Typically, vacuum priming systems are manufactured in either simplex or duplex configurations, using either rotary vane or liquid ring vacuum pump technology. The determination of which system is best for each project is dependent upon application specifics as well as the goals and preferences of the owner. For example, what is more important? The lowest power consumption or the lowest maintenance? Low initial cost or the protection of redundancy? Using your input, Q-VAC engineers will select the best system for your application.
