Jiatong JT-750 DC Water Pump for Solar Heating and Underfloor Heating Systems

This Jiatong JT-750 series DC water circulation pump provides efficient water movement for residential and commercial heating applications, particularly suited to solar water heating systems and underfloor heating circuits. Operating on 12-24V DC power, it integrates seamlessly with solar panel arrays and battery banks for off-grid or supplementary heating solutions. The engineering plastic construction ensures reliable performance with clean water while maintaining lightweight operation at just 0.18kg. Available in multiple threaded connection variants, this horizontal shaft pump delivers consistent pressure across heating systems with minimal power consumption.

Features and Construction

The JT-750 DC water pump incorporates practical design elements for heating system applications, balancing performance with installation flexibility. With clear specifications for flow, pressure, and electrical requirements, users can match the appropriate model variant to their specific heating circuit needs.

Material and Build

Engineering plastic components form the core construction of this water pump, providing corrosion resistance and compatibility with clean water systems. The non-blocking design prevents debris accumulation in heating circuits, while the semi-open impeller structure maintains consistent water movement without excessive turbulence. This material choice contributes to the lightweight 0.18kg total weight, reducing strain on mounting points and plumbing connections during installation and operation.

Size and Practical Fit

Threaded connections measuring 20mm or 25mm diameter provide secure plumbing integration, available in both 4-point and 5-point thread configurations to match existing heating system fittings. The horizontal pump shaft orientation allows straightforward mounting in typical heating circuit layouts, while the compact dimensions facilitate installation in confined spaces near solar collectors or underfloor heating manifolds. The six impeller stages generate the specified 3-7 metre head range within the 1.2 cubic metre per hour flow capacity.

Uses and Placement

This DC water pump serves specific heating system applications where reliable water circulation supports temperature distribution and system efficiency. The electrical specifications and connection options determine its optimal placement within different heating configurations.

Event or Professional Use

In solar water heating installations, the 12-24V DC operation allows direct connection to photovoltaic arrays or battery banks without inverter conversion. Professional installers can select between the 12V and 24V variants based on available power sources, while the threaded connections provide secure, leak-resistant joins in pressurized systems. The jet pump structural principle ensures consistent performance in closed-loop heating circuits where water quality remains controlled.

Everyday Home Use

For residential underfloor heating systems, this pump maintains water circulation through floor circuits with minimal power consumption at 0.015-0.035kW. Homeowners benefit from the non-blocking design that prevents system failures due to minor debris, while the clean water specification ensures compatibility with standard heating system fluids. The horizontal orientation suits typical underfloor heating manifold installations where space constraints often dictate component positioning.

Benefits and Buying Value

Choosing this specific DC water pump involves practical considerations around heating system compatibility, installation requirements, and long-term reliability. The available specifications provide clear guidance for matching the product to existing or planned heating infrastructure.

Reuse and Low Maintenance

The engineering plastic construction resists corrosion in heating system environments, supporting extended service life with clean water operation. The non-blocking design reduces maintenance requirements by preventing debris accumulation that could impair flow or damage components. With only clean water as the specified conveying medium, the pump avoids complications associated with more demanding fluid handling applications.

Why Choose This Product

This Jiatong JT-750 DC water pump offers specific advantages for solar heating and underfloor heating applications through its DC operation, threaded connections, and clean water specification. The multiple model variants allow selection based on available voltage (12V or 24V) and thread configuration (4-point or 5-point), providing flexibility for different installation scenarios. With measurable performance specifications including flow rate, head range, and power consumption, users can verify compatibility with their existing heating systems before purchase.
