Applications
Grundfos SCALA2 is designed for pressure boosting in
one- and two-family houses and apartments.
We recommend SCALA2 for the following applications:
• pressure boosting of city mains water
• pressure boosting of water from roof tank
• pressure boosting of water from break tank
• pressure boosting of water from ground tank
• water supply from shallow wells (< 8 m).

Grundfos SCALA2 is a fully integrated, self-priming,
compact waterworks for pressure boosting in domestic
applications.
SCALA2 incorporates integrated speed control
enabling the keeping of the perfect pressure at the
taps, meaning that the pump performance will increase
with increasing demand.
SCALA2 can be installed in three easy steps:
1. Connect the pipes.
2. Prime the pump.
3. Plug the pump into the power outlet and the pump
will start.
Grundfos SCALA2 has all the components necessary
to ensure a comfortable pressure:
• intelligent controller
• integrated speed-controlled drive
• integrated pressure tank
• integrated sensors
• integrated non-return valve.
