Liquid ring pumps hygiene

A hygienic self-priming liquid ring pump in a newly developed range for the food and pharmaceutical industries.

The AS Series is a hygienic, self-priming liquid transfer pump for the food and pharmaceutical industries. The pump is designed for hygienic applications where the incoming liquid may contain gas or air, where foaming liquids need to be handled, or where the suction tube is only partially filled. The liquid ring principle allows the pump to maintain a vacuum under varying suction conditions. After the initial filling with liquid, some liquid remains in the pump, ensuring rapid self-priming even when the suction line is empty.

Standard-series sanitary liquid transfer pump with extremely high suction capacity down to −0.7 bar. Robust design with front-mounted DIN seals. Typically equipped with IEC motors, ATEX-certified motors, or hydraulic drives. Suitable as a loading and unloading pump for sugar solutions, solvents, and oils. Also used as a powder mixing pump and for CIP returns.

The CNH series is a highly hygienic, self-priming centrifugal pump from CSF for the food and pharmaceutical industries. The series is based on the CS series and has been developed for applications where good suction capacity, high efficiency, low noise levels, and a service-friendly design are key requirements. The pump is suitable for, for example, feeding raw materials, solvents, and similar process fluids. Its unique design and patented drainage system allow the pump to handle liquids containing air.
