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