In this application, vacuum pumps are used to maintain a siphon in power plant cooling water systems. Maintaining a siphon allows cooling water circulating pumps to maintain design cooling water flows with minimum power consumption. Single stage liquid ring pump packages, often supplied with specially designed NASH priming valves, are ideal for this application because they prevent ingesting of water slugs into the pumps.
