The BDD 12V Solar Heat Water Pump Black is a compact, high-efficiency DC brushless circulation pump designed for solar water heating systems, hot water circulation, cooling systems, aquaponics, hydroponics, fountains, and various low-voltage water transfer applications. Featuring a durable ABS housing and advanced brushless motor technology, this pump delivers reliable performance, low power consumption, and an extended operating life of over 10,000 continuous hours.
Engineered for use with 12VDC power systems, the pump provides an impressive flow rate of up to 800 litres per hour while maintaining quiet operation below 40dB. Its energy-efficient design consumes only 19W of power, making it an ideal solution for solar-powered installations, battery-operated systems, and off-grid applications where power efficiency is essential.
The pump utilizes a high-quality wear-resistant shaft and electromagnetic drive system to ensure smooth, stable operation and reduced maintenance requirements. Its open impeller design delivers efficient water circulation while maintaining reliable performance across a wide range of operating conditions.
Designed specifically for circulating hot water, the BDD Solar Heat Water Pump supports liquid temperatures between 1 C and 60 C, making it suitable for solar water heating loops, domestic hot water circulation systems, greenhouse heating systems, and other temperature-controlled water applications.
The unit features standard 1/2-inch male threaded inlet and outlet connections, allowing straightforward installation into existing pipework and plumbing systems. With a maximum water lift of 5 metres, the pump can efficiently move water through solar collectors, storage tanks, circulation loops, and low-pressure water systems.
As a centrifugal brushless pump, it requires water to be present in the system before operation and is not self-priming. For optimum performance and longevity, the pump should never be operated dry and should only be used with clean water or compatible fluids within the specified temperature range.
