Learn About Liquid Ring Technology

Elmo Rietschle’s L-Series pumps utilize advanced liquid ring technology to deliver efficient and reliable performance in wet and abrasive environments.

The operating principle involves an eccentrically mounted impeller rotating within the pump casing, forming a liquid ring that seals the impeller blades. As gas enters through the suction port, it is trapped in blade cells and compressed as the impeller rotates. The liquid ring enables simultaneous vacuum and compression operations, making these pumps versatile and efficient for diverse applications.

Key features of the L-Series include:

Ceramic Coating: Prevents lime scaling and ensures steady performance.

Maximum Abrasion Resistance: Withstands harsh conditions for long-term durability.

Superior Corrosion Resistance: Ideal for environments with aggressive media.

Monobloc Design: Prevents deposits and metal contact for maintenance-free operation.

Enhanced Water Carryover Tolerance: Adds versatility across industrial processes.

How do Liquid Ring Pumps Work?

Elmo Rietschle’s L-Series liquid ring pumps utilize a simple yet innovative operating principle to deliver reliable performance in wet and abrasive environments.

 

  1. Formation of the Liquid RingAn eccentrically mounted impeller rotates within the pump casing, creating a liquid ring that seals the impeller blades. This liquid ring is key to maintaining consistent vacuum and compression performance.
  2. Gas CompressionAs gas enters through the suction port, it is trapped in blade cells and compressed as the impeller rotates. This compression generates a pressure difference, allowing the pump to function as both a vacuum pump and a compressor.
  3. Liquid StabilizationLiquid is continuously drawn into the compression chamber to stabilize the liquid ring. This process ensures smooth and reliable operation, even in demanding industrial applications.
  4. Expelled Liquid and RecirculationThe liquid, along with the conveyed gas, is expelled from the pump. For enhanced efficiency, the expelled liquid can be recirculated using standardized circuit units, reducing water usage and operational costs.
  5. Condensation and VersatilityThe ability to condense vapor within the conveyed gas adds versatility to the liquid ring pump design, enabling it to replace gas washers, filters, coolers, and exchangers in certain applications.

This innovative mechanism ensures stable and energy-efficient operation with minimal liquid supply, making Elmo Rietschle’s L-Series liquid ring pumps a top choice for industries that require reliable vacuum and compression in wet and challenging environments.
