Principle
WINDRYOur Screw Vacuum Pump is a marvel of precision, crafted with dual paralleled screw rotors coupled with a meticulously designed pump body. This innovation creates multiple sealed spaces, with rotors and pump body engineered for impeccable minute clearances-guaranteeing no contact and frictionless operation. Through reverse gear propulsion, it ensures a seamless, continuous transfer of gas from inlet to outlet, delivering superior and unparalleled performance.
Thanks to its frictionless architecture, the dual rotors and pump body obviate the need for lubrication, ensuring unblemished clean gas delivery. With a continuous gas transfer through a streamlined pathway, it achieves remarkable efficiency. The strategically positioned outlet, lower than the screw rotors, augments drainage capability and simplifies cleaning. Our superior design, free from intermediate bulkheads, outshines claw and rotor vacuum pumps in drainage and exhaust efficiency, with effortless maintenance.
