SHYSKY Speed/Flow Adjustable Smart Brushless Water Pump DC55E-12120A 12VDC 54W 12m 39ft 528GPH Low Noise, For Water Circulation Pressurization Cooling sys

[Speed Adjustable] SHYSKY DC55E-12120A Water pump, with external diameter of 20mm, outlet: G1/2, with external diameter of 20mm; Max static lift: 12 m; Max horizontal flow rate: 2000 LPH (33L/Min). Submersible, IP68 waterproof; Typical feature is with quite high lift (output pressure) value, but with relatively low flow rate, suitable for some micro pressure system; Speed/Flow Adjustable: User can adjust working power/ flow of pump at work through rotating potentiometer knob of pump, flexible at use
[BLDC design] Brushless DC motor, also known as EC motor; Magnetic Driven (NO DIRECT AC 100-240V POWER CONNECTION, PROHIBITED); Small size but strong; Low consumption and High Efficiency; Long time continuous working with low noise;Safety - no spark, Explosion - proof; Low noise about 40dB
[Wide applications] Low-voltage safety, high power-efficiency, low noise at normal work and supporting long-time continuous reliable running. This pump is widely applied for fountain landscape, medical equipment cooling circulation, air compressor cooling circulation, PC server water cooling, yacht/ vehicle water cooling, or other industrial, medical and household water processing systems. Pump cannot be self-priming, and it is important to make sure that there exists no dry run (especially for long time). Avoid impurities in the pumping systems
[Variety Power] 12V DC electric source, Battery, Solar Panel, etc; Soft Start with Low in-rush current, Especially suitable for Solar SYS who can not provide instant startup impulse current; Constant power level when powering vol. is over 12VDC yet under 14VDC, quite useful feature in some cases
[Dry Run Protection] DRY-RUN PROTECTION feature is integrated on the pump design now in default. Pump works at rated voltage: When there exists insufficient in-flow or no in-flow (or significant air bubble within), pump's DRY-RUN protection will be triggered: Pump will access stop-run-stop-run-stop-run--- cycle, greatly reducing rotation in this context. When in-flow comes sufficiently again, pump will then re-access normal run performance. This DRY-RUN protection is aimed to significantly reduce physical damage of pump from long time DRY RUN in some scenarios. Otherwise, pump could be conveniently dead due to long-time DRY RUN
