Principle
WINDRYDiscover unparalleled craftsmanship in our Screw Vacuum Pump, featuring dual paralleled screw rotors and a precision-engineered pump body. The creation of sealed spaces, achieved through minute clearances, ensures no contact and no friction. Driven by reverse gears, it facilitates seamless gas transfer from inlet to outlet, delivering impeccable performance.
With an innovative frictionless design, our dual rotors and pump body operate without the need for lubrication, ensuring the purity of gas delivery. The continuous transfer of gas, coupled with an efficient pathway, maximizes efficiency. The outlet, strategically positioned below the screw rotors, enhances drainage and simplifies maintenance. Lacking an intermediate bulkhead, our design offers superior drainage and exhaust efficiency compared to claw and rotor vacuum pumps, with remarkable ease of maintenance.
