These are small and lightweight vacuum pumps, MINI, with large capacity that can compensate for leakages. The MINI pumps are available with different characteristics, accessories and designs so that they can be adapted to different applications. The Chip pump can be mounted onto various types of bottom plates and, through this, be given numerous connection possibilities. It can also be fitted with valves and/or a vacuum sensor. By doing so, a complete system (Mini System) is created, and such a system can, when necessary, be dimensioned for larger flows.
