Product Description

Discover the exceptional prowess of our China Factory manufactured Screw Compressor Vacuum Pumps. These oil-lubricated marvels, featuring a cutting-edge Permanent Magnet Inverter, operate within the impressive range of 0.8-1.0Mpa. Ideal for a broad spectrum of industries, including electronics, carbon fiber production, brick and ceramics manufacturing, foam processing, injection molding, blistering, vacuum packaging, and vacuum handling. With a power spectrum ranging from 10HP to 100HP, our pumps are designed to meet diverse industrial needs with unmatched efficiency.



Working Principle

The screw vacuum pump operates on a sophisticated mechanism involving a pair of high-precision screws. These screws revolve synchronously at high speeds in opposite directions within the pump casing, creating an effective suction and exhaust system. This dynamic balance is achieved through meticulous corrections and robust bearing support, ensuring the screws maintain an optimal clearance without friction, resulting in seamless operations with minimal noise. This advanced design efficiently removes substantial amounts of water vapor and minor dust-laden gases while offering superior vacuum levels, reduced power consumption, and energy-saving benefits. Notably, our pumps are maintenance-free and cater to industries demanding pristine vacuum environments, such as pharmaceuticals, chemicals, semiconductors, and food packaging.
