Pumps play a key role in the production and manufacturing process of aircrafts, especially in the dosing of adhesives and sealants for bonding and compacting components. Various types of pumps are used for these jobs, including gear pumps and progressive cavity pumps. The latter are known for their high dosing accuracy, reliability, and durability. With high filler contents that are larger than the internal tolerance gap dimensions or with fillers such as glass beads, which are important for the structure production of the medium, gear pumps reach their limits and are therefore suitable only to a limited extent. Particularly in applications in aircraft and vehicle construction, high demands are placed on the adhesive or sealant to be used, as they are exposed to great stresses due to thermals and ambient temperatures. Due to their high resistance to abrasive and viscous media, progressive cavity pumps are ideal, as they dose particularly precisely and reliably. The pumps are self-sealing and do not require an additional metering shut-off valve to prevent dripping. This results in a clean application without material loss. Especially when it comes to sealing screws and rivets, gluing and compacting individual components, or filling edges, the user is offered advantages not only with regard to environmental protection, but also from an economic point of view.
