Process integrity, recipe constancy and product safety play a decisive role in the pharma, food, and cosmetic industries. Lewa, a manufacturer of pumps and systems for a variety of industries and segments, will present a portfolio at this year's Technopharm in Nuremberg, Germany from September 30 to October 2, that includes not only different diaphragm metering pumps, rotary lobe pumps, progressing cavity pumps, centrifugal pumps and air-operated double diaphragm pumps, but also customer-specific chromatography systems.
For example, a Lewa Ecodos hygienic with Intellidrive will be exhibited, as well as an Ecoflow hygienic with the reliable M900 diaphragm pump head. Both hygienic pumps are characterised by the fact that the product chamber is safely isolated from the gear side without seals. Even for longer-lasting processes, this allows the pumps to remain hermetically tight and leak-free. Pump hydraulics and the metered fluid are consistently separated by the sandwich diaphragm. If one of the layers of the diaphragm is damaged, the increase in pressure between the diaphragm layers leads to an automatic fault message. This permits very high process reliability.
Both the Ecodos and the Ecoflow hygienic can also be used as multiplex pumps for recipe metering. For this purpose, multiple pump drives are mounted on a single drive shaft. The metering volume can be varied reproducibly and cost-effectively by frequency regulation of the shared drive motor and/or individually using manual or electrical stroke adjustment of each specific pump head.
