SCALA2

GRUNDFOS SCALA2 is a robust, composite, variable speed pump that adjusts performance according to water demand, providing constant pressure to all taps. The fully integrated pump includes a motor, tank, sensor, drive and non-return valve in one compact unit that is quick and easy to install. The SCALA2 is self-priming, allowing for use from both above and below ground water sources and the water-cooled motor ensures quiet operation.

Applications• Mainsboosting

• Householdwatersupply

• Pressureboostingfromabovegroundwatertanks

• Pressureboostingfrombelowgroundwatersourceseg.Belowgroundtank/dam

FeaturesVariable SpeedThe pump adjusts performance according to water demand, providing constant pressure to all taps regardless of variations in demand or inlet pressure.

Self-PrimingIdeal for pressurising water from above or below ground water sources with a suction lift of up to 8 metres and self-priming up to 4 metres.

Energy EfficientThe pump features a permanent magnet motor to help reduce power consumption while the frequency controller matches the power consumption with the required water output, also helping to conserve energy and reduce energy bills.

Simple SelectionOne model to suit most domestic applications makes selection easy.

User FriendlyThe easy to use control panel features LED indictors displaying power status, pressure setting and alarm indicator lights.

Protective FunctionsTo protect the pump and help ensure a long life, a range of protective features are incorporated into the pump such as; dry-run protection, anti-cycling alarm, auto-reset and maximum continuous operation time (30 mins).

Easy InstallationQuick and easy installation in just three steps; connect the pipes, prime the pump and plug into the power outlet.

Integrated Non-Return ValveNo additional non-return valve required - plug and pump solution.

How tHe SQ(e) protectS and reduceS wear

VolTAGE hAndlInG

Increased winding temperature caused by under voltage often reduces the lifespan of the pump. The SQ(E) motor is protected against voltage fluctuations including over and under voltage.

dry runnInG ProTEcTIon

The SQ(E) pump is factory pre-set based on minimum power consumption. Dry-running protection is activated 40 seconds after power is connected to allow priming of the pump. When there is no water in the hydraulics, power consumption is reduced. The SQ(E) stops automatically when below the dry run power limit and restarts automatically within 5 minutes after cut-out.

SQe and cu301conSTAnT PrESSurE oPErATIon

When using a CU301 controller with the SQE pump, water pressure will always remain constant regardless of how much water is being consumed. As more taps are opened, the pump automatically increases its speed, maintaining the chosen pressure at any flow rate.

PowEr lInE communIcATIon

The SQE communicates with the CU301 without the need for additional cables. If there is a failure at the pump, via the power cable, simple diagnostics can take place.

SImPlE ProGrAmmInG

The CU301 has a simple interface with up/down buttons to control the pressure of the pump. Hold both the up and down buttons for 5 seconds and the unit is locked - easy.

SofT STArT

Soft start ensures a low starting current with a smooth and steady acceleration. This offers excellent starting reliability at low voltage, prevents overload of the mains power, reduces water hammer in the pipe and reduces pump wear.

for morE InformATIon conTAcT:

PowEr SuPPly

Low ampere usage makes it possible to connect more appliances to the same fuse group or reduce the size of the power line. Small generators can be used with SQ(E).

Grundfos recommends to use a generator with a capacity 50% higher than rated pump power consumption.

The SQ(E) pump provides several features that simplify your installation and add reliability to the system.
