Designed for the agriculture and landscaping industries, this Shurflo 8007-543-850 Bypass Diaphragm Pump achieves a maximum flow rate of 1.8 gpm, making it perfect to use on sprayers on the farm or around the yard for agricultural spraying, heavy-duty spraying, and fluid transfer applications.
This 12-volt electric bypass pump from Shurflo features Viton valves and a Santoprene diaphragm for chemical resistance. This allows you to pump a wide range of general agricultural chemicals, such as liquid fertilizers, herbicides, pesticides, insecticides, and other hard-to-handle fluids.
The electrical packaging includes a built-in rocker-type manual switch with international on/off switch symbols that is protected from the elements by a clear boot and 2 pin connector on power leads. The wiring is neatly routed into the molded assembly through form fitting entries and strain relieved inside the housing to protect the wiring and provide a neat appearance.
Bypass Pump Applications: Bypass pumps come in handy in applications where an automatic demand switch isn't required. They are useful in applications where frequent stopping and starting of the motor is required and in applications where a wide range of flows and pressures are required (eg. spray bar with multiple nozzles, all controlled independently). Bypass pumps continue to run regardless of pressure in the system. For the spray bar example above, the flow rate is different when one nozzle is turned on compared to having two or more nozzles turned on. Once the nozzles are turned off, excess flow is bypassed within the pump.

We recommend using the TeeJet AA122-1/2-PP Poly Line Strainer (see Related Products) to help eliminate contaminants from running through your bypass pump. Bypass pumps require pressure regulators, and we recommend the TeeJet 23120-1/2-PP Poly Regulator (see Related Products).
