better together Why Mixers? Essential components of water treatment and purification plants, the new Zenit mixers share the stylish looks, reliability and new-concept high-efficiency motors of the UNIQA range. The low propeller rpm, necessary in applications with sludges containing high solid concentrations, is achieved by means of a rugged planetary reduction gearbox rather than motors with a high number of poles, for greater mechanical reliability. Submerged mixers are the most practical, efficient solution for mixing liquids in water treatment and purification plants. Suitably installed...

better together One range, a thousand applications Zenit ZMD and ZMR series mixers can be used in equalisation, denitrification and homogenisation processes in industrial and civil plants. Their construction characteristics make them rugged and versatile, ideal for any application. The ZMD and ZMR range of mixers is built on a modular criterion in which high-efficiency motors evolved from the UNIQA units are coupled with propellers with different shapes, sizes and materials. This means greater flexibility when selecting the product, which can be configured specifically for the application,...
