SHYSKY DC40F-2460 Micro Brushless DC Water Pump 24V 28W, 253GPH 19ft, Waterproof, 1/2 inch threaded ports, Safe Low Noise Stable Long-term Work, Submersible or Land Use, For Small cooling, gardening

Excellent compact centrifugal pump! Delivers great volume and handles head pressure well. Very quiet. I'm using this pump to drive a reef tank kalkwasser reactor. Works excellent! Highly recommend.

It packs a lot of punch for its size. Very quiet and low power consumption. Using on a marine ac unit that has r32 freon that requires a lower flow rate than some newer units using r410 which requires more water flow. Works good with my unit. Check water flow requirements of you unit. This pump is 3gpm at24v less than 2gpm at 12v

Pump is noisy and water output is less than claimed. I compared this 235gph pump to my other 24v pump rated at 211gph and this one is weaker with less pressure.

I use this pump for a DIY flood coolant system for a cnc mini mill. Excellent pressure, washes chips away. I coupled it with a screw-on filter, and I pump Fusion Cool 2240 mixed at 10%. This pump is a workhorse.
