Product Description

Introducing the China Factory Manufacturer Screw Compressor Vacuum Pumps - the epitome of precision engineering, equipped with oil-lubricated, permanent magnet inverters. Whether your needs span electronics, carbon fiber, brick, ceramics, foam, injection molding, blister, vacuum packaging, or vacuum handling, our range from 10HP to 100HP promises unparalleled efficiency. Operating at a pressure range of 0.8-1.0Mpa, this energy-efficient marvel is designed to elevate your industrial processes.



Working Principle

The screw vacuum pump operates through the ingenious use of a pair of screws that rotate in synchronous, high-speed reverse motion within the pump casing, creating a powerful suction and exhaust mechanism. These meticulously synchronized screws, enhanced by precise dynamic balance corrections and supported by robust bearings, ensure seamless performance. Encased within the pump, the screws maintain a specific clearance, guaranteeing frictionless operation, minimal noise, and the ability to handle large volumes of water vapor and gas with minor dust particles. This advanced technology reaches an exceptional vacuum limit while maintaining lower power consumption, offering significant energy savings and maintenance-free benefits. Its superior vacuum capabilities, alongside its cost-effective energy usage, make it an ideal choice for industries with stringent clean vacuum requirements, such as pharmaceuticals, chemicals, semiconductors, and food packaging.
