It is understood that measuring the performance of the fountain pump is good or bad, the size of the power is not important, but the unit efficiency in the same head, the same flow of cases, the efficiency of small power high, that is good performance.
Fountain pump has the highest head flow and rated head flow of the labeling method, the market most of the fountain pumps are marked with the highest head flow, and some manufacturers marked fountain pump is very outrageous, such as ordinary 90w and 120w copper pump booster pump, Standard power of 80w (maximum lift 10 meters) and 120w (maximum lift 13 meters).
Some businesses in order to achieve good sales, into 100m (maximum lift 12-15 meters) and 150m (the highest head 15-20 meters), traffic is also high scary.
