Principle
WINDRYOur Screw Vacuum Pump is expertly engineered with dual paralleled screw rotors housed within a precision-crafted pump body, forming multiple sealed chambers. These rotors, in perfect harmony with the pump body, are skillfully designed to maintain precise clearances—ensuring no contact and zero friction. Powered by reverse gears, this ingenious design facilitates the seamless and continuous transfer of gas from the inlet to the outlet, guaranteeing unmatched performance.
Boasting a frictionless design, the dual rotors and pump body eliminate the need for any lubrication, delivering consistently clean gas. Our streamlined gas transfer pathway enhances overall efficiency, with the outlet positioned strategically lower than the screw rotors to maximize drainage capability and simplify cleaning processes. The absence of an intermediate bulkhead allows our design to significantly surpass traditional claw and rotor vacuum pumps in both drainage and exhaust efficiency. Maintenance is effortlessly simple.(Click on inquiry)
