Ceramic Shaft DC 12V 24V Submersible Water Pump 800L/H 5m Head Brushless Motor Low Noise Booster for Rockery Fish Tank​ ​

DC Brushless Submersible Water Pump - Ceramic Shaft 12V/24V Small Booster PumpKey Specifications:Voltage:DC12V (working range: DC 7-14V) | Power: 19WDC24V (working range: DC 5-28V) | Power: 22WPerformance: Flow rate 13L/min; Max head 5.5MStyles: Bare wire / DC female connector (5.5x2.5mm)Dimensions: Approx. 8×7×5cm (plastic bag packaging); Weight: 220g (plastic bag) / 226g (white box)Core Features:Durable Ceramic Shaft: High-precision zirconia ceramic shaft (or optional stainless steel) ensures wear resistance and stable operation.Long Lifespan: Brushless motor with electronic commutation eliminates carbon brushes, reducing pollution; epoxy potting isolates stator/PCB from rotor for full waterproofing (no leakage).Low Noise & Vibration: Adjustable shock-absorbing silicone base reduces vibration and noise for quiet operation.Reliable Performance: Ultra-low failure rate (Flexible Use: Wide voltage compatibility; optional speed control (PWM, 0-5V analog, potentiometer); stackable for doubled head; suitable for both submersible and external use (external use requires lower water level than inlet).Package Contents:Choose style: 1 × Submersible Water Pump (Bare wire / DC 5.5x2.5mm connector)Packaging: Plastic bag (default) or optional white boxNotes:Color Variation: Due to material and lighting, minor color differences from images may occur, but performance remains consistent.Size Deviation: Manual measurement may cause slight dimensional differences (±0.2cm), which do not affect functionality.Usage Tips:1. Must be submerged in water or connected with inlet below water level for proper operation (air must be discharged from inlet).2. Avoid continuous operation above 65°C for pumps over 24W; consult professionals for specific usage environments.3. Do not run dry; max head refers to vertical height with zero flow, while listed flow is horizontal output.4. Working current reduces to 70-85% of max (open water current) when connected to systems.p{margin-block-start: 0; margin-block-end: 0}
