BL90CM 24V BID PWM

DC-driven circulation pump with brushless motor, 24V, with a built-in driver (magnetic isolation) and PWM speed control. Rated for continuous operation, can be used both submerged and on land (not self-priming), and is suitable for water, oil or normal acid/alkaline liquids. Powered via solar panel, battery, adapter or other power source.
