Viscous and heavy substances are a major challenge for pump dispensers. The resistance of viscous substances results in hollow cavities in the contents while pumping, and the performance suddenly breaks down. Therefore, Joma relies on the vacuum pump system. Placed directly on top of the content, the follower plate prevents unwanted air intake and transports fluid and even highly viscous substances uniformly through the dip tube. It fits snuggly against the container walls and hygienically protects the content from drying out.
