Lincoln now offers its upgraded Model 85634 and Model 85635 Air-operated, UL-listed Diaphragm Pumps. A result of Lincoln's continuous effort to provide superior pump technology, the pumps deliver higher flow rates and greater solids handling capability.

Each pump features the no-lube air valve and grounding wire and a one-inch inlet and outlet. The two models have aluminum construction with a choice of Buna or PolyTetraFluoroEthylene (PTFE) wetted soft parts.
