This DC-powered water circulation pump provides reliable fluid movement in renewable energy and heating applications, operating on low voltage DC current from 12 to 24 volts. With its engineering plastic construction and compact 0.18-kilogram design, the pump fits efficiently into solar thermal systems, underfloor heating circuits, and other clean water circulation requirements where DC power availability makes traditional AC pumps impractical or less energy efficient.
The JT-750 pump combines straightforward mechanical design with practical electrical specifications for heating system applications. Its horizontal shaft orientation and single-stage jet pump principle deliver consistent water movement without complex installation requirements.
This DC pump serves specific applications where low-voltage operation aligns with system requirements or offers installation advantages over AC-powered alternatives.
Practical advantages emerge from the pump's specific design choices and performance parameters, offering solutions to particular installation challenges.

JT-750 DC Water Pump for Solar Water Heating and Underfloor Heating System Circulation

Features and Construction

Material and Build
Engineering plastic forms the primary construction material for this clean water pump, providing corrosion resistance and suitability for water temperatures typically encountered in heating systems. The semi-open impeller design with six individual impellers creates the pumping action, operating without suction capability but offering non-blocking performance when handling properly filtered water. This material choice balances durability with weight considerations, resulting in the 0.18-kilogram total mass that simplifies handling during installation.Size and Practical Fit
The pump accommodates standard pipe connections with both 20mm and 25mm suction and outlet diameters, matching common heating system tubing dimensions. Its compact physical size allows installation in limited spaces within boiler cabinets, solar thermal system components, or underfloor heating manifolds. The horizontal pump shaft position follows conventional installation practices, while the 0.015 to 0.035-kilowatt power range provides adequate energy for circulating heated water without excessive electrical consumption.Uses and Placement

Event or Professional Use
Solar water heating installations benefit from direct DC pump integration, eliminating power conversion losses when connecting to photovoltaic systems or battery banks. The pump's 1.2 cubic metre per hour flow rate and 3-7 metre head capability suit residential-scale solar thermal collectors, while the 12V/24V operation matches common off-grid and renewable energy system voltages. Professional installers can select from multiple thread configurations - including 4-point and 5-point thread options in both B and D series models - to match existing system connections without additional adaptors.Everyday Home Use
Underfloor heating systems utilise this pump for secondary circulation or booster functions, particularly in extensions or zones where existing central heating pumps lack sufficient capacity. Homeowners with solar thermal installations appreciate the direct DC operation that integrates with solar controller outputs, while the clean water specification ensures compatibility with closed-loop heating systems containing inhibitor-treated water. The pump's non-blocking characteristic maintains performance in properly maintained systems without demanding frequent maintenance interventions.Benefits and Buying Value

Reuse and Low Maintenance
The engineering plastic construction resists corrosion from clean water applications, supporting extended service life in properly maintained heating systems. With no specialised lubrication requirements and straightforward electrical connections, ongoing maintenance remains minimal beyond occasional system checks. The horizontal shaft orientation follows conventional pump mounting practices, allowing replacement of existing failed pumps without system redesign.Why Choose This Product
Select this DC water pump when your application requires low-voltage operation, particularly with solar thermal systems or battery-powered heating solutions. The specific flow rate and head range address common residential heating system requirements, while the compact dimensions fit space-constrained installations. Multiple thread configuration options - including JT-750B4, JT-750B5, JT-750D4, and JT-750D5 variants with both 12V and 24V versions - provide flexibility for different connection requirements without needing additional adaptors or modification components.
