Principle
WINDRYOur Screw Vacuum Pump is expertly engineered with dual paralleled screw rotors and a precision-crafted pump body, forming numerous sealed spaces. The rotors and pump body are designed to maintain ultra-fine clearances, ensuring no contact and no friction. Driven by reverse gears, gas flows effortlessly and continuously from the inlet to the outlet, delivering exceptional performance.
Thanks to its frictionless architecture, the dual rotors and pump body do not require lubrication, guaranteeing the delivery of uncontaminated gas. The continuous gas transfer, along with a streamlined pathway, leads to outstanding efficiency. The outlet, positioned lower than the screw rotors, enhances drainage and simplifies cleaning. With no intermediate bulkhead, our design exceeds that of claw and rotor vacuum pumps in both drainage and exhaust efficiency, while being remarkably easy to maintain.(Click to contact inquiry)
