. Direct or planetary gear drive The Grundfos range of mixers is available with either direct driven or planetary gear driven propellers, depending on the model. The stainless steel or polyamide propellers are designed for high efficiency even under heavy-duty operating conditions. Powerful advantages > Lifelong reliability Grundfos mixers and flowmakers are of a robust construction, designed for continuous operation under the most difficult operating conditions. > Energy-saving efficiency Modular motors and planetary gear systems make the mixers and flowmakers highly dependable and very efficient with low operating costs. > Easy maintenance State-of-the-art design and sturdy construction reduce wear and tear and allow for quick and easy once-a-year maintenance.

3 State-of-the-art design - with many unique features Watertight cable entry Watertight to 30 metres. Protects the power cable with a soft shaped sealing ring. The cable entry complies with the specifications for explosion-proof machinery. Insulation of winding threads Special protection of the windings, carefully made by hand, ensure full protection also after long periods of operation. Planetary gear The best solution to transfer axial forces, thus the high efficiency of 97%. Slim design provides an optimal hydrodynamic shape. Shaft sealing The radial shaft sealing rings protect the mechanical shaft seal system from abrasive parts. During maintenance only the less expensive radial shaft sealing rings need to be changed. Stable motor bracket Galvanic separation prevents any electro-chemical corrosion. The power cable is secured against tearing away by a strong holding clamp. Propeller hub and shaft Change of propeller during maintenance is quick and easy. Special tools are not required. Dielectric oil Improves the heat transfer compared with conventional air-cooling. The motor has a higher efficiency and there is no problem with humidity formation. Add to this, it allows a more compact design. Active electronic leak sensor Indicates possible liquid in the gear housing. Even the smallest quantity will be quickly detected. Thus service can be carried out before any damage is done. Two bearings Computer designed propellers The hydrodynamically optimised propellers have been designed by computer animation. The three-dimensional free areas increase efficiency and prevent clogging. The shaft rests on two roller bearings, which accommodate both axial and radial forces present in mixers and flowmakers. 4 5 Details >

The selection charts (curves) for the Grundfos mixers are based on square and circular tank shapes. The selection charts (curves) for the Grundfos Flowmakers are based on activated sludge and a velocity of 0.3 m/sec., and a relation between tank length and width of 4:1.
