125 to 7000 psi Compressors Water Cooled (6000 Series)
The water-cooled compressors of the SAUER 6000 series have a modular design with up to six cylinders, which allows many different variations with final pressures of up to 7,000 psi and a drive power of up to 308 hp. As the largest immersion piston compressors of their kind, they allow maximum performance even in the most difficult conditions.
Outstanding characteristics:
- High flexibility in compression unit configuration
- Low-vibration operation through special W- or V-arrangement of compression units
- Highly integrated and fully operational unit for foundation-free installation
- Anti-vibration mounts for structure borne noise isolation
- Integrated cooling water circuit with high performance water coolers for each cylinder
- Extensive protection systems with temperature and pressure sensors available in each stage
- Compression of several technical gases possible due to gastight crankcase and low leakage rates
- Variable frequency drive possible with defined speeds – optimization of every process
Every compressors comes with:
- Long operating life with guaranteed spare parts availability (at least 25 years) from stock

- Operating Pressure: 125 – 7000 psi
- Flow Rate: 160 – 470 SCFM
- Required Power: 105 to 275 hp
- Stages/Cylinders: 3/6, 4/6, 5/6
- Gas/Medium: Air, Nitrogen, Helium, Natural Gas, Bio-Methane
Features
Magnetic coupling
The wear-free magnetic coupling drive between compressors and motor not only guarantees hermetical gas-tightness but also is extremely low-maintenance and operates with maximum reliability.
Integrated water cooling
The most efficient cooling solution for high drive power, reliable and easy to maintain.
Hermetically gas-tight design available
The reliable, hermetically gas-tight compressor design ensures that neither gas can escape nor ambient air can contaminate the compression medium.
