The Delavan PowerFlo 12V FatBoy Series 3 Diaphragm Pumps have a new and improved design that results in extended pump life and improved performance for many of your professional spraying applications.

The improved design of the Delavan FB 3 Diaphragm Pumps result in longer pump life and a much more efficient operation compared to previous 7 gpm (26.5 lpm) diaphragm pumps. They provide a more consistent operation over a wide pressure range, providing the consumer with a reliable pump that produces less amp draw and less heat, meaning greater performance over the long haul.

The Delavan FB3 Diaphragm Pumps have chemically-resistant Viton valves that are excellent for pumping a variety of general use agricultural chemicals for lawn and turf spraying, including herbicides, pesticides, liquid fertilizers, insecticides, and more. Other uses include roof cleaning with mild chemicals, dust suppression, and more.

Bypass Pumps are used in applications where a wide range of flows and pressures are required (eg. spray bar with multiple nozzles, each controlled independently). The pump will continue to run regardless of pressure in the system. The flow rate is different if one nozzle is turned on opposed to turning two or more nozzles on. As nozzles are turned off, excess flow is bypassed within the pump.

Note: The motor surface temperature should not surpass 180°F (82.22℃)
