Never miss a beat

For heat pump systems, underfloor heating mixing stations, and HVAC integrators, pump efficiency, control accuracy, and refrigerant compatibility are critical to system performance and regulatory compliance. The Shinhoo Grand 25-23 Pro – a permanent magnet variable frequency pump – delivers ultra low energy consumption, precise flow feedback, and an A3 explosion proof rating. It provides a safe, high efficiency circulation solution for systems using R290 and other eco friendly refrigerants.

IE5 Efficiency – EEI ≤ 0.23

The Grand 25-23 Pro achieves an EEI value as low as 0.23 (Part 2), far exceeding EU energy efficiency standards. Its high efficiency permanent magnet motor offers:

l Rated flow: 8 m³/h

l Rated head: 12.5 m

l Max. flow: 14 m³/h

l Max. head: 23 m

While delivering strong hydraulic performance, the pump minimizes energy consumption – helping systems earn green building certifications and meet low carbon operation targets.

Multiple Control Modes – Flexible Adaptation

The pump supports constant speed, constant pressure, proportional pressure, AUTO, and PWM control modes, easily adapting to different operating conditions. Whether in constant flow or variable flow systems, it delivers precise adjustment and avoids unnecessary energy waste.

High Accuracy Flow Feedback – Stable & Reliable

Flow feedback accuracy reaches ±0.2 m³/h, providing dependable data for system monitoring and optimization. Combined with IP44 protection, the pump ensures long term stable operation even in humid or mildly dusty environments.

A3 Explosion Proof – R290 Refrigerant Compatible

Certified with an A3 explosion proof rating, the Grand 25-23 Pro is specifically designed for systems using flammable eco friendly refrigerants such as R290. It meets safety requirements for heat pumps, chillers, and refrigeration equipment – helping customers address increasingly stringent environmental and safety regulations.

Global Certifications – Proven Quality

The pump holds CCC, TUV, CE, EMC, ROHS, and REACH certifications, confirming electrical safety, electromagnetic compatibility, and material environmental compliance. System integrators can specify the pump with confidence, shortening compliance review cycles.

Typical Applications

l Heat pump systems (air source / water source heat pumps)
