Manufacturers seeking household water pumps

Thread Content

The buyer wants to use a water pump; the well is 12 meters deep, with the water level estimated to be around 9 meters. There are two elbows in the pipe before it reaches the pump – do these elbows affect the suction lift? The head is 7 floors high, approximately over 20 meters; the pipe outlet well is 25 in diameter. Which type of water pump is suitable? What are the disadvantages of screw pumps and impeller pumps respectively? There are about 10 elbows in the outlet pipe before it enters the water tower; do these elbows affect the head pressure? The water pump cannot be installed underground, as the water inlet consists of 25-mm steel pipes that are inserted directly into the ground, leaving no space for installation. I would appreciate some advice from those who are knowledgeable in this area. Which is better, an impeller pump or a screw pump? Thank you!
