The LG Series Dry Oil-Free Screw Vacuum Pump operates using a pair of precisely engineered parallel screws that rotate synchronously but in opposite directions. This mechanism creates a sequence of sealed chambers, which continuously transport gas for both suction and exhaust processes. Thanks to its advanced engineering, the pump eliminates the need for lubrication within the working chamber, delivering clean, oil-free vacuum performance that safeguards both your process media and the environment.
Designed with a unique screw structure, the pump achieves high pumping efficiency alongside an impressive capacity to discharge liquids. Its short and unobstructed pump cavity allows for smooth and efficient exhaust flow. Additionally, the rotor has undergone dynamic balance correction to enhance its operation, while premium bearings contribute to stable performance with minimal vibration and low noise levels.
Moreover, the pump incorporates corrosion-resistant components within its flow passages and features an automatic purging system. These characteristics enable it to effectively handle condensable gases, water vapor, and mildly corrosive substances. As a result, this pump is particularly well-suited for applications such as oil and gas recovery, solvent recovery, and the management of special gases.
