Working Principle & Technology

Understanding the liquid ring technology where liquid acts as a piston to create reliable vacuum performance with high capacity throughput

Liquid Ring Technology

Liquid Ring Vacuum Technology

The liquid ring vacuum pump operates on the principle where liquid acts as a piston. A balanced rotor with fixed radial blades revolves eccentrically in a casing containing liquid, creating compression and vacuum cycles through the varying liquid ring distance.

1

Liquid Ring Formation

Liquid rotates in casing forming circular hollow ring at varying distances from rotor axis

2

Suction Stroke

Moving liquid ring acts as piston on suction stroke when nearest to rotor axis

3

Compression & Discharge

Chamber volume decreases as liquid ring moves toward center, compressing and discharging gas
