Principle
WINDRYExperience unparalleled engineering with our Screw Vacuum Pump. Crafted with precision, dual paralleled screw rotors, and an expertly designed pump body create multiple sealed spaces. The intricate design ensures no contact or friction as rotors and pump body maintain minute clearances. Through reverse gear-driven mechanics, gas is effortlessly transferred from inlet to outlet, offering peak performance and reliability.
With an innovative frictionless design, our dual rotors and pump body eliminate lubrication needs, delivering clean gas efficiency. Coupled with a streamlined pathway, continuous gas transfer is achieved effortlessly. An optimally positioned outlet enhances drainage and simplifies cleaning, while surpassing claw and rotor vacuum pumps in efficiency and maintenance ease.
