Principle
WINDRYOur Screw Vacuum Pump embodies precision excellence, featuring dual paralleled screw rotors and a meticulously engineered pump body that creates multiple sealed spaces. The rotors and pump body are crafted with exacting clearances, ensuring no contact or friction. Driven by reverse gears, gas is transferred seamlessly and continuously from inlet to outlet, guaranteeing exceptional performance.
Our frictionless design eliminates the necessity for lubrication, providing clean gas delivery. The continuous gas transfer, combined with a streamlined pathway, results in remarkable efficiency. The outlet, strategically positioned lower than the screw rotors, enhances drainage capability and simplifies cleaning. Without an intermediate bulkhead, our design surpasses claw and rotor vacuum pumps in both drainage and exhaust efficiency, offering ease of maintenance.(Click to contact inquiry)
