Dry Screw Vacuum Pump 

Composed of counter-rotating screws, pump body, end cover, sealing components, etc., the structure is very simple

Independently produced and manufactured, with over 40 patent technologies, rated as a high-tech enterprise and a science and technology enterprise, and has passed ISO9001 quality management system certification

Dry operation, no need for any working medium, thus no oil pollution, no wastewater discharge, and significant energy-saving effect

Core components are processed by imported processing equipment from Japan, with precision up to 0.001mm

There is a certain gap between the screw and the pump body

Nickel-phosphorus alloy, Hastelloy alloy, Teflon

A single screw dry vacuum pump can replace a three-stage Roots pump water ring vacuum unit

Can be combined with Roots pumps to form a vacuum system, achieving higher ultimate vacuum degree and increasing pumping speed

generally around 80 decibels

Dry operation, easier to recover solvents

Suitable for extracting condensable gases (such as water vapor) and dusty gases

From the atmosphere to the ultimate pressure of 5 Pa, one pump can solve the problem
