Bundle includes 2 Items: (1) Shurflo 8000-543-238 Automatic-Demand Diaphragm Pump with (1) Male 3/8" Hose Barb Kit. The Shurflo 8000-543-238 Diaphragm Pump provides up to 1.8 gpm open flow and 100 psi maximum pressure for optimal performance in a wide range of spraying applications. Its unique conical valve design delivers flow rates at maximum discharge pressures, making this high pressure pump suitable for lawn spraying, heavy-duty agricultural spraying, and fluid transfer applications on spot sprayers or agricultural sprayers used around the farm and home. This high pressure Shurflo 8000 series pump is one of the more well-known agricultural pumps used across North America due to its reliability and performance in the field. The 100 psi demand switch is useful for applications requiring a set flow and pressure (ex. spray wands on spot sprayers). The demand switch only operates when liquid flow is required and automatically shuts the pump off when no flow is required, saving battery life. Includes a male 3/8" HB kit to attach the pump to a hose with a 3/8" ID.
