Downstream – NEMO® Multiphase Pumps

Even if the oil sometimes stops coming – NEMO® Multiphase Pumps keep going.


Only very seldom does crude oil arrive at the surface in pure form. Usually it is mixed with water, sand and gas. Conventional pumps require that the gas first be separated from the crude oil. With NETZSCH NEMO® Multiphase Pumps, this is not an issue.
NEMO® Multiphase Pumps can be used for crude oil with a gas content of up to 100%.

Features of NEMO® Multiphase Pumps:

  • employable even if the pumped substance has a high gas content
  • low-pulsation conveyance
  • high suction capability

NEMO® Multiphase Pumps offer you:

  • low life cycle costs
  • low installation costs
  • high pressure stability
  • perfect dosing precision

Advantages of the NEMO® Multiphase Pump

  • can be operated under high conveying pressures
  • can be used even if the oil has a high water content
  • dependable operation even with high-viscosity oils
  • employable for substances with a high solid content
