Three new progressive cavity pumps are now available from this manufacturer: the Series C is designed for demanding duties in the pulp and paper, mining and minerals, and chemical industries; the Series D is designed for dosing applications; and the Series E is a compact solution targeting environmental and wastewater applications. The new pumps feature a number of innovations, including the precise Evenwall 3D technology with two-lobe rotor geometry, which offers a more rigid and tighter pumping unit compared to conventional progressive cavity pumps. This makes it possible to reduce the friction between the rotor and stator, which allows for a much lower starting torque and “significantly higher” efficiency, says the firm. A patented shaft design enables its mechanical seal to be quickly replaced without dismantling the entire pump or its drive shaft and coupling. — Larox Flowsys Oy, Lappeenranta, Finland
