Performance and Reliability for Your Home
At Nordik Radiant, we are proud to present the Grundfos SCALA1 3-45 115 V booster pump, a modern and intelligent solution designed to improve water pressure in homes, cottages, and off-grid installations.
Developed by Grundfos, a global leader in pumping technology, the SCALA1 combines consistent performance, easy installation, and smart technology to deliver optimal everyday comfort.
The Problem of Low Residential Water Pressure
Low water pressure is one of the most common issues in residential homes. Weak showers, poorly performing appliances, everyday discomfort: the majority of households face this problem. In general, 80% of residential users are affected.
It is in this context that Grundfos developed the SCALA1, a modern, compact, and intelligent booster pump designed to meet today’s standards for comfort, performance, and reliability.
A Pump Designed for Residential Comfort
The SCALA1 3-45 is a multistage booster pump featuring a high-performance self-priming function, capable of drawing water from depths of up to 8 meters in less than five minutes. This makes it an ideal solution for installations supplied by a cistern, storage tank, or shallow well.
Thanks to this technology, the pump:
- Significantly reduces the risk of losing prime,
- Effectively adapts to water level variations,
- Ensures stable water supply, even under demanding operating conditions.
This intelligent design also helps limit issues related to dry running and air entering the piping system, enhancing overall system reliability.
A Pump Ready to Operate Upon Installation
The SCALA1 3-45 115 V is designed for quick and easy commissioning, with no need for additional external components or complex adjustments:
- No external pressure switch required
- No expansion tank required
- Factory settings already optimized
Start-up is simple:
1. Connect the suction and discharge pipes (1" NPT)
2. Prime the pump during initial startup
3. Connect the power supply
In just a few steps, your booster system is ready to deliver reliable and consistent water pressure.
Twin Pump Mode (Optional)
For installations requiring higher flow or added redundancy, the SCALA1 can be installed in Twin configuration:
- Duty / standby
- Assisted duty (increased flow rate)
Flow increases while pressure remains constant.
Smart Technology and Bluetooth Connectivity
The SCALA1 features built-in Bluetooth connectivity for use with the Grundfos GO app.
With the app, you can:
- Monitor pressure and flow in real time
- Receive alerts and diagnostics
- Adjust settings according to usage (home, irrigation, tank)
The pump operates perfectly without the app, but it provides advanced control for users and installers.
Technical Performance – SCALA1 3-45
The 3-45 model offers an excellent balance between flow and pressure for residential use.
- Power supply: 115 V / 60 Hz
- Power: 950 W (~0.79 HP)
- Nominal flow rate: ≈ 14.9 gpm (3.6 m³/h)
- Maximum head: 45 m (≈ 4.5 bar)
- Maximum system pressure: 8 bar (115 psi)
- Noise level: < 55 dB(A)
Its quiet operation makes it ideal for installation near living areas.
Flexible Suction Modes
The SCALA1 adapts to different water sources thanks to its integrated modes:
- Municipal supply pressure boosting (Positive Pressure): Automatically maintains constant pressure, ideal when public water supply pressure is insufficient.
- Suction from a tank or shallow well (Suction Lift): The pump can draw water from up to 8 meters deep, perfect for cisterns, shallow wells, or rainwater harvesting systems.
- Automatic air handling (Air Handling): Purges air from the system to ensure stable and quiet operation from installation.
Ideal Applications
The Grundfos SCALA1 3-45 115 V is suitable for many applications:
- Single-family homes and apartments
- Water tanks and off-grid systems
- Residential irrigation and watering
- Light agricultural applications or workshops
The pump is designed for outdoor installation (rain-resistant), but it must never be installed in a flood-prone area and is not submersible.
Simple and Intuitive Control
The SCALA1 3-45 is factory preset to operate immediately as a booster pump. No complex configuration is required.
The control panel includes:
- On / Off button
- Reset button
- Bluetooth button
- LED indicators for status and alarms
Even without the app, the pump operates perfectly upon installation.
Conclusion
The Grundfos SCALA1 3-45 115 V is an intelligent, reliable, and quiet booster pump, perfectly suited to modern residential needs.
Easy to install, high-performing, and safe, it is a durable choice for both homeowners and installers.
A simple, efficient solution from Grundfos for optimal water pressure, day after day.
