1. Manual and electric dual-purpose type.
Add a tee to the pumping pipe below the hydraulic well and connect it with a self-priming pump. When pumping water electrically, it needs to be lifted manually, or two valves can be added, manually or electrically, and the valves can be switched.
As for the self-priming pump, you can choose the screw self-priming pump, which has large suction and high lift.
This kind of self-priming pump can be used with pressure storage tank, and the normal pressure can reach 3㎏, even for a three-story building.
There is also a self-priming pump with its own pressure controller, which automatically starts when water is used after power is connected, and automatically stops when there is no water, which is also very convenient to use!
Second, pure electric pumping.
If only electricity is used as the power to pump water, the hydraulic wellhead is useless. Just use the self-priming pump to ground the sewer pipe directly.
There is also a kind of equipment commonly known as wire drawing well, which is more efficient than self-priming pump.
The wire drawing well is provided with a tripod, an upper motor and a lower pumping spiral wire drawing, and the wire drawing well penetrates into an underground water pipe. When working, the motor rotates at high speed for wire drawing, and water is continuously pumped out.
Drilling wells is very common in areas with deep groundwater level. At a depth of 30 meters, the self-priming pump can do nothing, while the water pump can do it easily.
