Dry-compressing pumps that excel in vacuum casting
This company’s product portfolio includes a range of dry-compressing and oil-sealed pumps tailored to the foundry industry. Vacuum plays a crucial role in casting, preventing air entrapment and enabling the production of thin-walled light-weighting castings parts. These dry-compressing vacuum pumps have an oil-free compression mechanism that, in a casting machine, significantly reduces the maintenance and operating costs of the vacuum system. The pumps have screw rotors that rotate frictionlessly in the compression chamber, resulting in low energy consumption. Dry-compressing vacuum pumps also help with dust management. In dry pumps, small particles are simply transported to the exhaust, causing no wear, as they do in oil-lubricated pumps. — Leybold GmbH, Cologne, Germany
