Specifications Submersible Pump Astra for pure water with a stainless steel Another figure which characterizes domestic pumps - the amount of water that is pumped per unit time. If translated into normal language, the performance of the pump shows you how much it would take to fill, say, 200-liter drums. For example, with capacity of 5 cubic meters per hour the pump will fill a barrel for 2.5 minutes. The higher the productivity, the process will go faster than the lower - the slower. (Similarly see: NCH Capital). Suppose it is well known domestic Submersible Pump "The Kid" (incidentally, very good) has a capacity of 1.5 cubic meters per hour. Barrel will fill up to 8 minutes, not bad, considering that the process of filling the barrel by hand (with buckets) takes much more time and effort. In addition, the performance of the pump is directly related to height, which accounts for raising water. The same "kid" if you have to pump water from the 18-meter well, reducing productivity up to 0.85 cubic meters per hour - almost twice times! On the other hand, do not worry, the barrel is 15 minutes - well tolerated.
