Model 638 Lever Action Bottom Inlet Pumps are ideal for installations where the pump must be directly above the liquid to be transferred, such as on the top of a barrel, tank or floor openings. Material enters through the bottom of the pump and discharges to the side. The pumps use a 32" handle to drive the diaphragm with an easy back and forth lever-action motion. Size 30 Pump - Aluminum - 2" Inlet & Discharge - Nitrile Diaphragm & Valves.
