Feature:1. UNIVERSAL RV PRE PRESSURE ACCUMULATOR TANK: Pressure value from 10psi125psi, suitable for most pumps on the market, possess constant pressure, reduce pump circulation, and solve the pulsation problem of RV or fresh water system on board2. EXTEND SERVICE LIFE OF PUMP: Store the water pressure of the water pipe during the peak period, buffer the impact damage caused by the high water pressure to the pump, reduce the sound and the frequent start of the pump, and provide a more stable water supply3. WIDE RANGE OF APPLICATIONS: Pre inflated pressure 10psi(0.7bar) in the tank before leaving the factory, compatible with RV, caravan, boat pressurized water system, food and beverage filling and liquid delivery and any other pressurized system to help you reduce frequent pump starts4. EASY TO INSTALL: Please read the instructions carefully before use, adjust the air pressure in the water tank to be lower than the pressure of the pump switch 3psi (0.2bar). The connection port adopt the threaded connector nozzle, connect the wing nut fittings to the energy storage end of the accumulator tank, the hose is fixed by the clamp, and connect the accumulator tank and the pump5. WIDE APPLICATION: Accumulator tank is suitable for RVs, boats, travel trailers, caravans, yachts, provide great convenience for your outdoor tripsSpecification:Item Type: Accumulator TankProduct Size: Approx. 20 x 12.7 x 11.4cm / 7.9 x 5 x 4.5inInternal Volume: 0.75L(25FL.OZ)Charging Pressure: 10PSI 0.7BARMaximum Operating Pressure: 125PSI 8.6BARAir Filling Valve: Standard automotive tire valveInlet or Outlet Diameter: 1/2in MNPTFunction: Play the role of constant pressure, prevent the system pressure from rising and falling, so that the water flow is more gentleFeatures: 1. RV Use: Can effectively absorb the excess hot gas entering the water system pipeline due to the heater, and there will be no "poof" when the faucet is opened.2. When The RV Leaks: After the long term use of the RV, the pipeline connection may be loosened, and the situation of drip water leakage may occur, resulting in frequent start up of the pump. At this time, the pressure tank can effectively reduce the number of startup of the pump.3. During The Bath:The pump start and stop frequently because of the uneven pipe and nozzle, and the pressure tank can effectively improve this situation.How It Works: 1. The pressure tank has pre charging pressure before leaving the factory.2. When the pump is started, water enters the pressure tank. When the pressure tank is filled, the pump stops working.3. When water is needed, the water in the pressure tank first enters the pipeline due to the role of the gas pressure, and the pump remains closed until the pressure in the pressure tank is less than the starting pressure of the pump, and the pump begins to work, so the cycle is repeated..Package List:1 x Pump Body2 x Wing Nut Fittings1 x User Manual
