Working Principle
Discover the innovative design of the Screw Vacuum Pump, expertly crafted by Sanzhi (Henan) Compressor Co., Ltd. This advanced device utilizes a pair of screws rotating synchronously in high-speed reverse motion within the pump casing to achieve exceptional suction and exhaust capabilities. Precision-balanced and supported by robust bearings, these screws are meticulously mounted to minimize clearance, ensuring frictionless operation. This results in smooth performance, significantly reduced noise levels, and the ability to handle substantial amounts of water vapor and minor dust-laden gases. Features include superior vacuum limits, reduced power consumption, energy efficiency, and maintenance-free operation. Ideal for industries such as pharmaceuticals, chemicals, semiconductors, and food packaging, this vacuum pump meets the stringent demands for pristine vacuum conditions.
