Problem
In the valve used for filling ice cream with fruit pieces, O-rings were used to support and guide the piston, which quickly wore out and caused piston jamming. The developers were therefore looking for an alternative that was as lubrication-free and maintenance-free as it was durable.
Solution
The solution was found at igus. The O-rings were replaced by a new special seal and iglidur plain bearings, which serve as support and guide ring of the piston. Free of external lubricants, the bushings are suitable for the food industry and easy to replace. Wear went down to a minimum and there are no more piston jamming.
