Cavity pump make-over

Progressive cavity pumps have been subject to a design and performance make-over by Netzsch pumps. Their new-technology, Nemo M Champ range, has a construction with nine major components. New features include a built-in reserve stator and maintenance-free drive chain. Five pumps are available in the range, suitable for use with low to highly viscous fluids, even with solids inclusion, providing capacities up to 85m3/h, at pressures up to six bar. The pumps are able to handle treated and untreated sludge, grease and oil emulsions, industrial effluent and processed food products. As well as environmental and wastewater treatment applications, their liquids handling capabilities make them suitable for chemical, general engineering, processing, mining and quarrying uses, with other applications as diverse as vegetable washing plants. The Nemo M Champ pump capacity is proportional to rotational speed, with reversible flow direction. High suction and pressure capacities are combined with continuous low pulsation conveyance, independent of media pressure or viscosity. The compact pump housing helps to prevent solids sedimentation and has diametrically opposed horizontal flanged ports for pipeline connection.
