SCALA2: Noiseless pumps for accurate water pressure


In residences and commercial buildings, pressure boosting has become an important element in distributing water, especially with the onset of summer, to ensure consistent water pressure is maintained. Unmanaged or excessive pressure could waste water while reducing the life cycle of pipes and other equipment. Often, pressure boosting pumps also consume high levels of energy. Intelligent pressure management solutions can take this functionality to the next level by adapting to the pressure on any dynamic consumption requirements, without the need to compromise on having a loud pump system. This being one of the best added feature of having a noiseless pump system such as SCALA2. A noiseless pump integrated with adaptive pressure boosting is the comfort testament to owning a Grundfos SCALA2 system.

Grundfos India, a leader in advanced pump solutions and a trendsetter in water technology has launched an effective solution to address pressure boosting challenges. SCALA2 is a fully integrated water booster that can always provide the perfect water pressure across all taps.

The solution combines a pump, motor, tank, sensor, drive and non-return value into a singular, compact unit. With its intelligent pump control system, SCALA2 can adjust inlet pressure from the tank and the outlet pressure at the tap.

Unlike conventional pumps, SCALA2 has an extremely low noise level of 47dB. This is achieved with the help of a permanent magnet motor that reduces noise and a water-cooled operation. A conventional motor compounds the noise through its vibration and wear and tear.

Additionally, the pressure boosting system uses a variable frequency drive to save up to 80 per cent energy in comparison to its conventional counterparts and at the same time detect leaks. This is particularly beneficial in reducing the dependency on traditional energy and further decreasing electricity costs for the end user.

Accuracy in water pressure
The built-in sensor in the pump has the ability to measure discharged pressure. If the current pressure drops below pre-decided parameters, the solution will boost operation to increase overall pressure and mitigate the loss of pressure.

On the other hand, if the pressure in the pipelines exceeds the maximum parameter, SCALA2 will be able to manage the pressure and reduce it to standard settings. As an advanced feature, SCALA2 will turn off the booster after 30 minutes of continuous operation suspecting wastage or leakage.
