Principle
WINDRYOur Screw Vacuum Pump is a marvel of engineering excellence, showcasing dual paralleled screw rotors and a meticulously crafted pump body that form multiple sealed spaces. The sophisticated design ensures minute clearances between rotors and pump body, guaranteeing no contact and zero friction. Powered by reverse gears, it provides seamless, continuous gas transfer from inlet to outlet, delivering outstanding, superior performance.
With its frictionless architecture, the dual rotors and pump body eliminate lubrication needs, ensuring the provision of clean, untainted gas. This continuous gas transfer, coupled with an optimized flow path, ensures exceptional efficiency. The strategically positioned outlet below the screw rotors enhances drainage and simplifies cleaning processes. Without an intermediate bulkhead, our design surpasses conventional claw and rotor vacuum pumps in both drainage and exhaust efficiency, while offering remarkable ease of maintenance.
