INTRODUCTION TO WATER 
RING VACUUM PUMPS
Definition:
•  A Water Ring Vacuum Pump, also known as 
a liquid ring vacuum pump, is a type of positive 
displacement pump used to create vacuum in 
various industrial applications.
Purpose:
•  These pumps are essential for processes 
requiring consistent vacuum performance,

especially in moist or saturated environments.
PRINCIPLE OF OPERATION
   Positive Displacement Mechanism
• Main Components:
a. Impeller (rotating blades)
b. Casing (housing the impeller)
c. Sealing Liquid (typically water)
• Working Process:
a. Impeller rotates eccentrically within the casing.
b. Centrifugal force forms a liquid ring.
c. Eccentric motion creates expanding and contracting 
chambers.
d. Gas is drawn in through the inlet, compressed, and expelled 
via the discharge port. https://tmvt.com/
KEY COMPONENTS 
OF A WATER RING 
VACUUM PUMP
• Impeller: Creates the motion needed for 
suction and compression.
• Casing: Encloses the system and maintains 
liquid ring pressure.
• Sealing Liquid: Absorbs heat and allows for 
gas compression.
• Inlet/Discharge Ports: Direct gas flow during 
the pumping cycle.

ADVANTAGE • Handles Wet and Saturated 
S OF WATER Gases: Ideal for moisture-heavy 
RING environments.
• Isothermal Compression:

Minimal temperature rise during 
PUMPS compression.
• Durable with Low 
Maintenance: Only one moving 
part—impeller.
• Safe Operation: No metal-to-
metal contact; safe in hazardous 
atmospheres.
