JT-750 DC Threaded Water Pump for Solar Heating and Floor Heating Booster Applications

This Jiatong JT-750 series DC water pump provides a dedicated solution for circulating clean water in closed-loop systems, particularly where low-voltage DC power is available or preferred. As a process pump designed for non-blocking operation, it serves as a booster for solar water heaters and hydronic underfloor heating circuits, transferring media with a flow rate of 1.2 cubic metres per hour. Its electric drive mode and horizontal pump shaft position make it straightforward to install in typical domestic plumbing setups, offering a practical component for enhancing thermal distribution efficiency without requiring AC mains power conversion.

Features and Construction

The pump's performance is defined by several key specifications that determine its fit for purpose in heating and hot water applications. Its construction and operational parameters are outlined to help identify the correct model for your specific pipework and electrical setup.

Material and Build

The pump body and key components are manufactured from engineering plastic, a material selection that contributes to the unit's light 0.18 kg weight and offers suitability for use with clean water, minimising corrosion concerns. The design follows a jet pump structural principle, operating as a single-stage unit. This construction is geared towards reliable performance in its stated role as a process pump for conveying clean water, focusing on functional durability inherent to its specified materials rather than unclaimed premium attributes.

Size and Practical Fit

Physical integration is facilitated by threaded connections, with specific models offering either 20mm or 25mm suction and outlet calibres. The product line includes variants with 4-point or 5-point thread types (JT-750B4, B5, D4, D5), allowing selection to match existing pipe fittings. The horizontal shaft position is a standard configuration for easy mounting. Its compact form factor, indicated by the minimal weight, is designed for installation within the constrained spaces often found in heating system plant rooms or alongside solar thermal arrays.

Uses and Placement

This DC pump is intended for specific closed-loop water systems where consistent circulation is needed to maintain temperature or pressure. Its performance parameters guide its application in both renewable energy and comfort heating contexts.

Event or Professional Use

In professional or installed system contexts, such as integrated solar thermal installations for domestic hot water, this pump acts as a circulation booster. Its ability to operate on 12V or 24V DC makes it directly compatible with systems using photovoltaic panels or battery banks, eliminating the need for an inverter. The specified 3-7 metre head range indicates it can overcome pressure losses in typical small-scale system pipework, ensuring adequate flow to the heat exchanger or storage tank.

Everyday Home Use

For residential hydronic underfloor heating systems, this pump can serve as a supplementary booster to improve hot water circulation through the floor loops, particularly in extensions or zones where the primary system's pump may be insufficient. The non-blocking performance claim suggests a design tolerant of the clean, treated water typically used in such sealed systems. Homeowners benefit from the low-power DC operation, which can integrate with smart energy management or off-grid setups where AC power consumption is a concern.

Benefits and Buying Value

The value of this component lies in its specific design matching the technical requirements of modern low-voltage heating and hot water systems. It addresses practical installation and operational needs without superfluous features.

Reuse and Low Maintenance

The engineering plastic construction and clean-water-only mandate suggest a design aimed at reducing maintenance issues related to corrosion or scale buildup in compatible systems. As a dedicated component, its value is realised through reliable operation within its specified parameters, contributing to the longevity of the broader heating system when used correctly. The product does not make explicit lifespan claims, but its material choice and defined use case support a practical expectation of sustained performance.

Why Choose This Product

This pump is selected for scenarios requiring a specific DC voltage input, particular thread sizes (20mm/25mm, 4-point/5-point), and a performance envelope of 1.2 m³/h flow and 3-7m head. It is a match for system designs where these exact specifications are required, such as replacing a failed unit or building a new circuit based on these parameters. The range of model codes (e.g., JT-750B4-12V, JT-750D5-24V) allows precise selection for voltage and connection type, ensuring compatibility and avoiding adaptation costs.
