Feature:1. Universal Compatibility: With a pressure range of 10psi to 125psi, our pre pressurised tank suits most RV pumps, offering consistent pressure and mitigating freshwater system pulsations.2. Pump Longevity Enhancement: By storing peaking line water pressure, our tank cushions against high pressure damage, reducing noise and frequent pump activations for a stable water supply.3. Versatile Applications: Pre charged to 10psi, it's suitable for RV, marine, food, and liquid systems, minimizing pump starts and integrating seamlessly with pressurized systems.4. Easy Installation: Simply adjust the tank pressure 3psi below the pump switch, using threaded fittings and clamps for secure hose attachment, following the manual for excellent setup.5. Wide Application Range: Suitable for RVs, boats, trailers, and yachts, this tank enhances outdoor travel convenience by ensuring steady water flowing during your adventures.Specification:Item Type: Pre Pressurized Accumulator TankMaterial: PA Plastic Size: Approx. 30x14.4cm / 11.81x5.67inVolume: 1L (33.8FL.OZ)Charging Pressure: 10PSI/0.7BARMaximum Operating Pressure: 125PSI/8.6BARAir Fill Valve: Standard Car Style Tire ValveInlet Outlet Diameter: 1/2in MNPTApplication: Plays a role in maintaining constant pressure, preventing the system pressure from fluctuating and making the water flowing smoother.1. for RV Use: It can effectively absorb the excess heat that enters the water system pipes due to the heater, and there will be no "poof" sound when turning on the faucet2. for RV Leakages: After long term use, pipe connections may loosen, resulting in drip leakages that cause the water pump to start frequently. The pressure tank can effectively reduce the frequency of water pump startups.3. During Showering: Improves water pump frequency startups caused by uneven pipes and nozzles, creating a more consistent water flowing.Working Principle: 1. The pressure tank is pre charged with 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 pipes first due to the pressure of the air bladder. The water pump remains off until the pressure in the pressure tank drops below the starting pressure of the water pump, at which point the water pump starts working, repeating this cycle..Package List:1 x Pump Body2 x Nut Joint2 x Hose Clamp1 x PTFE Tape1 x Instruction Manual
