Rotory Pump
Small volume, large flow, high lift, suitable for long-distance and high-resistance quantitative transportation.
All parts in contact with materials are made of stainless steel 316L that meets hygienic standards, and the seals are made of non-toxic rubber. Reliable rust resistance and non-toxic sealing ensure safety and hygiene.
The streamline structure of the rotor and the absence of dead spots and non-metallic parts in the rotor chamber avoid contamination of the conveyed material, and are fully suitable for in-situ CIP cleaning and steam sterilization.
The two rotors rotate synchronously in opposite directions, creating a high vacuum and discharge pressure. The two rotors divide the rotor chamber into several small spaces and operate in the order I-II-III-IV.When it runs to position I, only the inlet is filled with medium; when it runs to position II, part of the medium is closed in chamber II; when it reaches position III, the medium is also closed in chamber III; when it reaches position IV, the inlet and outlet chambers are connected , the medium is transported to the discharge pipeline.
