Tips: How to Install the Water Well Pump?

  1. The installation position of the water pump should meet the requirements of the allowable vacuum height, and the foundation must be level and stable to ensure that the rotation direction of the power machinery is consistent with the rotation direction of the water pump.
  2. If there are multiple units in the same room, there should be a distance of more than 800mm between the units and between the units and the wall.
  3. The suction pipe of the pump must be well-sealed, and elbows and gate valves should be minimized. Air should be exhausted when filling and diverting water. Air should not accumulate in the pipe during operation. There is a certain submerged depth.
