Simplex or Duplex?

Determining whether your application requires a Simplex or Duplex Priming System relates to the importance of the process, performance requirements, and operational demands.  Please contact us for assistance.     

Advantages of Simplex and Duplex
Vacuum Priming Systems

 Simplex Primers   Duplex Primers 
 Lower initial cost  100% redundant
 Simplified controls  Advanced controls
 Maximum efficiency
 Longer maintenance intervals

Simplex Systems Maintain Prime Automatically
Our QVS series simplex priming systems provide the basic performance and automatic controls needed to prime your pumps at the lowest cost and space requirements. Although these systems do not include all the advantages of our duplex priming systems, they are still designed and built by Q-VAC with features and quality unmatched in the industry.

Standard Simplex Models: 
Simplex Rotary Vane Vacuum Priming Systems
Simplex Liquid Ring Vacuum Priming Systems

Duplex Systems Offer Increased Reliability, Efficiency and Longevity
Our QVD series duplex priming systems provide advanced controls and the security of built-in redundancy.  Since two vacuum pumps operate during initial priming, smaller vacuum pumps can be selected without sacrificing performance. However, to maximize efficiency after initial priming, only one vacuum pump runs during normal operation. Not only does this reduce power consumption and operating costs, it also reduces the run time on each vacuum pump to extend maintenance intervals and maximize life.

Q-VAC duplex priming systems include our standard PLC controller and vacuum transducer to provide unsurpassed system control and reliability. Other standard control panel features include an illuminated LCD display, HMI touchpad, LED indicator lights, alarm horn, and dry alarm contacts. Programming features include automatic alternation, lead-lag control, frequent start protection, hour meters, system operation status, and alarms. Q-VAC duplex priming systems have everything necessary for long life and reliability.

Standard Duplex Models:
Duplex Liquid Ring Vacuum Priming Systems
Duplex Rotary Vane Vacuum Priming Systems

In addition to our standard models, larger Simplex and Duplex Priming Systems are available and special options may be offered.

We offer the best value in quality automatic vacuum priming systems for centrifugal water pump priming, siphon control systems, and water box primers.  Q-VAC Priming Systems are ideal for power plants, municipal water systems and wastewater treatment plants, industrial applications, irrigation systems, steel mills, and marine applications.  Please contact us for expert assistance in selecting the best solution for your application.
