The pump piping shall be flexible to prevent any breakage caused by vibration.
The pump shall be capable of a maximum discharge volume of 80 GPM. at 10 PSI, and a maximum discharge pressure of 150 PSI while pumping 20 GPM. In the center of the performance curve, the pump shall be capable of pumping 50 GPM at 100 PSI.
The pump shall be driven by a 4-stroke Honda gasoline powered, 6.5 horsepower single cylinder engine. The engine shall be air cooled, 12 volt electric start with recoil backup. The engine shall be fueled from a 1.5 gallon fuel tank which is to be mounted on the engine. The engine shall be connected with a quick disconnect weather proof style connection.
A control panel shall be supplied and installed on the pump. The controls shall consist of a master switch, master discharge pressure gauge and panel light for night operations.
SELF PRIMING SYSTEM
The pump engine shall be equipped with a self priming system capable of 10′ – 15′ lift for fast positive priming.
All piping on the suction side shall be made of steel (welded joints) schedule 40. The suction piping, the pump and the discharge shall be tested to 400 PSI.
The suction piping shall consist of a 2.5″ tank to pump line with a 2.5″ flexible rubber hump hose to minimize flex and vibration between the pump and the tank.
Between the tank and the pump there shall be a 2.5″ industrial valve. This valve shall remain open to pump from the tank. This pipe shall have a tee into the suction side of the pump, and shall continue to the rear of the truck for overboard suction. The overboard suction connection shall have a 2.5″ NST male adapter and a 2.5″ NSTF cap with retaining cable.
Other openings will be utilized accordingly when pre-connects, booster reels and other accessories that require pressurized water are specified.
All valves larger than 1″ shall be a fire service type drop out style ball valve which shall have a hard-coated anodized, high-strength, light-weight aluminum alloy body with rugged stainless steel ball and two PTFE seats.
The valves shall be capable of bi-directional flow with a minimum working pressure rating of 250 psig.
All stainless steel parts shall be made from 300 series material. The valves shall NOT require lubrication of the seats or any other internal waterway component and shall be capable of swinging out of the attached waterway plumbing for easy maintenance, with the removal of six (6) to eight (8) bolts.
