Industrial wastewater treatment & reuse
Grundfos submersible, direct driven AMD mixers are designed for mixing, i.e. homogenisation and suspension of low/medium viscosity liquids in small tanks and pumping stations.
The Grundfos range of horizontal, submersible mixers is designed for applications involving the mixing, i.e. the homogenisation and suspension, of low- to medium-viscosity liquids. Primarily designed for mixing and flushing applications in pump pits/tanks, the AMD mixer keeps solids in suspension and flushes them down, thus replacing the conventional flush valve. The motor housing is made of stainless steel and the propeller of highly wear-resistant polyamide. The propeller is self-cleaning.
The totally enclosed four-pole, three-phase, squirrel-cage induction motor is star-connected for direct-on-line starting. The dielectric oil in the motor distributes and diverts the heat, preventing the ingress of moisture. The built-in thermal switch disconnects the motor at 100 °C and reconnects it after cooling. The motor must be protected against overload by means of an external motor starter. Direct-on-line starting of motors is intended, unless otherwise required by the local electricity provider.
