NEMO® Barrel Emptying Pumps

We’ll get the very last of it out for you!


NEMO® Barrel Emptying Pumps suction themselves automatically to the bottom of the barrel or container to achieve almost residue-free emptying in the chemical, pharmaceutical and foods industries. The heart of the Barrel Emptying System is a volumetrically conveying NEMO® Progressing Cavity Pump.

When the NEMO® Pump is started, a vacuum is created under the follower plate. The vacuum simultaneously puts slight pressure on the substance that guarantees constant suction in the pump.

Features of NEMO® Barrel Emptying Pumps:

  • very gentle conveyance
  • nearly residual-free emptying
  • conveyance of compacted products
  • conveyance of solids

NEMO® Barrel Emptying Pumps offer you:

  • conveyance volume in proportion to rotation speed
  • constant low-pulsation conveyance
  • high efficiency
  • low life cycle costs combined with easy serviceability
