NETZSCH Barrel Emptying Pumps:

Automatically and Almost Residue-Free Emptying of Barrels and Containers

General

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. This then simultaneously puts slight pressure on the substance in order to guarantee constant suction in the pump.

Features of NEMO® barrel emptying pumps:

  • Nearly shear-free conveyance of highly viscous, highly abrasive or highly filled substances
  • Continuous or intermittent emptying
  • Clean emptying, residue of less than one to two percent
  • No hiatus
  • Very gentle, low-pulsation conveyance
  • Very little pressure on the follower plate
  • Emptying of conical barrels
  • Low pressure conditions in the system
  • Capacity is infinitely adjustable by means of the rotation of the motor
  • Dosing directly from the barrel

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

Applications

Applications

NEMO® barrel emptying pumps are universally applicable and empty nearly any container. They have a wide spectrum of applications and are used primarily for substances with the following properties:

  • Low to high viscosity
  • Dilatant, thixotropic or structurally viscous
  • Highly filled
  • Shear-sensitive and pressure-sensitive
  • Highly abrasive
  • Smearing or non-smearing
  • Sticky or gel-like
  • Heated or unheated

…such as RTV silicones, 1K and 2K epoxies, PUR sealing compounds, petroleum jelly, various fats, fruit concentrates and doughs.
