Never miss a beat

In a world increasingly focused on energy savings, system intelligence, and carbon reduction, pump technology must evolve accordingly. At Shinhoo, innovation is our foundation—and Master SD Series stands as our latest advancement in circulation systems.

Designed for high-efficiency, low-noise, and digitally controlled performance, Master SD represents a leap forward in how we approach HVAC, heat pumps, and solar applications.Built on decades of R&D and engineering experience, Master SD Series combines advanced motor efficiency, intelligent control, and structural durability, making it one of the most comprehensive solutions for residential and light commercial circulation applications.

Redefining Circulation with Technology-Driven Efficiency

At the heart of Master SD lies a neodymium magnet rotor, enabling up to 30% greater motor efficiency than traditional asynchronous models. Complementing this hardware is Shinhoo’s self-developed digital PCB control platform, capable of real-time response and system-level optimization, delivering up to 45% improvement in operational performance.

To further optimize energy use, the pump’s hydraulic system is engineered with CAE (Computer-Aided Engineering) simulation, achieving a remarkable 64% gain in fluid efficiency while minimizing noise and turbulence.

Smart Control. Silent Operation. Stronger System Integration.

Master SD is equipped with 12 built-in control modes, including auto-adaptive operation, PWM, constant pressure, and proportional flow modes—allowing it to seamlessly integrate with various heating, cooling, solar, and heat pump configurations.

With a noise level as low as 42 dB(A) and real-time display of power and flow, the unit delivers performance that is both intelligent and silent — ideal for today’s smart and space-conscious homes.

Built for Extreme Environments

Recognizing the diverse climates and challenging installations faced by modern systems, Master SD features:

Anti-condensation structure and thermal insulation plate to prevent internal moisture buildup

Non-corrosive polymer hydraulic components, validated by 2,000-hour salt spray and 5,000 test cycles

Protection ratings up to IPX5, making it suitable for rooftops, coastal regions, and high-humidity installations

Proven Reliability, Internationally Validated

Every pump undergoes over three months reliability testing protocol, consisting of 35 critical evaluations in CNAS-certified laboratories and in partnership with TÜV standards.

These tests include thermal cycling, durability under load, electrical safety, vibration resistance, and environmental stress testing—ensuring 100% quality assurance prior to market release.

With its compact design, ultra-low power consumption (as low as 5W), and high adaptability, Master SD is the ideal pump for new builds, retrofits, and sustainable construction projects worldwide.
