Principle
WINDRYOur Screw Vacuum Pump is an engineering marvel, meticulously designed with dual paralleled screw rotors and a precisely crafted pump body. This configuration creates multiple sealed spaces while the rotors and pump body maintain minute clearances, ensuring no contact and no friction. Driven by reverse gears, gas flows seamlessly and continuously from the inlet to the outlet, delivering exceptional performance and reliability.
Boasting a frictionless design, the dual rotors and pump body negate the need for lubrication, ensuring the supply of uncontaminated gas. The continuous gas transfer, coupled with a streamlined pathway, results in unmatched efficiency. The strategically lower outlet enhances drainage and simplifies cleaning. With no intermediate bulkhead, our design outshines traditional claw and rotor vacuum pumps in both drainage and exhaust efficiency, making maintenance unexpectedly simple.
