Rotary lobe pumps are currently often used in hygienic and aseptic filling processes. Using the GEMÜ F60 servoDrive filling valve, developed by Ingelfingen-based valve specialist GEMÜ, not only allows these filling processes to be made significantly faster and more flexible, it also extends service lives.

The GEMÜ servoDrive actuator design excels through its high traverse speed, excellent positioning accuracy and fast controllability. The low-loss, brushless and robust servo motors made from stainless steel satisfy the requirements of electrical protection class IP69K and can achieve 50 to 100 million cycle duties, depending on the application.

An accuracy test was performed with the GEMÜ F60 servoDrive for filling with the smallest quantities. The aim here was to achieve the accuracy required when filling pharmaceuticals of ±0.5% at a filling weight of 1 g. The test was performed with water and a continuous pressure of 0.3 bar. The results showed that the requisite accuracy was delivered over multiple measurement series. Further tests with various small volumes also confirmed the filling accuracy. A filling cycle time of significantly less than one second could be achieved with all fill volumes. The GEMÜ F60 servoDrive allows faster filling cycles than the rotary lobe pumps that are currently often used. In addition, various filling volumes can be implemented without having to modify the filling plunger. Alongside filling of pharmaceutical products, the GEMÜ F60 servoDrive is also suitable for all filling applications that require accuracy, speed and hygiene, such as foodstuffs or battery and chemical filling.
