Principle
WINDRYOur state-of-the-art Screw Vacuum Pump is meticulously engineered with dual paralleled screw rotors enveloped by a precision-crafted pump body, forming multiple hermetically sealed chambers. These components are designed with exceptionally tight clearances to prevent contact and friction. Driven by reverse gears, this sophisticated mechanism allows gas to flow smoothly and consistently from the inlet to the outlet, guaranteeing unparalleled performance.
Thanks to its innovative frictionless design, the dual rotors and pump body function without lubrication, delivering contaminant-free gas. The seamless gas transfer, combined with an optimized flow path, ensures exceptional efficiency. The outlet's strategic positioning below the screw rotors enhances drainage capability and simplifies maintenance. Absent of an intermediate bulkhead, our design significantly outperforms traditional claw and rotor vacuum pumps in drainage and exhaust efficiency, while being remarkably user-friendly.
