Simplex Water Sealed Liquid Ring Priming Systems

Q-VAC simplex priming systems with water-sealed liquid ring vacuum pumps are a great choice for priming applications that require lower cost, the lowest possible maintenance, and long-term durability.  This robust vacuum pump technology has been used successfully for both clean water and wastewater applications, however, it is especially well suited for wastewater projects or outdoor installations in warmer climates.  Standard sizes are offered up to 15 HP, but significantly larger sizes are available.   Water sealed liquid ring vacuum pumps are rated up to 29” HgV, although they are typically operated at lower vacuum levels to prevent cavitation.  Electromechanical controls are standard.  PLC controls are available.

In order to consider a water-sealed liquid ring priming system, you must be able to supply a suitable water source and drain for when the vacuum pump is running.  If a continuous supply of seal water is not available, but liquid ring technology is still preferred, Q-VAC offers closed-loop, air-cooled, liquid ring priming systems using either water or oil as the seal fluid.
