Complicated selection, sizing or installations?

Selecting and sizing a booster pump can be difficult, time-consuming and complex. And with the wrong components, installation times can be longer, and the demands of the pressure boosting system may not be met.

Selecting and sizing a booster pump – where to begin?

There are many different components involved in the design and build of a domestic pressure boosting system. It can be difficult to know which booster pump best meets the needs of your application, and which components you need to install for an optimally sized system. Selecting the wrong pump, tank or pressure controller can cause up to four hours’ lost time on re-sourcing the correct components.

Long and complex installation

Traditional boosting systems are complex. Their many different components include expansion tanks, pumps, valves and control systems. All these elements need to be built into one solution. The higher the complexity, the longer the installation time, with a greater risk of buying the wrong components. Time spent sourcing components or re-fitting pipes can increase installation time by up to two hours. The added costs can result in customer dissatisfaction and wasted business time.

Limited installation space

Limited space is the most common issue in a water pressure booster pump installation. In most cases, this means having to extend the system to find alternative space or trying to fit it into the existing installation. This is complex, takes time and can lead to unhappy customers. Installing a booster system that does not fit the space can increase installation time by up to two hours and incur extra costs due to the additional piping and fittings required.

A compact, all-in-one solution

The Grundfos SCALA water pressure boosters are all-in-one booster pumps that integrate all components into one compact unit. They are quick and easy to install, saving you time for other jobs. As a multi-purpose solution, they are built for every domestic indoor and outdoor application. Selection and sizing is therefore less complex than traditional boosting systems.


Quick and easy booster pump installations

As a fully integrated, all-in-one solution, our SCALA can be installed in four steps:

  1. Connect the pipes. Inlet and outlet connections are adjustable by up +/- 5°, making installation even easier
  2. Prime the pump. The large prime plug enables you to fill water quickly and easily. You must fill the pump with a minimum of 1.7 litres or 0,45 gallons of water.
  3. Plug the pump into a power outlet and start it up. 
  4. Adjust the tank. Pre-charge pressure according to the setpoint (70% of the set pressure).

Check out our short SCALA2 installation tutorial to see how it works.

By default, SCALA2 delivers a water pressure of 3 bar (43psi), regardless of inlet pressure and the number of open taps. Essentially, this rules out any commissioning time. 

For installation of SCALA1 step 1 to 3 are the same as for SCALA2 but for fast and easy commissioning of SCALA1, configure the pump with ease using the pump control panel. To get the most out of the pump, use the Grundfos GO app and follow the guided online configuration.
