Principle
WINDRYOur Screw Vacuum Pump exemplifies engineering excellence, featuring dual paralleled screw rotors and a precision-engineered pump body. This design creates multiple sealed spaces with exacting clearances, ensuring no contact and no friction. The reverse gear-driven mechanism facilitates seamless, continuous gas transfer from inlet to outlet, delivering unparalleled performance.
The frictionless synergy of the dual rotors and the pump body negates the need for lubrication, guaranteeing the delivery of pristine gas. This, combined with a streamlined pathway, yields exceptional efficiency. Featuring an outlet strategically positioned below the screw rotors, our pump boasts enhanced drainage and simplified cleaning. Its design, lacking any intermediate bulkhead, surpasses claw and rotor vacuum pumps in drainage and exhaust efficiency, offering unparalleled ease of maintenance.(Click on inquiry)
