Liquid Ring Compressors

The units are primarily used in wastewater treatment, biogas (digester gas) compression, and aeration systems. They are also suitable for other industrial processes requiring reliable low-pressure gas compression.

• Technical Parameters
  The maximum discharge pressure reaches up to 30 PSIG (3 bar(g)). The blowers are designed for low-pressure operation within this range. Water is used as the standard operating (sealing) liquid; in case of process incompatibility, an alternative operating liquid may be applied depending on the medium.
• Design and Materials
  The blowers are available in stainless steel, ductile iron, or other materials depending on gas chemical compatibility and specific application requirements.
• Operating Principle and Performance Characteristics
  The liquid ring principle operates without direct metal-to-metal contact between the rotor and the compressor casing. This design concept ensures stable compression characteristics and reduces mechanical wear.
• Configuration Flexibility
  Selected NASH vacuum pumps can also be configured as low- or medium-pressure blowers, enabling integration into process lines while maintaining equipment design continuity.
