Principle
WINDRYOur Screw Vacuum Pump is a marvel of engineering, featuring dual paralleled screw rotors and a precisely crafted pump body. Designed with painstaking attention to detail, these components create multiple sealed spaces. The rotors and pump body are meticulously crafted to maintain minute clearances, ensuring no contact and no friction. Driven by reverse gears, this design guarantees seamless and continuous gas transfer from the inlet to the outlet, providing unparalleled efficiency and performance.
Boasting a frictionless design, the dual rotors and pump body negate the need for lubrication, delivering consistently clean gas output. The continuous transfer mechanism, combined with a streamlined pathway, ensures maximum efficiency. Our uniquely positioned outlet, lower than the screw rotors, significantly boosts drainage capacity and simplifies the cleaning process. The absence of an intermediate bulkhead allows our design to outperform claw and rotor vacuum pumps in terms of drainage and exhaust efficiency, all while being incredibly easy to maintain.
