Liquid ring pumps and compressors utilize rotating positive displacement technology and are typically used in liquid ring vacuum pump applications, but can also be used as a gas, or liquid ring compressor. These sturdy pumps are built for heavy duty, wet and humid applications where most other pumps' performance will drop due to abrasion and lime scale from the process. The larger liquid ring pumps are often part of engineered systems designed to meet even the highest demands.
This is how they work: the impeller rotates friction free within the pump casing. A rotating liquid ring seals the impeller on the front and seals its blades against one another. In order to keep the liquid ring stable, liquid is also permanently sucked into the compression chamber and is output together with the conveyed gas. The excentrical arrangement of the impeller within the casing creates variable compression chambers between the impeller blades during rotation, which causes the conveyed gas to be compressed within a full revolution.
