SCALA2 pump
Grundfos SCALA2 is a fully integrated, self-priming,
compact waterworks for pressure boosting in domestic
applications.
SCALA2 incorporates integrated speed control, enabling
the ability to keep perfect pressure in the taps, which
means that the pump performance will adjust to the
increasing demand.
6.1 Motor
The highly efficient motor with a permanent magnet is
water-cooled and equipped with sealed, greased-for-life
ball bearings to ensure silent operation and minimum
service.
It has a built-in thermal switch and requires no additional
motor protection.
6.2 Features and benefits of SCALA2
• Perfect water pressure.
•
All-in-one integrated booster.
• High energy efficiency.
• Easy selection.
• Compact.
• Low noise < 47 dB(A) with typical use.
6.2.1 Perfect water pressure
SCALA2 is equipped with an integrated sensor that
measures the pressure discharged from the pump. The
sensor sends a signal to the pump control and compares
the measured pressure level with the desired pressure
level, which is the pressure set according to the
homeowner's needs.
If there is a dif
ference between these two measurements,
the pump control signals the frequency converter to
increase or decrease the pump speed, thus maintaining a
constant pressure in the system.
6.2.2 Self-priming
A self-priming pump ensures a stable operation, even if
the pump is not fully filled with liquid. The self-priming
pump is able to lift liquid from below the inlet level and
handle a mix of air and liquid until the pump reaches a
fully-primed pumping condition.
6.2.3 Robust design
The pump is designed for long and trouble-free operation.
Aluminium construction combined with excellent
corrosion-resistant internal components ensure high
robustness in operation.
6.2.4 Easy installation
SCALA pumps can be installed in three easy steps:
•
Connecting the pipes.
• Priming the pump.
• Plugging the pump into a power outlet.
The pump will start running after it has been plugged into
a power outlet.
6.3 Protection features
6.3.1 Dry-running protection
The product incorporates dry-running protection that
automatically stops the pump from running without
liquid. Dry-running protection means less risk of pump
damage and lower maintenance costs.
6.3.2 Anti-cycling function
The anti-cycling function prevents the product from
starting and stopping too often in case of a minor leakage
in the system or if a tap has not been closed completely
.
The anti-cycling function will stop the pump, and an alarm
will be indicated.
6.3.3 Maximum runtime
The maximum runtime function is a timer that can turn the
pump off if it runs continuously for a certain amount of
time. For SCALA2, this time period is 30 minutes.
