Principle
WINDRYBehold the engineering marvel of our Screw Vacuum Pump, meticulously crafted with dual paralleled screw rotors and an intricately designed pump body, forming multiple sealed chambers. The precision engineering of the rotors and pump body ensures minimal clearances, resulting in zero contact and friction. Propelled by reverse gears, gas is effortlessly and continuously directed from the inlet to the outlet, affirming unparalleled efficiency.
Our frictionless design, featuring dual rotors and a seamless pump body, negates the necessity for lubrication, facilitating the delivery of pristine gas. The unceasing gas transfer coupled with an optimized pathway guarantees superior efficiency. Strategically positioned lower than the screw rotors, the outlet amplifies drainage capability and streamlines cleaning processes. The absence of an intermediate bulkhead elevates our design above claw and rotor vacuum pumps in drainage and exhaust efficiency, while maintaining effortless upkeep.(Click to contact inquiry)
