Dry

Dry pumps have no lubrication in the gas stream. Any chemical lubricants are isolated from the gas stream by seals which prevent back streaming of lubricants that may occur with “wet” pumps. Dry pumps are the pump of choice in applications where back streaming of oil is a big concern. Dry pumps can be designed for scroll, compressing piston, compressing screw, or diaphragm type pumps.
