Principle
WINDRYOur Screw Vacuum Pump is a testament to engineering excellence, crafted with precision using dual paralleled screw rotors and a uniquely designed pump body, forming multiple sealed spaces. The synergy between the rotors and pump body, with their precise clearances, assures no contact or friction. Driven by reverse gears, gas seamlessly flows from inlet to outlet, delivering unparalleled performance.
Thanks to its frictionless architecture, the dual rotors and pump body operate without lubrication, ensuring the delivery of immaculate, clean gas. The strategic gas flow, with a streamlined pathway, assures high efficiency. The outlet's strategic positioning below the screw rotors not only boosts drainage but also simplifies cleaning. By eliminating an intermediate bulkhead, our design outshines claw and rotor vacuum pumps in both drainage and exhaust efficiency, while maintenance remains a breeze.
