Features: 3-Phase brushless DC design, permanent magnetic rotor, maintenance-free, long life span Can stand high temperature fluid (typically: water) Locked-rotor and reverse connection circuit protection, automatic overload protection Soft-start with low in-rush current (could be nice for direct solar panel connection) Small size, high efficiency, low consumption, low noise Stator and circuit board sealed by epoxy resin, completely water proof Sleeve and shaft with high-precision ceramic materials Speed adjustable/ power regulation function: flow /power can be flexibly adjusted within range of 0 (almost 0) and max value pump can reach. Ways of power regulation: a. through manually rotating potentiometer knob (variable resistor), in default. b. injecting external 0-5V analog signal. c. injecting external PWM signal. (for c., it demands customization based on MOQ & lead time. Normal version in stock supports a. and b.) Specifications: Sizes and weight: 100.5mmx95.5mmx69.6mm; 650g Dimension of Inlet and Outlet: 20mm / 20mm Power Saving: 86.4W Low Noise: Less than 40dB Wide Working Voltage Range: 5-24Vdc (24Vdc rated) Max Static Head: 13M (42.5ft) Max Flow Rate: 1800L/H (475.5G/H) Fluids: Water, oil, alcohol, other non-corrosive fluids with good fluidity, etc Power Supply: can be matching battery, DC electric source or solar panel, etc Water Proof Class: IP68 (Fit for submersible installation) (Note that control box of pump is recommended to be located at normal temperature off-water location, when in application; as to pump head itself, it's completely waterproof and suitable for hot water.) Package includes: 1 x DC50B-24130A 24V Micro Speed Adjustable Brushless DC Water Pump (No power supply is included.)

Unit failed
After several months of operation for 4 hrs a day in solar water heating motor got noisy and slowed down. Disassembly showed no debree in pump. On a second unit variable speed does not work
