This Two Stage Liquid Ring Vacuum Pumps have the below features:

  • Able to pump every kind of gases and vapours
  • Able to handle small quantities of liquid with gases
  • Oil-free, no need to lubrication
  • Pumped gas do not touch the oil
  • Minimum maintenance with high efficiency
  • No metallic contact of the rotating parts
  • Works quiet and reduced vibration
  • Nearly everywhere used with suitable material choices
     

Service Liquid
During pump working, service liquid must be supplied to replenish the liquid ring and to cool the pump (generally water is used). The exhausted liquid could be used again after separating the gas inside of It. The direction of the rotation is clockwise, when looking from the motor on the pump.

Vacuum Pumps
Versatile Gas Handling
Known for their exceptional versatility, these vacuum pumps stand out for their ability to handle a diverse array of gases and vapors. Their capacity to manage various gas compositions ensures adaptability across multiple industrial settings. These vacuum pumps are well-equipped to handle a diverse range of gases, making them a reliable choice for industries with varied operational needs.
Factory
Liquid Ring Vacuum Pumps offer pressure of up to 33 mbar absolute, which ensures a powerful suction capacity, capable of meeting the demands of numerous applications across different industrial sectors.
Oil Refineries
Engineered to operate quietly and with minimal vibration levels. This design makes them an ideal choice for settings where noise reduction and minimal vibration are essential.
pumps industry vacuum
Oil-free, no need for lubrication. This feature can reduce maintenance requirements and potential risks associated with oil-based systems, making the pump more efficient and potentially extending its operational lifespan.
