The raw water washdown pump, when activated, creates pressure in the raw water washdown system . When the hose nozzle is
closed, water pressure within the system increases to the design specifications, once reached, the pump automatically shuts off .
When the hose nozzle is open, releasing water from the system, the pressure in the system decreases . When the pressure decreases
to a predetermined point, the pump automatically turns ON and increases the pressure . The system settings ensure a steady flow of
water every time the raw water washdown is used .
