Downstream – NEMO® Multiphase Pump:

The Solution for Low-Pulsation Delivery of Media with High Gas Content

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 percent.

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

Technique

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 Block construction
The drive is flanged directly to the lantern of the pump, resulting in compact dimensions, low total weight, constant axial heights irrespective of the construction type and size of the drive, and ease of maintenance and serviceability as well as high efficiency.

The NETZSCH NEMO® transfer pump is available in …

  • cast iron
  • chrome-nickel-steels
  • duplex and super-duplex steels
  • Hastelloy
  • titanium
  • plastics and ceramic materials
  • special materials

TORNADO® T2 Industrial Rotary Lobe Pumps

The TORNADO® T2 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® Water-Injection Pump

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.

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.
