Principle
WINDRYOur Screw Vacuum Pump exemplifies engineering brilliance, featuring dual parallel screw rotors and an expertly crafted pump body that together form multiple sealed compartments. These components are precision-engineered to maintain minimal clearances, ensuring they operate without contact or friction. Utilizing reverse gears, the pump transfers gas efficiently and continuously from the inlet to the outlet, guaranteeing optimal performance.
Thanks to its innovative frictionless design, the dual rotors and pump body operate without lubrication, delivering uncontaminated gas. The continuous gas transfer and streamlined passage contribute to its superior efficiency. The outlet is strategically positioned lower than the screw rotors, enhancing drainage and simplifying maintenance. With no intermediate bulkhead, our design offers unparalleled efficiency in drainage and exhaust compared to claw and rotor vacuum pumps, and it's remarkably easy to maintain.(Click to contact inquiry)
