Downstream – NEMO® Water-Injection Pump:

Dissolves Crude Oil from Spongy Rock with High Pressure Stability



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
