The Grundfos SCALA2 (3-45) is a compact self-priming pressure pump supplied here with two hose pipes, designed to deliver constant water pressure to every outlet in your home. It is an all-in-one unit pump, motor, tank, sensor, and controls in a single housing rather than a pump-and-separate-tank arrangement.
What it does, and when you need it. If your shower goes weak the moment someone opens a tap elsewhere, or your rain shower dribbles rather than pours, your water pressure is the problem. The SCALA2 fixes it by maintaining constant pressure automatically: the pump adjusts its speed continuously to hold pressure steady no matter how many outlets are running, rather than switching hard on and off. For a household where several bathrooms are used at the same time, that continuous adjustment is what keeps the pressure even instead of surging and dropping.
Why the SCALA2 is different from a conventional booster pump. Most pressure pumps pair a pump with a separate pressure tank and cut in when pressure falls below a set point. The SCALA2 integrates everything into one compact unit and varies its speed to match demand which means quieter running, steadier pressure, and a much smaller footprint than a pump-plus-tank installation. Grundfos is the reference name in pumps, and the SCALA2 is its best-known domestic model for exactly this reason.
Supplied with two hose pipes, so the connections you need on installation are included.
Sizing it right. Pressure pumps must be matched to your home: too small and you still get weak showers, too large and you have paid for capacity you never draw. Tell our team your bathroom count, whether you run rain showers, and how many outlets might run at once, and we will confirm the SCALA2 suits your home or point you to the right alternative.
