Grundfos SCALA2 3-45 AKC CDE pressure booster pump 1x200-240V 50/60Hz

The SCALA2 is a complete, self-priming, compact home waterworks designed to boost water pressure. It is quiet, easy to install and maintains constant water pressure at all taps.

The SCALA2 home watermaker provides perfect water pressure at all taps. With the SCALA2 Home Watermaker, you will not experience a drop in water pressure if you open multiple taps in your home, start watering the garden and run the washing
machine.

It is equipped with a motor with frequency converter, pressure vessel, pressure and flow sensor and check valve. It is compact, easy to install and offers one of the lowest noise levels in its class thanks to its water-cooled motor.

Constant water pressure in up to 8 taps open simultaneously

The SCALA2 domestic water heater is ideal for homeowners with low or fluctuating water pressure. With a variable frequency drive motor and smart pump control, it provides constant water pressure in homes with up to 3 floors and 8 taps. It operates only when needed and automatically adjusts to the water demand, making it energy efficient.

Abuilt-in flow sensor measures the inlet pressure and intelligent pump control regulates the pump speed according to the homeowner's settings, ensuring constant water pressure throughout the house.

High energy efficiency and low running costs

Thanks to improved hydraulics, permanent magnet motor and speed control, the SCALA2 home water pump is extremely efficient. It intelligently adapts its performance to water consumption, increasing energy efficiency and extending the life of the pump.

The SCALA2 adapts the motor speed to the water consumption. The speed increases with the number of open taps and decreases when closing them, thanks to an integrated sensor that measures the inlet pressure and compares it with the desired pressure. The sensor communicates with the control unit that controls the frequency converter.

By choosing SCALA2, energy consumption can be reduced by up to 40% by replacing an older water plant. This efficiency is achieved through real-time motor speed control, minimized cycling and reduced energy consumption at low demand.

Lowest noise level on the market

Thanks to its improved hydraulic housing and water-cooled motor, the SCALA2 achieves a noise level of just 44 dB(A), a 50% reduction in noise. This noise level is equivalent to a quiet library environment or a quiet dishwasher. The SCALA2 is much quieter than traditional fan-cooled motor systems, which have noise levels in excess of 72 dB(A) and cause discomfort due to vibration. 

The SCALA2 is installed in four steps

• Connect the pipe (adjustable up to +/- 5°).
• Water the pump (filled with at least 1.7 litres of water).
• Plug into an electrical socket (default pressure setting 3 bar).
• Set the filling pressure to 70% of the desired value.
