Dry screw vacuum pumps are highly efficient, oil-free pumping systems designed to handle a wide range of industrial applications. These pumps operate using two synchronized, non-contacting screw rotors that rotate in opposite directions to create vacuum without the need for lubrication in the pumping chamber. Their robust and contamination-free design ensures reliable performance, minimal maintenance, and superior handling of corrosive, toxic, or condensable gases.
Models: KDP150, KDP330, KDP400, KDP800
The KDP Screw-Type Dry Vacuum Pump is specifically engineered to handle process by-products such as liquids, condensates, and small particles. Its robust and simple design ensures reliable operation in demanding industrial applications without contamination from oil or water.
Versatile Handling: Capable of managing liquids, condensates, and small particles without performance degradation.
Oil-Free and Water-Free Operation: No oil or water comes into contact with the process, ensuring a clean and contamination-free environment.
Non-Contacting Design: No contact between operating components within the casing, reducing wear and maintenance requirements.
High Pumping Speed:
Full pumping speed from atmospheric pressure down to 1 Torr.
Ultimate pressure as low as 0.1 Torr (0.05 Torr for Model KDP-800).
Quiet Operation: Produces less than 85 dB(A) during operation, promoting a quieter working environment.
Efficient Gas Discharge: Short gas path through the pump ensures quick discharge and minimal process interruption.
Flexible Drive Options: Extended shaft design allows for V-belt or direct drive configurations.
Durable Construction: Casing and rotors are constructed from ductile iron and coated with PFA for enhanced durability and chemical resistance.
