Principle
WINDRYOur Screw Vacuum Pump is a marvel of precision engineering, featuring dual paralleled screw rotors and a pump body that together form a series of sealed chambers. This design ensures that the rotors and pump body maintain precise minimal clearances, achieving a frictionless operation. By utilizing reverse gears, the pump transports gas smoothly and continuously from the inlet to the outlet, delivering unmatched performance and reliability.
The frictionless synergy between the dual rotors and pump body negates the need for lubrication, ensuring the provision of pure, uncontaminated gas. The streamlined gas transfer mechanism, coupled with a sophisticated pathway, yields supreme efficiency. The innovative outlet design enhances drainage efficiency and simplifies maintenance, outshining traditional claw and rotor pumps with its superior exhaust and drainage capabilities.
