Dry Vacuum Pumps Use Fewer Resources

Going to the dentist was always fun for me as a child. The dental hygienist and I had the same first name. I thought that was pretty special. Sitting on the motorized reclining chair and slowly leaning back was pretty cool. My favorite part of the whole experience was the suction tube. Closing my mouth around the tube and allowing the suction effect to suck the saliva out of my mouth. I liked the sound of it. This suction effect is driven by a dry vacuum pump.

Dry vacuum pumps, also known as oil less vacuum pumps, use fewer resources, such as water and electricity, than other types of vacuum pumps. This lowers water and sewer and electricity costs. Dry vacuum pump systems use no water, eliminating installation and annual inspections of reduced prevention pressure zone back flow. For the aforementioned reasons, dry vacuum pumps are ideal for medical and dental use.

Many dry vacuum pumps use a series of rotating vanes that are attached to a stationary barrel. The vanes are not fixed and are able to “float” at precise angles. Originally, the vanes were made out of carbon and were designed to be self-lubricating with dry carbon dust. Improvements in design and technology, however, have changed some elements. Carbon materials have been replaced by better composite material because carbon can be delicate and may not be able to tolerate problems such as foreign object ingestion, continued reverse rotation or lack of proper maintenance.

Measured by their pumping speed and throughput, dry vacuum pumps are used in a multitude of manufacturing applications. Their pumping speed, also known as their volume flow rate, is multiplied by the gas pressure at the inlet of the pump. Dry vacuum pumps are used in the petrochemical, food manufacturing and medical applications. The pumps are used for drying, distilling, degassing, freezing, evaporating, suction and laboratory analysis.
