In today’s modern HVAC systems, where energy efficiency and comfort are top priorities, circulation pumps play a critical role as the driving force of fluid dynamics. Shinhoo Master SD Series circulation pumps stand out with advanced intelligent control and exceptional energy performance, establishing themselves as the next-generation solution for efficient heating and cooling systems.

Intelligent Control for Quiet and Stable Operation

Equipped with adaptive algorithms, Master SD Series adjusts pump operation in real time through PWM signals. Multiple speed modes allow the pump to meet diverse system requirements for flow and head. Combined with a permanent magnet synchronous motor and low-noise design, the pump achieves highly efficient performance with a noise level as low as 42 dB(A), ensuring a quiet and comfortable environment.

Ultra-High Efficiency with Certified Energy Savings

Master SD Series achieves an outstanding EEI ≤ 0.20 (Part 2) energy efficiency rating, proudly carrying Europe’s Energy Efficiency Class A certification. Compared to conventional pumps, it reduces energy consumption by more than 20%. Featuring a full copper motor with Class H insulation, the pump is built for durability, high-temperature resistance, and reliable long-term operation even under continuous heavy loads.

Wide Compatibility Across HVAC Systems

Designed for versatility, Master SD Series supports CP/CS/PP operating modes, making it adaptable to underfloor heating, radiators, hot water circulation, and cooling systems. For more demanding or corrosive environments, an optional plastic pump body ensures rust-free performance and extended lifespan.

Smart Protection and Easy Monitoring

The pump integrates intelligent air venting and anti-blocking functions, automatically eliminating trapped air and preventing impeller jamming for uninterrupted operation. A clear display provides real-time data on flow and power, allowing users to monitor system performance at a glance and quickly identify any faults.

Robust Structure, Sustainable Design

Built with multiple layers of electrical and mechanical protection, Master SD Series maintains high reliability even in intensive operating conditions. Its anti-condensation design enhances adaptability in challenging environments. At the same time, the pump’s eco-conscious engineering aligns with modern sustainability goals.

Powering the Future of Efficient HVAC

With whisper-quiet operation, industry-leading efficiency, and intelligent system integration, Master SD Series redefines what circulation pumps can achieve. Whether in residential or commercial settings, it delivers consistent, reliable, and sustainable circulation power.

As environmental policies tighten and high-demand applications expand, the market places greater emphasis on the comprehensive performance of pumps. Mega S Pro Series was developed to meet these challenges, delivering cutting-edge technology and sustainable design to provide silent, efficient, and reliable solutions for modern industrial fluid systems.

Innovative Design for Energy Efficiency

Equipped with ultra-high-efficiency motors, optimized hydraulic models, and advanced frequency control technology, Mega S Pro Series achieves an Energy Efficiency Index (EEI) of below 0.23 — setting a benchmark in the industry. Compared with traditional pumps, the series reduces overall energy consumption by 20% to 50%, significantly lowering electricity costs while promoting sustainable, low-carbon operations.

Reliability That Lasts

Built for long-term stability, Mega S Pro Series integrates 15 protection mechanisms within its control circuits. Core components undergo durability simulation testing and material reinforcement. The impeller is made of hydrolysis- and alcoholysis-resistant polymers, while the shield adopts 304 stainless steel, ensuring rust-free performance in high-temperature, high-humidity, and corrosive environments. This design reduces replacement frequency and minimizes lifecycle maintenance costs

Ultra-Quiet Operation — Noise <39 dB(A)

Through 3D flow channel simulation and low-vibration impeller design, Mega S Pro Series effectively suppresses hydraulic noise. At full load, the 200W model operates below 39 dB(A), while the 1800W model remains at just 56 dB(A) — equivalent to the silence of a library. This makes it an ideal choice for noise-sensitive environments such as hospitals, laboratories, and high-end manufacturing facilities.

Intelligent Control & User-Friendly Interface

Mega S Pro Series features a TFT LCD display with Chinese/English switching, multi-curve visualization, and real-time flow/head monitoring. With 12 control modes (including constant pressure, constant flow, temperature, and differential temperature) and three communication protocols (Modbus, CAN, LIN), the system enables dual-use heating/cooling, precise temperature regulation, and accurate flow control.

Technology That Creates Value

Mega S Pro Series is more than a pump — it represents a forward-looking response to the industry’s demand for reliability, sustainability, silence, and intelligence. By combining technological innovation with environmental responsibility, Shinhoo continues to deliver solutions that help global customers achieve higher performance and long-term value.
