Our industrial open systems feature a lubricated rotary vane pump, one of the simplest and most reliable pump types available. The use of oil in the pump produces higher efficiencies, lower operating temperatures, and lower sound levels. These pumps are also the most suitable to high ambient temperatures, which makes them ideal for manufacturing or process applications where environmental temperatures tend to be higher. (Consult factory for applications where ambient temperatures are above 104°F.) These pumps also have the lowest initial cost and high ultimate vacuum levels (29.3″ Hg end vacuum). By creating a modular frame mounted system with a centralized ASME air receiver and adding a UL listed NEMA 1 control panel, Powerex has designed systems that are perfect for manufacturing processes like material handling, packing, food processing, and printing.
