Progressive cavity pumps are becoming increasingly popular in the pharmaceutical industry. They represent a process-safe, low-shear and high-precision dosing of viscous products. They are already successfully used in production facilities, in both the conveying and the filling process. High-performance materials used for the pump and high-performance servomotors provide short cycle times of 0.5 seconds for viscous products. Thanks to the special rotor-stator geometry, the dosage is virtually pulsation-free and low-shear. Maximum protection of the high-quality pharmaceutical products is guaranteed. By means of an adjustable retraction at the dosing end, a defined thread breakage is achieved and dripping is prevented.

Flexibility for the future

Thanks to the modularity of the dosing system, the filling dispenser is flexible enough to be quickly modified to respond to a wide range of customer requirements. These include e.g. changing formulations (from liquid suspensions to highly viscous ointments or pastes) or different volumes. Even abrasive and solid-laden media can be filled with low shear and in a process-safe manner. The ViscoTec dosing modules can be reprogrammed in the shortest possible time and can be put back into operation immediately.

Pharmaceutical compliant, hygienic design

The VPHD pharmaceutical dispenser is manufactured as standard with stainless steel wetted components in 1.4404 (AISI 316L), an electro-polished surface Ra ≤ 0.8μm and with inspection certificate 3.1 according to EN 10204. All non-metallic wetted parts are FDA compliant. In order to meet the high requirements for cleaning, the design allows for CIP / SIP cleaning. The dispenser can be disassembled without tools for manual cleaning.
