Precision Vacuum System:

Our Liquid Ring Vacuum Pumps are engineered for the most demanding industrial applications, offering a robust and reliable solution for handling gas and vapor. By utilizing a rotating liquid ring—typically water—as the piston, these pumps provide a frictionless compression process. This unique design ensures consistent performance even in harsh environments where dust, small particles, or condensable vapors are present.

Key Benefits

• 
  High Durability & Reliability

  With only one moving part (the rotor) and no metal-to-metal contact, wear is minimized, significantly extending the service life and reducing maintenance costs.

• 
  Cool & Safe Operation

  The liquid ring acts as a heat sink, ensuring near-isothermal compression. This makes it an ideal choice for handling heat-sensitive or explosive gases.

• 
  Contaminant Tolerance

  Capable of processing gas streams containing soft solids, moisture, and aggressive chemicals without damaging the internal components.

• 
  Low Noise & Vibration

  Precision balancing and the absence of reciprocating parts ensure quiet operation, improving the workplace environment.

NEWSCO liquid ring vacuum pumps operate on the liquid ring principle to generate stable vacuum performance and effectively handle water vapor, condensable gases, and a variety of process gases. With a simple design and high operational reliability, they are widely used in chemical, petrochemical, power generation, pulp and paper, food, pharmaceutical, and other industrial applications.

The rotating impeller forms a liquid ring that performs compression and discharge. This non-contact compression design minimizes internal friction, vibration, and noise, providing stable performance during long-term continuous operation. It also ensures reliable operation in processes involving moisture-laden gases or condensable vapors.

Depending on process characteristics, various seal liquid system configurations can be applied, including Total Loss, Partial Recovery, and Once-Through systems. SVC provides optimized system configurations tailored to operating conditions and customer requirements, helping reduce seal liquid consumption and improve operating efficiency.

A wide range of material options, including Stainless Steel and Duplex Stainless Steel, as well as various shaft seal arrangements, are available for corrosive or high-humidity process conditions. Depending on project requirements, the pump can also be supplied as a complete package system incorporating a heat exchanger, gas separator, seal liquid tank, and other auxiliary equipment, improving installation convenience and ease of maintenance.

With a robust design and excellent durability, NEWSCO liquid ring vacuum pumps minimize maintenance requirements while delivering reliable operation and strong lifecycle value in industrial processes requiring long-term continuous duty.
