Description: The accumulator tank holds a reservoir of air and water down stream from the pump. The air acts as a cushion, absorbing pressure variations creating a smoother flow and reducing the cycling of the pump,especially at lower flows. Low power consumption, no noise during use, avoiding frequent opening of the safety valve and frequent refilling of the automatic water replenishment valve.Features: Internal Bladder Smoother flow Reduces on/off switch cycling Quieter water system Long pump life Easily fitted to new or existing systems Compact size 1/2" MNPT port fittings Mounting point for optional pressure switchSpecifications: Condition: 100% Brand New Type: Water Accumulator Tank OE Number: 182-200, 182200 Internal volume: 0.75L Pre-charged pressure: 10 PSI Max operating pressure: 125 PSI Inlet/outlet diameter: 1/2" MNPT Comes with (2) 1/2" barbed fittings Approvals: CEPackage Includes: 1x Accumulator 2x ConnectorApplications: -Yacht/RV/caravan pressurized water system -Sprayer fixtures (vehicle-mounted and electric sprayer) -Clean machine, humidifier, water purification and medical apparatus -Food beverage filling and liquid transfer -Any other pressurization systemNote: 1. Relieve air pressure prior to disassembly 2. Do not use to pump flammable fluids, gasoline, kerosene fuel oil, ect. 3. Do not use pump in a explosive environment or use where flammable vapors are present 4. Do not use to pump gasoline, Petrol or fluids with flash point below 37C(98F), explosion or death may occur. 5. The accumulator tank comes pre-pressurized at 10 PSI. Before Using Adjust air pressure in tank 3 PSI(0.2 bar) below water pump switch cut in pressure. 6. Do not over pressurize tank. Pressures over 125PSI(8.6BAR) may rupture tank and cause personal injury.
