Flux Drum Emptying Systems VISCOFLUX lite

The drum emptying system VISCOFLUX lite is used to transfer higher-viscosity media which are just capable of flowing out of ISO drums with lid. In the Ex version it is suitable for the use in hazardous areas of zone 1 and for transferring a wide variety of flammable media (zone 0/1). The system transports the media gently and continuously.
Like the VISCOFLUX and the VISCOFLUX mobile, the VISCOFLUX lite leaves just less than 1 % of the media in the drum.

The components of the VISCOFLUX lite drum emptying system are the FLUX eccentric worm-drive pump with motor,
the pump centring plate and the follower plate with process seal. The follower plate is put directly onto the media in the drum. The pump centring plate is fixed above it on the edge of the drum. The pump is then routed through the opening of the pump centring plate and the follower plate guide down to the bottom of the drum. The eccentric worm-drive pump creates a vacuum, so the follower plate goes down.

The flexible process seal of the follower plate makes sure that almost no material remains on the drum wall. The material transferred is hermetically sealed in. In this way, the VISCOFLUX lite empties drums to less than 1 % residue. After the transfer of the medium, the follower plate is released from the bottom of the drum by means of compressed air.


  • Transfers higher-viscosity substances that are just capable of flowing
  • The flexible process seal makes sure almost no material remains on the drum wall
  • Residue in the drum less than 1 %
  • Mobile for easy transport to the drum
  • Eccentric worm-drive pump for gentle transport of the medium with little turbulence and pulsation
  • Combination of pump and motor can be individually adapted to the medium to be transported (modular system)


  • Resource-saving – up to less than 1 % residue
  • Efficient use of the medium and low expenditure for disposal
  • Continuous and gentle transport, no structural change of the medium
  • Customized solution due to individual selection of drive motor in combination with suitable eccentric worm-drive pump
  • Fast cleaning as system can be quickly dismantled
  • Process reliability due to hermetical sealing of the medium even if the transfer process is interrupted
  • High flexibility due to low installation height – also suitable for working rooms with relatively low ceilings
  • Simple extension due to comprehensive range of accessories (flow meters, hoses, fittings etc.)
  • Quick to install with few components


  • Substances just capable of flowing
  • Soft lubricating greases up to NLGI class 2 (e. g. machinery greases)
  • Leveling compounds
  • Base materials for paints and varnishes
  • Solvent-based blend pastes
  • Coating compounds (base coats)


  • Delivery rate: max. 50 l/min
  • Delivery pressure: max. 8 bar
  • Viscosity: up to max. 500.000 mPas
  • Transfers higher-viscosity substances that are just capable of flowing
  • Designed for ISO: lidded drums with an inner diameter of 571.5 mm
  • Residue in the drum: less than 1 %
  • For eccentric worm-drive pumps with outer diameter: 54 mm
