ALPHA2 is the best pump to withstand the tough conditions in a heating system, and with four newly added features, it just got even tougher. 

Robust start-up
Shakes free any impurities before the pump starts at the beginning of the heating season.

Summer mode
Adjustment of the pump’s performance in the summer to the warmer temperature outside – giving customers extra energy efficiency.

Magnetite resistance
Ensures that no small pieces of metal get stuck in the pump’s vital parts when they are magnetised.

Dry-running protection
Makes sure the pump never runs without liquid in the system.

Add to that unrivalled energy efficiency, easy installation and the fact that ALPHA2 covers both your heating demands and up to 90 percent of your air-conditioning and cooling demands.

Perfect water pressure – finally compact and easy to install
SCALA2 is a fully integrated water booster pump providing perfect water pressure in all taps at all times – even with multiple taps and showers running at the same time. It packs pump, motor, tank, sensor, drive and non-return valve into one compact unit. And with its intelligent pump control, SCALA2 automatically adjusts performance to both inlet pressure and water consumption in the home. Thanks to a water-cooled motor, SCALA2 even offers one of the lowest noise levels of any booster on the market.

What is intelligent pump control?
SCALA2 features a built-in sensor, which constantly measures the discharge pressure. If the pressure drops below the desired level, SCALA2 boosts its operation immediately to compensate for the loss of pressure. We call it intelligent pump control and the result is perfect water pressure.

Perfect water pressure: Intelligent pump control adjusts operation automatically
Low noise: As quiet as a modern dishwasher (47 dB(A) in typical use)
Easy selection: One variant for all domestic boosting needs
Easy installation: Compact, all-in-one solution, plug-and-pump
Easy to operate: User-friendly control panel
Reliable operation: Dry-running protection, anti-cycling
Long lifetime: Quality-tested to perfection, maintenance-free
SCALA2 is the perfect choice for residential buildings with up to 3 floors and 8 taps.

Boosting from mains: Increases the water pressure delivered by city mains
Boosting from tanks: Increases water pressure from roof tanks, break tanks and ground tanks, including rainwater tanks.
Boosting from wells: Pumps water from a depth of 8 metres

Product range
