Kowell PVOVAC P3000 dry screw vacuum pump maintenance completed.

The scorching summer days couldn’t slow down Aisituo’s team as they pressed forward on their "vacuum" journey. Today’s star player is quite the heavyweight—a single pump with a total capacity of 1.5 tons: the original, South Korean-imported KEWOLL P3000 dry screw vacuum pump, capable of an impressive actual pumping speed of 2,700 cubic meters per hour. This large-scale dry screw vacuum pump can achieve an ultimate vacuum level of around 13 Pa when running solo—making it one of the bigger players in the screw vacuum pump family.

What are the advantages of small screw vacuum pumps compared to oil-sealed rotary vane vacuum pumps?

A screw vacuum pump operates by creating a sealed space between two parallel screw rotors and the pump housing, maintaining a precise rotational clearance between the rotors themselves and between the rotors and the housing—ensuring zero friction. Driven by reverse-synchronized gears, this design allows gas to be continuously drawn in through the inlet and expelled through the outlet, generating a vacuum. Because there’s no friction between the rotors and the pump housing, the pump chamber remains clean and requires no lubrication. As a result, screw vacuum pumps are ideally suited for handling large amounts of water vapor, solvents, and even small particles of dust, making them perfect for applications like gas and solvent recovery processes. Unlike multi-stage claw or multi-stage Roots vacuum pumps—which feature intermediate partitions—screw vacuum pumps offer continuous operation with short gas pathways, delivering high efficiency, easy cleaning, and minimal risk of clogging.
