Edson diaphragm pumps are primarily designed for the collection and transfer of waste liquids and pumping liquids with suspended solids. All of the diaphragm pumps are capable of handling liquids with large suspended solids without clogging, to prime from dry starts, and to run dry. They have the added feature of low emulsive, non-sheering pumping action.
