What is a vacuum
A vacuum priming
system is an industrial vacuum system designed specifically for priming
centrifugal water pumps. Major components include vacuum pumps, air receivers,
priming valves, and control panels. Priming systems are typically
manufactured as simplex or duplex designs using rotary vane or liquid ring
vacuum pumps. Fully automatic controls are typically used, however on-demand
systems with manual controls are available. A well designed priming system
will ensure safe, long term performance and ease of maintenance.
Where are Priming Systems used?
Since introduction of the Q-VAC brand in the early 1990ís, Q-VAC
Automatic Priming Systems have been installed in power plants, municipal water
systems and wastewater treatment plants, industrial applications, irrigation
systems, steel mills, marine applications, siphon control systems, water box
priming, and other centrifugal pump priming applications.
Why do you need a priming system?
centrifugal pump can operate, it must first be primed; that is, air or gases
must be expelled from the suction and impeller area, and replaced with liquid.
This is not a problem when the pump is submerged (i.e. submersible or vertical
sump pumps) or when the liquid supply is above the pump. However, when suction
pressure is negative, air must be evacuated to accomplish pump priming.
