Downstream – NEMO® Water-Injection Pump

Dissolves crude oil from spongy rock with high pressure stability

The NEMO® water-injection pump can be used for conveying pressures up to 240 bar, regardless of the properties of the fluid. The construction materials make operation with either smearing or non-smearing products equally unproblematic.

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

1 Rotor
In wear- and corrosion-resistant designs.

2 Stator
Vulcanized into the tube with sealing on both sides in a variety of elastomers, plastics and metals. Stator inlet with hopper-shaped opening for improved feed of the product into the conveying chamber. The stator is oil-, acid- and alkali-resistant.

3 Drive chain
Coupling rod and two gimbal joints for the transmission of power from the drive to the rotor.

4 Shaft seals
Standard with single-acting, bi-directional, wear-resistant mechanical seal. Upon request, with single- or double-acting mechanical seals of varied designs and from various manufacturers, cartridge and special seals as well as packed glands.

5 Suction and discharge housing
Flange and threaded connections in accordance with DIN and international standards. Materials in cast iron, steel, chrome-nickel-steel rubberized; also special materials upon request.

6 Bearing block with free shaft extension
Large double bearing ensures a high level of shaft stability and thereby ideal conditions for a great variety of mechanical seals. The free shaft extension makes it possible to use any drive type including diesel and hydraulic drives.

TORNADO® T.Envi® Rotary Lobe Pump

The TORNADO® T.Envi® rotary lobe pumps in FSIP® design are optimally adapted to your requirements in environmental and biogas technology and impress with easy maintenance.

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%.

NEMO® BT Immersible Pump With Hanging Bracket or Dome Cover Flange

NEMO® Immersible Pumps are used for emptying barrels, tanks, and pits. They are also used where space is limited and the danger of cavitation may be present. In addition, these pumps are suitable for emptying barrels containing materials hazardous to water and the environment.

NEMO® Progressing Cavity Pump in FSIP® Design

The FSIP® concept of the NEMO® progressing cavity pump is especially interesting where pumps are installed in wear intensive applications.
