Grundfos Hydro Multi-S pressure booster systems consist of two or three identical CM close-coupled horizontal multi-stage, CMV close-coupled vertical multi-stage or CR multi-stage in-line pumps connected in parallel. The pumps are mounted on a common base frame and a control cabinet with a circuit breaker for motor protection and integrated controller. Automatic pump operation is based on system demand and controlled by pressure switches (one for each pump). You get a reliable, highly efficient and service-friendly solution for pressure boosting and tank filling clean water in flats, hotels and schools. The Hydro Multi-S is also well suited for emergency operations as it is factory pre-assembled, compact and offers plug-and-pump installation.

The Hydro Multi-E booster set presents a highly reliable and versatile pressure booster solution that provides you with plug-and-pump installation, fast and easy set-up and optimal energy efficiency. Unique to the Hydro Multi-E is its lack of a conventional control unit. In this intelligent solution, the control of the system lies within the pumps, which are able to communicate with each other. Since each pump can function as the controlling unit, there is full redundancy if a sensor or pump should fail. Use together with Grundfos GO for remote monitoring of your installation in apartment buildings, hotels, hospitals, schools, irrigation, wash and clean systems and fire hydrants.

The Hydro MPC range is the premium offering in the Grundfos portfolio of Hydro pressure-boosting solutions. Hydro MPC booster sets offer superb pressure control, optimal energy efficiency, and are the premium choice for any job where constant pressure is a must.

A booster set from the Hydro MPC range is able to handle the operational challenges of any boosting application, and its easy set-up and connectivity makes it the preferred choice for complex systems in buildings, industrial processes and water utility installations.

SCALA2 is the future of integrated pressure boosting solutions, featuring pioneering technology that delivers constant water pressure, low noise, energy efficiency, and maximum reliability for homes and apartments.

Designed with intelligent pump technology and robust materials, it combines all the components of a conventional pressure booster into a compact, all-in-one solution. This ensures a perfect fit in smaller spaces and streamlines the entire installation process.

Key benefits

Constant pressure in up to 8 taps in the home

The SCALA2 is the ultimate solution for homeowners dealing with low or fluctuating water pressure in the home. Either caused by fluctuations in inlet pressure and/or multiple taps open in the home, resulting in noticeable changes in water flow and temperature.

SCALA2 tackles these challenges with its frequency-driven motor and integrated control features, which ensure perfect water pressure in homes with up to 3 floors and 8 different taps*. It operates only when needed, automatically adapts to home water consumption habits and uses the right amount of energy to maintain pressure as efficiently as possible.

Its built-in sensor measures the outlet pressure and compares with usage point pressure, such as a tap or showerhead, making any necessary adjustments automatically. The intelligent pump control directs the frequency converter to regulate pump speed based on the homeowner’s chosen settings, ensuring consistent water pressure all throughout the home.

World-class energy performance saving costs for homeowners

Equipped with advanced hydraulics and a permanent magnet motor, the SCALA2 is an exceptionally efficient variable speed booster pump. It intelligently adjusts to home water demand, enhancing energy efficiency and extending the pump’s overall lifespan.

Unlike fixed speed booster pumps that consume excessive energy by maintaining a constant / fixed speed, SCALA2 adapts its energy use based on specific demand. This is achieved through an integrated sensor that measures and compares inlet pressure with the desired pressure at the point of use, such as a showerhead or bath tap. The sensor communicates with the pump control for seamless adjustments and – guided by the homeowner’s chosen pre-sets – directs the frequency converter to regulate pump speed, guaranteeing perfect water pressure in the home.
By selecting the most efficient pressure boosters over traditional booster pumps, homeowners can enjoy significant savings, reducing their energy consumption for water boosting by as much as 40%*. This exceptional energy efficiency is achieved through real-time motor speed adjustments, minimised cycling and reduced energy consumption during periods of low demand.

The most silent operation in the market

Thanks to its upgraded hydraulic cover, the new generation of SCALA2 achieves optimal water pressure and has a noise level as low as 44 dB(A). This is a 3 dB(A) reduction in sound pressure compared to the previous generation, translating to a 50% noise reduction to the human ear.

A 44 dB(A) noise level is like the quiet environment of a library or a residential area at night. Compared to common household appliances, the noise level is as low as a quiet dishwasher*.

When comparing SCALA2 to traditional pressure boosting systems with a motor fan and a noise level above < 72 dB(A), there is a big difference. These systems are far noisier than modern booster systems, causing discomfort inside and outside the home. The noise level results from poor pump technology and fan-cooled motors, both of which contribute to noticeable vibrations throughout the system.
