The pump is well done, the housing looks solid, the cable is long and it is terminated with a 5,5x2,1 mm socket, but the data on the label are completely at odds with the reality. The water pump works at 12 V, but at 5.5 V it probably works only with air. Rozsądny zakres napięcia podczas pracy z wodą to od 8 V do 12 V, ponieważ poniżej tej wartości wirnik pompy często nie startuje. In addition here, I describe situation when pump is running without load (hose is not connected). According to the label the efficiency of the pump is 200 l per hour, that is about 3.33 l per minute. Actually at 12 V its performance is about 1 l per minute which gives us 60 l per hour, which is definitely less than the manufacturer declares. The above tests were carried out on two pumps.

This pump is very quite. If you don't need too much flow, it is a good choice.

I am more than surprised with the amount of water flow from this pump running one 12v. I use it in a shrimp tank to pump water for filtering, running off 12v solar setup.
