Liquid Ring Vacuum Pumps and Systems

Liquid ring vacuum pumps are available in a wide range of metallurgies and sealing options to suit specific applications, including use in hazardous flammable and explosive areas. Their versatility and reliability means they are widely used in facilities of all sizes and across many industries.

Available as single- or two-stage liquid ring units, these pumps can handle high volumes of vapours, condensable gases and liquids without compromising performance or mechanical reliability. The service liquid – water or other liquids, oils or solvents – can be selected to suit almost any application. When clean water is used, the aspirated air is ‘washed’ free of contaminants such as oil, carbon or plastics.

Liquid ring vacuum pumps are designed for simplicity and reliability. Fewer components simplifies maintenance, while minimal moving parts eliminate metal-to-metal contact, significantly reducing vibration, noise and wear.

Key features:

• Duties up to 3500 m3/h
• Max vacuum: 33mbar
• Single or double mechanical seal (DIN 24960 standard)
• Designed and manufactured to ISO 9001 standards
• Close-coupled and long-coupled options with open impeller
• Can handle gases and vapours
• Fewer components for improved rigidity and easier maintenance
• Compact dimensions with reduced shaft length minimising deflection and vibration
• Simple design with no valves or sliding vanes
• Impeller is the only rotating part – no metal-to-metal contact, reducing wear and tear
• ATEX certification available on request

Materials of construction:

• Cast iron, AISI 316, Ni-Resist D2B, Hastelloy B, Hastelloy C, Uranus B6 and exotic alloys.
