Downstream – NEMO® Water-Injection Pump

NEMO® Water-Injection Pumps ensure that your oil is flowing in the right direction!

General

Crude oil deposits are often discovered in spongy rock. To extract it, fluids must be pumped into the earth under high pressures. NEMO® Water-Injection Pumps are particularly well-suited for this task, since their capacity can be changed in accordance with rotation speed.

Features of NEMO® Water-Injection Pumps:

  • high pressure stability
  • low-pulsation conveyance
  • high suction capability

NEMO® Water-Injection Pumps offer you:

  • low life cycle costs
  • low installation costs
  • high efficiency

Advantages of the NEMO® Water-Injection Pump

  • can be operated under high conveying pressures
  • capable of pumping a great variety of substances
  • capacities are adjustable

TORNADO® Industrial Rotary Lobe Pumps T2

The TORNADO® rotary lobe pump is a positive displacement pump. The pumping action is generated by the contra-rotation of two rotors within the pump chamber which are synchronised externally. The media enters the pump chamber through the inlet port and is carried around the chamber by the rotors to the outlet port where it is discharged.

Downstream – NEMO® Multiphase Pumps

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%.
