Principle
WINDRYOur Screw Vacuum Pump is ingeniously designed with dual paralleled screw rotors and an expertly crafted pump body, resulting in multiple sealed spaces. These components are engineered for impeccable precision, maintaining minute clearances with no contact or friction. The reverse gear-driven mechanism enables continuous and seamless gas transfer from the inlet to the outlet, delivering unparalleled performance.
Thanks to its innovative frictionless design, our dual rotors and pump body operate without lubrication, ensuring the output of clean gas. The continuous transfer of gas, coupled with a streamlined pathway, guarantees exceptional efficiency. The outlet is strategically positioned lower than the screw rotors to boost drainage capabilities and ease cleaning processes. Without any intermediate bulkhead, our design outshines claw and rotor vacuum pumps in drainage and exhaust efficiency and is remarkably easy to maintain.
