The key to their success lies in sophisticated control technology.
Advanced Control and Operation
Grundfos pumps are more than just motors and impellers.
They are smart systems that think for themselves.
The CMBE TWIN
The CMBE Twin is a powerhouse for light commercial buildings.
It excels in locations like schools, small offices, and multi-family homes.
Its core intelligence comes from several key features working together.
- Cascade Control: The system runs one pump for low demand. The second pump automatically starts only when flow requirements exceed the first pump's capacity. This saves significant energy.
- Pump Alternation: To ensure even wear, the system alternates which pump is the lead. This equalizes operating hours and extends the lifespan of both units.
- Multi-Master Functionality: If one pump becomes unavailable, the other can take full control of the system. This provides a critical layer of redundancy and reliability.
The SCALA1 TWIN
Designed for domestic and light commercial use, the SCALA1 is all about connectivity.
It uses built-in Bluetooth for configuration and control.
The Grundfos GO REMOTE app makes setup incredibly simple.
You can easily configure the twin system for either duty/assist or duty/standby mode directly from your smartphone.
This model offers a fully integrated, compact solution for modern pressure boosting needs.
Installation and Design Flexibility
Grundfos systems are known for their ease of installation.
The CMBE Twin, for example, is a compact, all-in-one unit mounted on a baseplate.
This pre-assembled design simplifies the process significantly.
Feature | Grundfos CMBE Twin | Grundfos SCALA1 Twin |
---|---|---|
Primary Application | Light Commercial | Domestic, Light Commercial |
Control Technology | Cascade Control, Multi-Master | Bluetooth via GO REMOTE app |

RAFSUN: The High-Tech Contender Redefining Performance
Are you seeking cutting-edge technology that prioritizes durability and intelligence?
RAFSUN integrates advanced electronics and superior materials.
This creates a booster pump built for the most demanding modern applications.
RAFSUN combines a high-efficiency Permanent Magnet Synchronous Motor (PMSM) with a Variable Frequency Drive (VFD).
This delivers perfectly constant pressure with ultra-quiet operation.
Its robust design features 14 safety protections and a waterproof-sealed circuit board for unmatched reliability.
RAFSUN represents the next generation of water pressure boosting technology.
The design philosophy is centered on creating a pump that is not only powerful but also incredibly smart and durable.
This approach is evident in every component, from the motor to the controller.
Core Technology and Unmatched Durability
At the heart of every RAFSUN pump is the synergy between its motor and controller.
VFD + PMSM Motor
This combination is the key to its superior performance.
The VFD adjusts the motor speed in real-time to match water demand precisely.
This ensures a constant, stable pressure without fluctuations.
The PMSM motor is highly efficient and contributes to the pump's ultra-quiet noise level of under 50dB.
Built to Last
RAFSUN places a heavy emphasis on long-term reliability.
This is achieved through premium materials and a groundbreaking approach to protecting the electronics.
- UltraShield PCB Potting: The main controller is completely sealed in a potting compound. This makes it 100% waterproof (IP67 rated), protecting it from moisture, dust, and condensation. This innovation can extend the controller's life by 3 to 5 years.
- Premium Materials: The pump features high-grade components like AISI304 stainless steel impellers and high-precision NSK bearings for maximum corrosion resistance and longevity.
Intelligent Operation and Protection
A powerful pump is only as good as its control system.
RAFSUN's system is both highly intelligent and user-friendly.
"14-Shield" Protection
The pump is equipped with a comprehensive suite of 14 different safety protections.
This system guards against everything from dry-running and overheating to voltage fluctuations and freezing.
The dry-run protection is particularly smart.
It uses a multi-stage recovery algorithm that attempts to self-prime, then rests for progressively longer periods to conserve energy while waiting for water to return.
Smart Twin Pump Mode
RAFSUN systems offer an intelligent twin pump link mode.
This allows two pumps to work together seamlessly.
The system automatically manages the pumps based on demand.
This provides both higher flow capacity and a fully redundant backup system for ultimate reliability.
Optional WiFi functionality also allows for complete remote control and monitoring from a smartphone.
This focus on advanced technology and robust engineering makes RAFSUN a powerful choice for B2B distributors seeking a competitive edge.
Conclusion
DAB and Grundfos offer proven reliability and versatility.
RAFSUN provides a technologically superior alternative with exceptional durability and smart features.
Your best choice depends on prioritizing established reputation versus next-generation performance.
Frequently Asked Questions (FAQs)
What is the benefit of a twin booster pump system?
A twin system offers increased water flow to meet higher demand.
It also provides redundancy, as one pump can operate if the other needs service.
How does a twin booster pump increase flow but not pressure?
The pumps are connected in parallel.
This setup doubles the volume of water moved, but the pressure output remains that of a single pump.
Can twin booster pumps save energy?
Yes, smart systems with VFD technology and cascade control save energy.
They only run the second pump when necessary, matching power use to demand.
What does duty/standby mean in a twin pump system?
One pump is designated as the primary "duty" pump.
The second "standby" pump only activates if the primary pump fails, ensuring reliability.
What is cascade mode on a booster pump?
In cascade mode, the second pump turns on to assist the first one.
This happens only when water demand exceeds the first pump's maximum capacity.
Are booster pumps noisy?
Modern VFD booster pumps are designed for quiet operation.
Many models from top brands operate at noise levels below 55 dB, which is very quiet.
What kind of maintenance do twin booster pumps require?
Routine maintenance includes checking for leaks and cleaning inlet filters.
You should also periodically verify the control panel settings and ensure proper function.
Can I control my booster pump remotely?
Yes, many modern booster pumps offer remote control.
Brands like DAB, Grundfos, and RAFSUN have models with WiFi or Bluetooth for app-based monitoring.
