<p>This is a compact size submersible water pump(none self-prime). It's built by a brushless motor providing smooth and quiet operation than a non-brushless water pump.<br/><br/><strong>Features:</strong><br/>Brushless, permanent magnetic rotor, maintenance-free.<br/>Stator and circuit board sealed by epoxy resin.<br/>Enclosed with static sealing, not dynamic, which can avoid leaking problems.<br/>Small size, high efficiency, low consumption, low noise (less than 35db).<br/>Wide temperature resistance range from 0°C to 60°C.<br/>Used in Aquarium, car cooling, humidifier, air conditioner, other cooling and circulation systems.<br/><br/><strong><span style="color:rgb(255, 0, 0)">Note:</span></strong><br/><span style="color:rgb(255, 0, 0)">1. It can be used in the water or other liquids(without particles and impurities); NOT for acid and alkali solution.<br/>2. DO NOT dry burn the pump, otherwise it would be damaged;<br/>3. PLEASE let the pump vibrate several times in the water to exhaust air, then it can work normally.</span><br/><br/><strong>Specifications:</strong><br/>Color: Black<br/>Pump material: ABS<br/>Temperature resistance range: 0 ~ 60°C<br/>Condition of use: Continuously<br/>Power consumption: 9W<br/>Rated voltage: DC 12V<br/>Max. flow rate: 300L/H<br/>Max. lift: 450cm / 14.76ft<br/>Noise: Less than 35dB<br/>Outer diameter of inlet / outlet: 9mm / 0.35in<br/>Inner diameter of inlet / outlet: 6mm / 0.24in<br/>Waterproof class: IP68<br/>Product size: 56 * 52 * 47mm / 2.2 * 2 * 1.8in<br/>Product weight: 70g / 2.47oz<br/>Package size: 6.2 * 6.2 * 4cm / 2.44 * 2.44 * 1.57in<br/>Package weight: 79g / 2.8oz<br/><br/><strong>Package List:</strong><br/>1 * Brushless DC Pump<br/>1 * Adapter Plate</p>
