Flux drum emptying system for transferring high-viscosity fluids
German pump technology firm Flux-Geräte is now offering customers a solution for transferring high-viscosity materials from special sea container drums.
The follower plate and process seal of the Viscoflux mobile drum emptying system is designed for opening diameters of lidded drums with 560mm and 571mm as standard.
During the fluid transfer process the process seal adapts to beadings and slight dents. The wall of the drum is stripped so that it is almost entirely residue-free, meaning that residual quantities of less than 1% (less than 2% for drums with aseptic bags) can be achieved.
In contrast to ISO lidded drums, special sea container drums have a single drum rim that tapers slightly, resulting in a smaller opening diameter. The challenge lies in configuring the follower plate and process seal so that they can reach into the narrow drum opening without exerting great pressure.
On the other hand, they must bear enough tension to allow for the drum wall to be stripped properly. This has been achieved by reducing the size of the follower plate, whilst at the same time marginally strengthening the process seal. The Viscoflux mobile can achieve the same results with drums suitable for containers as with a standard ISO lidded drum.
