Introduction

The CHINAMFG dry compound screw vacuum pump is the latest innovation in vacuum pump technology. It uses the fifth-generation of compound variable pitch screw technology, which allows it to save up to 30% in energy and produces low exhaust temperatures. It is characterized by its high efficiency, energy-saving properties, environmental friendliness, lightweight design, easy operation, and reliable performance, making it the future of vacuum pumps.

The air-cooled design is 100% oil-free and features a self-designed multistage flat seal that can withstand strong resistance to water vapor. The screw rotors use the latest in variable pitch screw technology and have no contact with each other. The pump uses a mechanical flat seal for easy maintenance and has a maximum vacuum reach of 1Pa.

Working Principle

The dry compound screw vacuum pump consists of two parallel screw rotors and a pump body that form multiple sealed spaces. The rotors and pump body all have minuscule clearance, which means no touch and no friction. With reverse gear driving, gas continuously transfers from the inlet hole to the outlet hole. Due to the rotors and pump body not having friction, there is no need for lubricating oil, and the gas remains clean. The gas continuously transfers, with short passageways, high efficiency, and easy to clean. The outlet hole position is lower than the screw rotors and has strong drainage ability, better exhaust, and drainage, with no intermediate bulkhead.
