Product Description

Introducing our exceptional range of China Factory Manufactured Screw Compressor Vacuum Pumps, expertly designed for those who demand efficiency and reliability. These oil-lubricated pumps, integrated with Permanent Magnet Inverter technology, operate within a pressure range of 0.8-1.0Mpa. They are perfectly suited for an array of industries such as Electronics, Carbon Fiber, Brick, Ceramics, Foam, Injection Molding, Blister, Vacuum Packaging, and Vacuum Handling. Offering a versatile power capacity from 10HP to 100HP, our pumps ensure optimal performance for diverse applications.



Working Principle

The Screw Vacuum Pump operates with a sophisticated mechanism utilizing a pair of precision-engineered screws that rotate synchronously at high speed in opposite directions within the pump casing. This dynamic interaction creates a powerful suction and exhaust function. The screws, carefully balanced and supported by robust bearings, maintain a specific clearance to ensure frictionless operation, resulting in an impressively smooth and quiet performance. Capable of handling substantial volumes of water vapor and small amounts of dust-containing gas, this pump excels in delivering superior vacuum limits, reduced power consumption, and energy-saving benefits. Its maintenance-free design makes it an ideal choice for sectors such as pharmaceuticals, chemicals, semiconductors, and food packaging, where a pristine vacuum environment is paramount.
