Roots-Liquid Ring Vacuum Systems

The Roots-liquid ring vacuum system is composed of a liquid ring pump as the backing pump and a Roots pump as the main pump in a series configuration. The liquid ring pump is used to initially evacuate the vacuum system and then the Roots pump further enhances vacuum level, with both working synergistically for efficient gas extraction. Volm offers a wide range of multi-stage vacuum systems, providing complete engineering solutions that cover instrumentation, condensers, control devices, piping and valves, and partial or full working fluid circulation systems, offering users one-stop service.

Product Features

Strong Adaptability

Capable of extracting not only ordinary gases but also gases containing moisture, organic solvents, or small amounts of crystalline substances. Resistant to oil contamination, water vapor, and fine dust, making it suitable for various complex operating conditions

Various Working Fluids

Water, oil, or process fluids can serve as working fluids. When using oil as working fluid, it prevents corrosion and avoids fluid vaporization at elevated temperatures. When using process liquids, it prevents contamination of process gases by water or oil

Exceptional Vacuum Performance

Delivers high vacuum levels and high pumping speeds at high vacuum, meeting the process requirements that demand stringent vacuum conditions

Structural and Operational Advantages

Simple design ensures long-term reliable operation. Integrated skid design for plug-and-play use, saving time and costs

Energy-Saving & Eco-Friendly

High pumping speeds at high vacuum ensure energy efficiency. The system can be equipped with closed circulation systems to reduce wastewater discharge, compliant with environmental protection requirements
