Feature: 1. UNIVERSAL RV PRE PRESSURIZED ACCUMULATOR TANK: Pressure value 10psi-125psi, suitable for most pumps on the market, constant pressure, reduce pump circulation, and solve the pulsation problem of RV or water system on board 2. 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, reduce the frequent start of the pump, and provide a more stable water supply 3. WIDE RANGE OF APPLICATIONS: Accumulator pressure tank 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 starts 4. EASY TO INSTALL: Please read the user manual carefully before use, adjust the pressure in the water tank to be lower than the pressure of the pump switch 3psi (0.2bar), the connection ports are threaded joint nozzles, connect the wing nut fittings to the energy storage end of the accumulator tank, the hose is fixed by the clamp, and the hose connects the accumulator tank and the pump 5. APPLICABLE SCENARIO: Energy storage tanks are suitable for RVs, boats, travel trailers, caravans, yachts, providing great convenience for your outdoor travel Specification: Item Type: Mini Pressure Tank Size: Approx. 20 x 12.7 x 11.4cm / 7.9 x 5 x 4.5in Volume: 0.75L (25.3FL.OZ) Charging Pressure: 10PSI 0.7BAR Maximum Operating Pressure: 125PSI 8.6BAR Fill Valve: Standard car type tire valve Inlet Outlet Diameter: 1/2in MNPT Features: Play the role of constant pressure to prevent the system pressure from rising and falling, so that the waterflow is more gentle Function: 1. For RV Use: Effectively absorb excess heat entering the water system piping due to the heater, no poof sound when the faucet is turned on 2. For RV Water Leakage: After long term use of the RV, pipe connections may loosen, resulting in dripping water, this causes the pump to start frequently, the pressure tank can effectively reduce the frequency of water pump starts 3. During Showering: The pressure tank can effectively improve the frequent start stop of the water pump caused by uneven piping and nozzles Working Principle: 1. The pressure tank has pre charging pressure before leaving the factory 2. When the water pump is turned on, water enters the pressure tank. When the pressure tank is full, the water pump stops working 3. When water is needed, the water in the pressure tank enters the pipeline first due to the pressure, the water pump remains closed until the pressure in the pressure tank is lower than the start pressure of the water pump, the water pump starts working, repeat this cycle.
