Pneumatic pump for transferring lubrication and oil. Designed and developed for use in particular application fields, it has been created with the use of the most suitable materials to guarantee high performance and resistance.
Pneumatic pump is particularly suitable for the dispensing of medium viscosity oil for short and medium distances. It can be installed on drums and connected to a dispensing solution consisting of several service stations, equipped with reels and dispensing nozzles. It is therefore used in all workshops that need a high-performance oil transfer system that is durable and reliable over time.
