Principle
WINDRYOur Screw Vacuum Pump is a masterpiece of engineering, featuring dual paralleled screw rotors that perform in harmony within a precision-crafted pump body. This design forms multiple sealed chambers, with meticulously calculated clearances that ensure no contact or friction occurs. These elements work in concert, driven by reverse gears, to transfer gas efficiently from inlet to outlet, granting you unparalleled performance with every use.
Thanks to its innovative frictionless design, our pump's dual rotors and pump body function without lubrication, ensuring the delivery of pristine gas. The streamlined gas transfer process, combined with an optimized pathway, delivers outstanding efficiency. Our unique outlet positioning, strategically lower than the screw rotors, maximizes drainage and simplifies cleaning. This design, devoid of any intermediate bulkhead, surpasses traditional claw and rotor pumps, offering superior drainage and exhaust capabilities, all while being remarkably easy to maintain.(Click on inquiry)
