The KLS series oil-free screw vacuum pumps are dry vacuum pumps with advanced technologies independently developed by our company. Since the screw vacuum pumps do not require oil lubrication or water sealing, and the pump cavity is completely oil-free, they have incomparable advantages over traditional water ring vacuum pumps, rotary vane vacuum pumps, slide valve vacuum pumps, reciprocating vacuum pumps, and water jet vacuum pumps. They not only save energy and reduce emissions but also are low-carbon and environmentally friendly, representing a new development trend in the vacuum industry. They are suitable for a variety of applications such as packaging, papermaking, CNC, plastics, glass, leather, foam, printing and dyeing, PVC pipes, bottle making, wood processing, and meat product packaging.
