SHYSKY Heavy Duty Low Noise 24V 120W Micro Brushless DC Water Pump DC60G-24120S-1 39ft 1003GPH, DRY RUN Protection, For Cooling Circulation Pressure Sys About this item SHYSKY DC60G-24120S-1 Water pump, Inlet Outlet: Both 3/4'' threaded, with external diameter of appr. 25mm; Max static lift 12 m (~39 ft, in pressure, 0.12MPa or 17.4PSI); Max horizontal flow rate 3800 LPH (~ 63L/Min, also, ~1003GPH). Typical feature is with good lift and flow rate, suitable for some micro/ medium circulation/ pressure/ cooling sys. Brushless DC motor, also known as EC motor; Magnetic Driven (NO DIRECT AC 100-240V POWER CONNECTION, PROHIBITED); Small size but strong; Low consumption High Efficiency; Long time continuous working with low noise;Safety - no spark, Explosion - proof; Low noise about 40dB. With typical features of 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 water cooling circulation, air compressor cooling circulation, PC server water cooling, yacht/ vehicle water cooling, and vavrious other industrial, medical and household water processing systems. Note that pump cannot be self-priming, and it is important to make sure that there exists no dry run (especially for long time) and avoid impurities in the pumping systems. Variety Power: 24V DC electric source, Battery or Solar Panel, etc; Soft Start with Low in-rush current, Especially suitable for Solar SYS who can not provide over-high startup impulse current; Constant power level when powering vol. is over 24VDC yet under 28VDC, quite useful feature in some cases. NEW FEATURE: DRY-RUN PROTECTION feature is integrated now in default. Pump works at rated voltage: When there exists no/ in-sufficient in-flow (or significant air bubble contained), it is DRY RUN scenario and protection will be triggered: Pump will access stop-run-stop-run---cycle, greatly reducing rotation speed. When flow comes sufficiently again, pump will re-access normal run. It greatly alleviates physical friction between rotor and pump body and heat generated, yet, NOT completely eliminates the friction since still running yet at lower pace.
