Edson Electric Powered Diaphragm Pumps are the most popular of all Edson Pumps due to their size, capacity, versatility and the economy of electric drives. They are used for the collection and transfer of waste liquids and pumping liquids with suspended solids. They 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. These basic performance features & Edson’s 14 year history of manufacturing quality products have made our pumps the choice for cleaning up our environment and controlling the disposal of liquid waste. These pumps can be applied to a very broad range of applications including the requirements for ground water remediation, containment transfers, dewatering, oil & water separations, marina & campground sewage collection, tank, sump and drum transfers, filtration applications, and the collection & transfer of abrasives & slurries.
