Principle
WINDRYOur Screw Vacuum Pump is a marvel of engineering, featuring dual paralleled screw rotors intertwined with a precisely crafted pump body. This creates multiple sealed chambers, with rotors and pump body designed to maintain tiny clearances—no contact, no friction. Driven by reverse gears, the gas is seamlessly and continuously transferred from inlet to outlet, delivering unparalleled performance.
Thanks to its frictionless architecture, the dual rotors and pump body operate without lubrication, ensuring clean gas delivery. The continuous gas transfer combined with an optimized pathway promises high efficiency. Positioned below the screw rotors, the outlet enhances drainage capability and simplifies cleaning. The absence of an intermediate bulkhead allows our design to surpass claw and rotor vacuum pumps in both drainage and exhaust efficiency, all while being incredibly easy to maintain.(Click to contact inquiry)
