SHYSKY 24V DC 150W Flow/Speed Adjustable Heavy Duty Water Pump DC80E-24100A-1 150W Lift 10m (32ft) 2113GPH, Brushless Design, Stable Circulation Cooling System for Yacht Auto Application About this item [High Power Efficiency] SHYSKY DC80E-24100A-1 Heavy Duty Water pump, Both inlet and outlet G1'' threaded ports, with external diameter of appr. 32mm; Max static lift 10m (32.8ft); Max horizontal flow rate 2113GPH.Typical feature is with high flow rate and good lift value, suitable for cooling, circulation, gardening systems. SPEED/Flow Adjustable: User can modify the speed/flow of pump at work through rotating the potentiometer knob of pump. Thus, it is 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] 24V 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 24VDC yet under 28VDC, 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
