Leybold’s new Dryvac DV 500 and DV 800 screw vacuum pumps compress completely dry, without operating lubricant in the compression chamber, making them suitable as backing pumps in food packaging or pumping sets in heat treatment or coating systems, They reportedly have significant advantages over oil-lubricated piston or rotary vane vacuum pumps.
Due to a screw design with a specially adapted variable pitch, the pumps work extremely efficiently, consume less power and require minimal maintenance compared to oil-lubricated vacuum pumps. The robust screw vacuum pumps are also characterized by high particle and condensate compatibility.
DV 800's dimensions are directly derived from proven DV 650 models, making changeover and integration easier for the user. The DV 800 opens up new possibilities for applications where a higher pumping speed is required.
The Dryvac DV 500 and DV 800 are equipped with an easily adaptable and networkable frequency converter and IE3 motors. Monitoring via a cloud platform can also be easily implemented on request and is available as standard from Q3. The compact and well thought out construction of the DRYVACs enables a Roots vacuum pump RUVAC to be easily installed as a booster.
