Bundle includes 2 Items: (1) Delavan 7871-111E PowerFlo FatBoy 3 Bypass Diaphragm Pump with (1) Male 1/2" Hose Barb Kit. The Delavan 7871-111E PowerFlo Diaphragm Pump is part of the new FatBoy 3 Series, which are designed with improvements to extend pump life and enhance performance. Compared to other 7 gpm electric diaphragm pumps, the Delavan 7871-111E offers a more efficient operation over a wide pressure range that results in less amp draw and less heat. Available with a bypass mode to suit the demands of professionals in the agriculture, lawn and turf, and roof cleaning industries. Bypass pumps are ideal for applications that require a wide range of flows and pressures (eg. spray boom with multiple nozzles, each controlled separately). The pump continues to run regardless of pressure in the system. The flow rate is different when one nozzle is turned on compared to having two or more turned on. Once nozzles are turned off, excess flow is bypassed within the pump. Use this Delavan FB3 series diaphragm pump on agricultural sprayers for a variety of spraying applications, including lawn spraying, agricultural spraying, fluid transfer, roof cleaning, dust suppression, and more. Includes a male 1/2" hose barb kit for attaching the pump to a hose with a 1/2" ID.
