How a Liquid Ring Vacuum Pump Works

Liquid ring vacuum pumps are remarkably simple in design. Due to their simplicity, they’re well suited for companies who need a vacuum system they can rely on to work and deliver uniform and satisfactory results. Liquid ring vacuum pumps contain several crucial parts, each of which works hand-in-hand to power your facility’s operations. They are the inlet port, sealing liquid, sealing liquid inlet, impeller cell, discharge port, and impeller.

  • The impeller contains several blades, and the shaft positions it off-center in a cylindrical housing.
  • The housing is then partially filled with the sealing liquid.
  • Next, the shaft rotates, which creates a powerful centrifugal force generated by the rotating impeller.
  • The force of the rotation holds the liquid ring to the inside wall of the pumping chamber, and because the impeller is not centered in the chamber, the depth of entry from the blades increases and decreases. The rising and falling action is what creates the vacuum.
  • Then, on the discharge port side of the machine, the impeller cell volume decreases as the blades dig more into the liquid ring.
  • The continuous flow of fresh sealing liquid moves to the pump through the discharge.
  • Finally, the first stage discharges through the manifold, which leads through a discharge port.

The Signs of Liquid Ring Vacuum Pump Failure

If you are experiencing problems with your liquid ring vacuum pump, then there’s no reason to delay. D & D Compressor, Inc. provides capable and speedy repairs to vacuum pumps of all sizes and pumps, regardless of the industry.

We use our experience and access to technology and parts to provide efficient repairs to the equipment you rely on most to do business. Fortunately, there are some signs indicating your liquid ring vacuum pump requires repairs:


There is an enormous amount of highly-pressurized liquid swirling around your vacuum pump. It continuously churns, raising the possibility that the chamber could become contaminated by the day. If you notice a decrease in efficiency or vacuum strength, then a contaminated pump could be at fault. We know how to diagnose this issue and how to restore to its optimum level.


Corroded parts are another common culprit of liquid ring vacuum pump failure. For instance, some liquids and gases can corrode the surfaces of your liquid ring vacuum pump. We can replace your broken pump and restore the overall system to good working order.
