Safe operation and no need for maintenance - both were major design criteria during the development of DIGIDOS. The combination of brass and stainless steel guarantees ruggedness and durability throughout the firefighting truck's service life.

A gear pump is used as foam compound pump. This pump type does not have inlet or outlet valves and is equipped with stainless-steel gears. The choice of material and the lack of valves guarantee unrivaled operating safety for extinguishing operations.

Thanks to direct coupling of the gear pump and the drive motor - without a clutch or gear box - the whole unit is completely maintenance-free!

• No maintenance of the proportioner
• No sticking valves or similar problems
• Extremely rugged pump type
