Progressive Cavity Dosing Systems

We recommend these metering systems for very abrasive and sensitive materials of low to medium viscosity with functional fillers: Eccentric screw pumps permit particularly gentle and low-pulsation feed; in addition, the output can be regulated depending on the speed, thus ensuring a constant material flow rate – meaning that pumps (including dispensers) based on eccentric screw technology are particularly suitable for special metering tasks.

Low maintenance

The use of eccentric screw technology is particularly suitable for high-wear applications, which can often help significantly reduce the relatively high service and maintenance requirements of such applications.

In the metering system shown here, for example, component A is fed from a 1000-litre IBC container. In this instance, the highly abrasive material is metered using an eccentric screw pump, while an agitator in the container prevents the filler from being deposited. Component B, on the other hand, is fed from a 200 litre drum and metered using a gear pump. Both of the components are finally blended using a disposable mixer made of plastic.

Systems made to meet your requirements

All of our pumps are designed exactly to meet the specific requirements of each application – a key prerequisite to ensure a maximum service life as well as optimum performance and reliability of a metering system. This is the approach we take in all of our client projects: no matter whether you need a bonding, sealing or casting solution, we always design our mixing and dispensing systems according to your specific requirements. The same goes for feeding technologies: materials can be fed from IBC containers, drums or pressure vessels, and we can fit them with a heating system if required.
