The Delavan 7802-201 PowerFLO Electric Diaphragm Pump (Automatic Demand) uses a combination of valves on each side of the diaphragm as well as the reciprocating action of a Santoprene diaphragm to move the liquid. This particular product could be suitable for industrial, commercial or agricultural uses. Because the diaphragm itself is made of Santoprene, it has a higher resistance to corrosion.

**The fittings for the pump inlet and outlet are sold separately. If you are unsure of what you need please contact a customer service representative for assistance.**
