Liquid ring vacuum pump systems & centralized units

The liquid ring vacuum system is ideal for your applications where medium to low vacuum is required, typically up to 33 mbar. Whether the process medium contains liquid droplets or solid inclusions, the liquid ring vacuum pump can handle these inclusions well. Since there is no metal-to-metal contact between the casing and the impeller and the gaps are large, the maintenance cost of such vacuum pumps is low. The liquid in the ring pump can be recycled.

What is the structure of liquid ring vacuum systems?

The core of the system is one or more liquid ring vacuum pumps. It also contains the auxiliary equipment and devices required to integrate the system into the process, such as a separator, heat exchanger, liquid circulation ring pump, etc. Our vacuum systems are available with PLC control and VFD.

What is the principle of operation of liquid ring vacuum systems?

  • Liquid ring vacuum pumps use water or other ring fluid compatible with the produced gas. An impeller rotates in the pump, which is eccentrically positioned in the casing. The pump is partially filled with annular fluid. Due to the rotation of the impeller and the resulting centrifugal force, the liquid in the casing forms a liquid ring. The pumped medium enters the space between the impellers and the liquid ring. Due to the eccentric position of the impeller, the volume between the blades varies with the angular position. During the suction phase, the volume increases, a vacuum is created and gas is drawn in. During the compression phase, the volume decreases, the gas is compressed and exits through the outlet.
  • During operation, liquid is constantly flowing out of the pump. A mixture of gas, vapour and liquid droplets exits the pump through the outlet. In the case of a disposable system, the liquid goes directly into the drainage system without polluting or wasting water. ASCO Vacuum is committed to environmentally friendly solutions, which is why we recommend closed-circuit systems.
  • In a closed-circuit system, droplets are drawn from the stream into a separator tank, from where the pump recirculates the ring fluid while cooling it through a heat exchanger.
  • The stable operation of the pumping system requires monitoring of the liquid level, vacuum and temperature, so our systems also include the necessary sensors and controls.
  • With a PLC, you can create a reliable and highly efficient vacuum system.
Flow Range: from 50 m3/h up
Vacuum: down to 33 mbar

Progressive cavity pumps

Today, ASCO POMPE manufactures screw pumps that are used in a variety of industries, from wastewater treatment plants to the wine and food industry. Screw pumps are positive displacement pumps and are designed for pumping various types of liquids: viscous, abrasive, additive liquids, suspensions and dispersions. The valve-less design of the pump, the direct dependence of its performance on the engine speed, and the ability to change the direction of flow of the pumped liquid are undoubtedly the advantages of screw pumps.
