Pumps Explosion–Proof Drum Emptying
The drum emptying system Viscoflux lite for high-viscosity media is now available as an Ex version. The new explosion-proof variant is suitable for use in hazard areas of zone 1 as well as for pumping most flammable media (zone 0/1).
Contrary to the standard version of Viscoflux lite, the individual components of the Ex version (Ex-marking II 1 G IIB TX), pump centring plate and follower plate including process seal as well as the compressed-air hose are made of conductive or static dissipative materials. Comprehensive and precise potential equalization can be carried out over suitable connections for earthing wires. The system is quick to install, requires little space and due to its low build can also be used in working spaces with low ceilings.
To continuously and gently transport higher-viscosity materials which are just capable of flowing, Flux engineers use eccentric worm-drive pumps. In combination with a follower plate, a vacuum is created during pumping causing the plate to lower. In doing so the process seal of the follower plate hermetically seals the remaining material thus preventing unwanted emissions and changes to the product. Even if the pumping operation should be interrupted, a maximum degree of process reliability is guaranteed. Finally, almost no material remains on the wall of the drum, allowing for almost complete emptying.
