NEMO® Immersible Pumps – special design for the petroleum industry

Dependable conveyance with no overflow

In the oil field, surface water mixed with crude oil accumulates in pits. These pits must be emptied. There can be considerable variation in the viscosity of this oil/water mixture, depending upon its temperature and the ratio of its components. NETZSCH® Immersible Pumps convey this mixture reliably and securely to processing plants from depths of up to 15m.

Wide Spectrum of Applications
The NEMO® Immersible Pump is used primarily for substances with the following properties…

  • low to high viscosity (1 mPas to 100,000 mPas)
  • thixotropic and dilatant
  • shear-sensitive
  • abrasive
  • non-smearing or smearing
  • aggressive (pH 0 to 14)
  • adhesive
  • toxic

… such as

  • crude oil
  • crude oil polluted with water and sand
  • oil/water emulsions
  • water in oil deposits
  • oil sludge

Additional Features of the NEMO® BT Immersible Pump:

  • suction pipe extension can be mounted to lengthen immersed tube
  • lowest possible NPSH
  • bi-directional
  • low noise, low vibration
  • temperatures from -40°C to 160°C
