Pull the engine carburetor primer two to three times to prime the carburetor.ħ. Prime the fuel/oil injection pump by compressing the fuel and oil priming bulbs until they are firm.Ħ. Connect the fuel hose to the fuel tank and open the vent on the fuel tank cap.ĥ. Attach the fuel tank to the top of the pump frame. Check the fluid levels in the fuel tank and oil tank. Close the pump discharge valve and make certain that the tee-handle screw on the rapid priming port is tight.ģ. Connect hoses to suction, discharge, and exhaust connections.Ģ. Open the discharge valve momentarily to allow trapped air to escape.ġ. If the pump is operated for more than 15 to 20 seconds with the discharge valve closed, it may begin to cavitate and speed up due toĪccumulation of air in the casing.
If pressure does not show on the pressure gauge, stop the pump and check all suction hose connections and gaskets. The tank consist of a single hose fitting, a fuel tank cap with an integral fuel gauge, a manually operated vent screw, and an explosion suppression arrangement (Explosafe).ĭo NOT run the pump more than 20 seconds unless pressure shows on the The gas tank is a 6-gallon tank mounted on top of the pump frame. The exhaust hose carries the toxic engine exhaust gases to the atmosphere. The pump must not be operated in a confined space unless the exhaust hose is connected to the pump. The foot valve should be completely submerged when the pump is operating. The suction screen should rest in clear water-not in mud or debris, which might be drawn into the pump. If the pump fails to draw water or if the discharge nozzle shows and uneven stream, look for a poor connection allowing air leakage into the suction side. The strainer should be completely submerged in water. Be sure that proper-size gaskets are used at all of the suction connections. It is hand primed up to a suction lift of 16 to 20 feet.īefore operating the P-250 Mod 1, make sure that all of the suction hose connections between the foot valve and the pump are tight.
The P-250 Mod 1 can pump 250 gpm at 125 psig. When used for dewatering, it draws a large volume of waterįrom flooded compartments and discharges it into the sea. When used for fire fighting, the P-250 Mod 1 draws water from the sea and pumps the water through suitable hoses and nozzles at a high pressure. It is used in fire fighting and in dewatering operations. The P-250 Mod 1 is a gasoline-driven portable pump with an internal-combustion engine.
