Downstream – NEMO® Multiphase Pumps

The solution for low-pulsation delivery of media with high gas content

Very seldom does crude oil arrive at the surface in pure form; usually it is mixed with water, sand and gas. Conventional pumps require the gas first be separated from the crude oil, however, not with NETZSCH NEMO® Multiphase Pumps. NEMO® Multiphase Pumps can be used for crude oil with a gas content of up to 100%.

Features of NEMO® Multiphase Pumps:

  • handles substances with high gas content
  • low-pulsation handling
  • high suction capability

NEMO® Multiphase Pumps offer you:

  • low life cycle costs
  • low installation costs
  • high pressure stability
  • precision metering

Advantages of the NEMO® Multiphase Pump

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