Principle
WINDRYEmbrace the engineering excellence of our Screw Vacuum Pump, meticulously designed with dual parallel screw rotors and a precision-crafted pump body. These elements form multiple sealed spaces, where the rotors and pump body maintain precise clearances, guaranteeing no contact and no friction. Driven by reverse gears, gas moves fluidly and consistently from the inlet to the outlet, delivering exceptional performance with every use.
Experience unparalleled efficiency with our frictionless dual rotor and pump body design, eliminating lubrication needs and ensuring pure gas delivery. Enjoy continuous, high-efficiency gas transfer through a streamlined pathway, while the strategically positioned outlet below the screw rotors enhances drainage and simplifies maintenance. Our design, free of intermediate bulkheads, outshines claw and rotor vacuum pumps in both drainage and exhaust efficiency, all while being remarkably easy to maintain.(Click on inquiry)
