JT-750 DC Water Pump for solar water heating and underfloor heating circulation with 1.2m³/h flow rate

This Jiatong JT-750 series DC water pump provides efficient circulation for domestic heating applications where DC power availability makes it particularly suitable for solar thermal systems. The pump's engineering plastic construction and non-blocking design ensure reliable operation with clean water, while its compact 0.18kg weight and horizontal installation orientation simplify integration into existing heating circuits. Available in multiple threaded connection configurations, the pump offers installation flexibility for retrofit and new-build applications alike, with voltage compatibility spanning DC12-24V to match various solar array outputs.

Features and Construction

The JT-750 pump incorporates several practical features designed specifically for heating system applications where reliability and energy efficiency matter. Its construction and operating principles prioritise consistent performance with minimal maintenance requirements.

Material and Build

Constructed from engineering plastic, the pump housing and components provide chemical resistance suitable for clean water applications while preventing corrosion issues common in heating systems. The semi-open impeller design with six impellers creates a non-blocking flow path that reduces the risk of debris accumulation, maintaining consistent performance over time. This material choice also contributes to the pump's light 0.18kg weight, making installation and handling straightforward even in confined spaces.

Size and Practical Fit

With suction and outlet diameters of 20/25mm, the pump accommodates standard heating system pipework dimensions used in domestic installations. The horizontal pump shaft position allows for flexible mounting orientations, while the threaded connection system provides secure joining without requiring specialised tools. Four distinct configurations (B4, B5, D4, D5) offer both 4-point and 5-point threaded options, ensuring compatibility with various international pipe standards and existing installations.

Uses and Placement

This DC water pump serves specific applications where its technical specifications match the requirements of modern heating systems, particularly those incorporating renewable energy sources or requiring precise circulation control.

Event or Professional Use

For solar heating system installers, the pump's DC12-24V operating range makes it directly compatible with photovoltaic outputs, eliminating the need for inverters or AC conversion equipment. The 1.2m³/h flow rate combined with adjustable 3-7 metre head pressure allows technicians to match circulation performance to specific system designs, whether for domestic solar water heating or supplementary underfloor heating circuits. The multiple configuration options mean installers can standardise on one pump model while accommodating different connection requirements across projects.

Everyday Home Use

Homeowners with existing solar thermal systems benefit from the pump's energy-efficient operation, drawing between 0.015-0.035kW while maintaining heating circuit circulation. The non-blocking design reduces maintenance concerns, and the engineering plastic construction ensures longevity without corrosion issues common with metallic pumps in heating applications. For underfloor heating systems, the adjustable head pressure allows fine-tuning of circulation to match zone requirements, potentially improving system efficiency and comfort levels.

Benefits and Buying Value

When selecting a circulation pump for heating applications, several practical considerations influence the purchasing decision beyond initial cost, particularly regarding long-term reliability and installation flexibility.

Reuse and Low Maintenance

The engineering plastic construction combined with the non-blocking impeller design creates a pump that resists common failure modes in heating systems. Without metallic components subject to corrosion, the pump maintains performance consistency across heating seasons, while the semi-open impeller design prevents debris accumulation that can reduce flow rates over time. This translates to reduced maintenance interventions and longer service intervals compared to some conventional circulation pumps.

Why Choose This Product

The JT-750 DC water pump offers specific advantages for heating system applications where DC power availability, compact dimensions, and connection flexibility matter. Its direct compatibility with 12-24V DC systems makes it particularly valuable for solar thermal installations, eliminating conversion losses associated with AC pumps. The multiple configuration options within one product family simplify inventory management for installers while ensuring homeowners receive exactly the connection type their system requires. With measurable performance specifications including 1.2m³/h flow and 3-7m head pressure, users can make informed decisions based on their specific circulation requirements.
