LEWA presents wide-range speed control for Ecodos pump

06 April 2018

At Hannover Messe 2018, LEWA GmbH is presenting a new wide-range speed control for the proven Ecodos pump series, which makes it possible to achieve a stroke rate from 1 to 210 strokes per minute without needing to change the stroke length. The system is primarily suitable for solutions with multiplex pumps in the low-pressure range up to 20 bar, while also enabling a linear performance curve. Furthermore, the pump experts will be displaying a NIKKISO centrifugal canned motor pump and a pulsation/cavitation demonstration stand, where the pumping operation of a LEWA Ecoflow will be demonstrated live. 

For use in the food and pharmaceutical industries, all wetted materials of the LEWA Ecodos pump series meet the requirements of the FDA, USP Class VI and the EU directives for the food industry.

Moreover, the 1.4435 stainless steel applied here is the suitable choice for most requirements, as pump heads made of this material are designed for pressure ranges up to 20 bar and fluid temperatures of up to 80 °C. The pump head is made of PP or electropolished stainless steel with a surface roughness of < 0.5 µm in the hygienic variant. This makes cleaning the surfaces of wetted parts easier. The geometry of the pump head is designed in a way that residue from process media is reduced to a minimum.
