The pharmaceutical and cosmetics industry is characterised by health and body care. Many products are highly viscous media such as cremes, lotion, vitamins, toothpaste and more. Handling these media is subject to the most stringent hygiene requirements during the process. This is one reason why the pumps of the CS series have proven particularly well suited for conveying and metering these products. In the case of applications in sterile areas, the surface quality as well as the cleaning capability of the pump systems play a crucial role - a functional requirement which the CS series meets. In the pharmaceutical sector sensitive media can, therefore, be conveyed without reservations using a Helix progressive cavity pump.
