Introducing the ZJQ series air-cooled Roots vacuum pumps, an innovation stemming from the esteemed ZJ series. Enhanced with a sophisticated bypass gas cooling system, these pumps are meticulously engineered to prevent overheating even under significant pressure disparities. The ingenious design incorporates heat exchangers at the exhaust outlet, ensuring the expelled gas is efficiently cooled before re-entering the pump chamber to maintain optimal rotor and chamber temperature. Notably, this innovative cooling technique enhances operational efficiency without compromising pump performance. The ZJQ series can function independently or in a series configuration, seamlessly integrating with liquid ring, reciprocating, and slide valve vacuum pumps. This adaptability delivers exceptional vacuum levels and unprecedented pumping speeds to satisfy rigorous industrial requirements, all while offering extraordinary energy savings.
· Operates independently with a working vacuum capacity directly exhausting to the atmosphere, achieving a robust vacuum range of 15-20 kPa.
· Seamlessly integrates with a front pump, forming a high-efficiency Roots series unit. By varying configurations,5 ~10-2 Pa can be achieved, delivering remarkable energy conservation.
· The unique design ensures no friction among moving parts, eliminating the need for lubrication. Enjoy a pristine vacuum environment free from oil contamination within the pump chamber.
· Our precise three-leaf clover structure and high-precision machining guarantee seamless, quiet operation.
· Experience significant advancements in air extraction performance, noise reduction, and vibration control compared to traditional dual-blade rotor pumps.
· Vertical gas flow within the pump chamber aids effective removal of dust and condensate, ensuring clean, efficient operation.
· Boasts a broad application spectrum, excelling even under increased inlet pressures.
· Motor power varies; maximum operational pressure differences must be calculated per process conditions to precisely determine required motor power.
