3/4 Inch Hollow Shaft

<p style="text-align: justify;"> The EF4000 Everflo 12 Volt Diaphragm Pump is ideal for fluid transfer applications, agricultural sprayers, spot sprayers, and is even rated for Round-Up. </p> <p style="text-align: justify;"> This lightweight and versatile Everflo diaphragm pump comes equipped with a polypropylene pump housing and valve plate, viton valves and a santoprene diaphragm. This Pump also features a flow demand switch that automatically turns the pump on and off as flow is required. This feature eliminates the need for a pressure regulator or by-pass valve also making this a very efficient electrical draw pump, as power is only used when the pump flow is in demand. </p> <p style="text-align: justify;"> Please remember that Demand Pumps require a balanced flow. Too small of a nozzle (whether on your Spray Gun or on your Spray Boom) may restrict the flow resulting in your Demand Pump repeatedly shutting off and on. </p> <p style="text-align: justify;"> We recommend using the AA122-1/2-PP Poly Line Strainer to help eliminate contaminates from running through your Everflo Pump. Please see the Related Products tab to view the Everflo pump in different flow rates. </p>
