I have gained the pump to hochzupumpen from a river water. For this I must convey about 6 feet up the water. That worked first did not. I first had the whole pump incl. Suction hose get full of water. All connections have to be completely sealed since otherwise, air is sucked in. If all that is full of water, does the pump their service perfectly. I can not write much about the amount of water, since it depends on the head. However, I have a 1000l tank get fully in about 45 minutes. The pump runs pleasantly quiet (I was expecting more noise).
They are obtained virtually anywhere for just 50, but can they can also send up. Accessories (connectors and Suction) but cost twice as much. Nevertheless, it is worth the money anyway. Similar products cost 50-100% more loosely.
