The pump easily reaches 6 bar. Be careful, it needs a proper filter and not just a simple mesh if it's for drinking water. Do not use throttling, i.e., reducers at the inlet and outlet, because otherwise it makes a terrible whistling noise. It is also noisier compared to the previous one, but in its current location it won't bother the neighbors. And most importantly, it uses half the watts of the previous one. If you combine it with an electronic controller, make sure it allows adjustment for differential and pressure. Simple electronic controllers stop only when they reach their nominal pressure, i.e., 6 bar. With a mechanical one, pay attention to the differential.
