JT-750 Series DC Water Pump for Solar Heating and Floor Heating Boosting Applications

The Jiatong JT-750 series represents a specialised DC-powered water pump engineered specifically for clean water circulation in domestic heating systems. Designed as a process pump with non-blocking characteristics, this unit serves as an effective booster for solar water heating installations and underfloor heating circuits where reliable fluid movement is essential. Its compact engineering plastic construction provides a corrosion-resistant solution that maintains performance while minimising weight and installation complexity. With multiple voltage and connection configurations available, the pump offers flexibility for integration into various 12V or 24V DC systems commonly found in renewable energy and heating applications.

Features and Construction

The JT-750 pump incorporates several design elements that make it suitable for heating system applications where consistent water circulation is required. Its construction focuses on reliability and compatibility with the clean water medium specified for use, avoiding complications that might arise with more demanding fluids.

Material and Build

Manufactured from engineering plastic, the pump housing and internal components benefit from the material's inherent resistance to corrosion and chemical degradation when used with clean water. This construction approach contributes to the unit's remarkably light 0.18 kg weight, reducing strain on mounting points and simplifying handling during installation. The plastic composition also supports the pump's non-blocking performance characteristics, with smooth internal surfaces that minimise flow resistance and prevent debris accumulation in properly maintained systems.

Size and Practical Fit

With standardised 20/25 mm suction and outlet diameters, the pump connects readily to common piping used in domestic heating installations. The horizontal shaft orientation provides straightforward mounting options, while the semi-open impeller design with six vanes creates efficient water movement within the compact footprint. These physical characteristics combine with the single-stage jet pump principle to deliver the specified 1.2 cubic metre per hour flow rate across a head range of 3-7 metres, offering sufficient pressure for typical booster applications in residential heating circuits.

Uses and Placement

This DC water pump finds its primary application in heating systems where controlled water circulation enhances performance and efficiency. Its design parameters align particularly well with renewable energy installations and modern heating approaches that benefit from precise fluid management.

Event or Professional Use

For solar thermal installations, the pump serves as a circulation booster that maintains optimal heat transfer from collectors to storage tanks, particularly in systems where natural convection proves insufficient. Professionals installing underfloor heating might incorporate the unit to ensure even heat distribution across larger floor areas or multi-zone systems. The availability of both 4-point and 5-point threaded connection variants (designated B4/B5 and D4/D5 models respectively) allows installers to select the configuration matching existing plumbing interfaces without requiring adapters or modification.

Everyday Home Use

Homeowners with existing DC-powered heating systems can utilise this pump to improve circulation in solar water heating setups, potentially enhancing hot water availability. Its modest 0.015-0.035 kW power consumption makes it suitable for operation from battery banks or photovoltaic systems without excessive energy draw. The pump's clean water specification makes it appropriate for closed-loop heating circuits where water treatment prevents scaling and corrosion, maintaining the non-blocking performance over extended periods.

Benefits and Buying Value

The JT-750 series offers practical advantages for heating system enhancement through its specialised design and configuration options. These benefits centre on compatibility, reliability, and straightforward integration rather than dramatic performance claims.

Reuse and Low Maintenance

Engineering plastic construction provides inherent durability in clean water applications without requiring protective coatings or regular corrosion prevention measures. The non-blocking design reduces maintenance needs by minimising opportunities for debris accumulation within the pump mechanism. When properly installed with appropriate filtration, the unit can operate for extended periods with only periodic system checks rather than intensive servicing routines.

Why Choose This Product

Selection of the JT-750 pump is justified by its specific matching to DC-powered heating applications, with voltage options covering common 12V and 24V systems. The availability of multiple threaded connection types (4-point and 5-point) eliminates compatibility concerns during installation. Its measurable performance parameters—1.2 m3/h flow and 3-7 metre head—provide concrete expectations for system designers planning booster pump integration. Unlike generic water pumps, this unit's specifications align precisely with the requirements of solar thermal and underfloor heating applications where controlled, reliable circulation matters most.
