12V DC Brushless Submersible Water Circulation Pump Key benefits and features Reliable hot water circulation: designed to move hot water in solar water heating systems, hydronic heating, and other applications that require steady water flow. Temperature tolerance: operates at temperatures up to 100 C (212 F) with a maximum fluid temperature of 110 C, suitable for hot water circuits. Ultraquiet operation: delivers noise levels below 35 decibels, as low as 30 dB at 1 meter, thanks to a performance ceramic shaft and sleeve design that minimizes vibration and friction. Waterproof submersible design: epoxy resin potting completely isolates the motor stator and circuit board from the rotor, enabling underwater installation and longterm submersion in both hot and cold water. Strong, efficient performance: maximum flow of 8 L/min (2.1 GPM) with a 3 meter (9.8 ft) maximum water head, while consuming low power with a rated current of only 0.7 A. Specifications and characteristics Voltage: 12V DC Motor type: brushless Flow (max): 8 L/min (2.1 GPM) Head (max): 3 m (9.8 ft) Current: 0.7 A Operating temperature: up to 100 C (212 F) Maximum fluid temperature: 110 C Noise: 35 dB, as low as 30 dB at 1 m Construction: fully waterproof with epoxy resin potting; ceramic shaft and sleeve; suitable for underwater installation Applications and use scenarios Solar water heating systems requiring reliable hot water movement and circulation. Hydronic heating or radiant floor systems needing a quiet, efficient pump to circulate hot water. Submerged water circulation in hot or cold water environments, including installations where the pump operates while fully submerged. Notes This pump is designed for lowpower, efficient operation in 12V DC systems and emphasizes durability in submerged and hot water conditions without sacrificing performance.
