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
In wear- and corrosion-resistant designs.
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.
