With a 1\/2\" MNPT inlet\/outlet, a factory pre-charge of 10 PSI, and a maximum working pressure of 125 PSI (8.6 bar), the tank uses an internal rubber bladder to separate air and water. It reduces short cycling, lowers electrical and battery draw, and helps deliver steadier water flow from demand taps and showers.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this accumulator tank improve my pump's performance?\u003c\/h3\u003e\n\u003cp\u003ePlacing the tank on the pump outlet stores a small volume of pressurized water so the pump does not need to run every time a tap is briefly opened. This smooths the pump’s on\/off cycles and reduces the frequency of motor starts, which lengthens pump life and cuts energy use.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePre-charged air cushion reduces short cycling\u003c\/li\u003e\n  \u003cli\u003eInternal rubber bladder isolates air from water for consistent pressure\u003c\/li\u003e\n  \u003cli\u003eRecommended set pressure: ~3 PSI below pump cut-in\u003c\/li\u003e\n  \u003cli\u003eEasy 1\/2\" MNPT connection to typical water pump outlets\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat are the key specifications and safety notes I should know?\u003c\/h3\u003e\n\u003cp\u003eThe tank holds 0.75 liters and is rated up to 125 PSI; the factory pre-charge is 10 PSI and you should adjust it relative to your pump cut-in pressure.
