Delavan 3120-421F SmartFLO 12-Volt Bypass/Demand Diaphragm Pump - Bypass+Demand

Description

Combine the advantages of both a bypass pump and a demand pump all in one with this Delavan 3120-421F SmartFLO 12-Volt Bypass/Demand Diaphragm Pump.
An ideal upgrade for your spraying unit, this 12-volt diaphragm pump features innovative SmartFLO technology that combines the advantages of both bypass and demand pump styles so you are better suited to handle varying flow rates and a wider variety of applications. The pump heads have both an internal bypass valve and a pressure sensing demand switch, allowing your system to adapt to changing demands to deliver consistent flow rates, regardless of which discharge ports are open. Once all the system outlets are closed, the pressure sensing demand switch activates to turn the pump off. These bypass / demand pumps provide consistent flow on demand, while eliminating pump cycling with any outlet system configuration.
This Delavan 3120-421F SmartFLO Bypass/Demand Pump can be used in marine and RV applications, fluid transfer applications, agricultural spraying, spot spraying, lawn / turf spraying, and many other applications.
