Features:1. the mini water pump is quiet and powerful. The maximum flow can reach 250L/H (66GPH), and the maximum water outlet is up to 3M (9.8ft).2. Super energy saving: It can save more than 50% energy than ordinary water pump, low voltage power supply, focusing on safety. Copper motor, no carbon brush, no pollution, electronic commutation, low heat generation, high efficiency and long service life.3. The shell is made of high-quality plastic, corrosion-resistant, impact-resistant, durable, acid and alkaline ph resistant, and corrosion-resistant. The stator and motor circuit board are potted with epoxy resin, which is completely isolated from the impeller, solving the problem of water leakage caused by long-term diving of the water pump, and it is completely waterproof. The shaft core is made of high quality stainless steel.4. Lightweight mini suction cup: small and lightweight. Close the front cover, and the suction cup can be easily adsorbed on the flat surface, not easy to fall off, only 40db, keep quiet.5. Used for small desktop aquariums, waterscape decorations, hydroponic circulation pumps, pet drinkers, humidifiers, miniature fountains and other industrial water circulations, circulating water tank, automatic water feeders for cats and dogs, etc. Specification: Model: QR10D Material: Plastic Purpose: Submersible Pump Structural Principle: Centrifugal Pump Drive Mode: SolenoidMedium Supply: Pure Water Pump Impeller Structure: Semi-Open Impeller Suction Method: Single Suction Number of Impellers: 4Voltage: 12V Voltage: 5W Aximum Head: 3M (9.8ft) Maximum Flow Rate: 250L/H(66GPH) Outlet Diameter: About 8.5mm / 0.34in Cable Length: About 150cm / 59.06in with 5521D Female Plug Packing Weight: About 85g Packing List: 1 * DCU Brushless Water Pump Note: Due to the lighting effects and shooting angles, there is color difference in the product, please understand.
