Popular applications for progressing cavity pumps are the food, pharmaceutical, cosmetic and chemical / biochemical industries. In this industries special hygienic progressing cavity pumps are required as this sensitive environment allows no contamination and the media must be specially protected to prevent the growth of bacteria and pathogens. The pumps must be designed and manufactured to meet the high requirements of hygiene and cleanliness inside the pump and also at the outside of the housing. These requirements are defined by a range of guidelines, from 3-A Sanitary Standard to the requirements of the US Food and Drug Administration (FDA). A continuous, pressure-stable, gentle and low-pulsation conveyance as well as a speed-proportional metering of the media by the pump can be ensured by progressing cavity pumps. This is very important because most of the pumped media like yoghurt or liquid egg, are very susceptible to shear and therefore rely on a very gentle promotion, so that their consistency is maintained. In order to meet the wide range of fluids and applications in the food industry, NETZSCH offers a broad range of sizes and designs.
