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