A submersible pump is a device that has a hermetically sealed motor that is closely connected to the pump body. The entire assembly is immersed in the fluid to be pumped. The main advantage of this type of pump is that it prevents pump cavitation, a problem associated with a large height difference between the pump and the liquid surface.

What are the commissioning steps for the submersible pump?
submersible pumps under 11 kW may start directly. submersible pumps over 13 kW should be equipped with a vacuum start-up cabinet. To protect the safe operation of submersible pumps.
2.To prevent sudden jump up of the rotor of the submersible pump and reduce the start-up load. When the submersible pump is started, the outlet valve stroke should be closed to 3/4. (Leave a 1/4 air gap for emptying) Open it slowly after starting the water. For this purpose, the pump operating point is adjusted to a suitable position.
3.After the startup process is completed, the operation begins. Monitoring and monitoring of water level changes should be strengthened. Make sure the submersible pump works within the operating conditions. After the submersible pump runs smoothly, it can be formally put into operation.
4.5 hours after initial commissioning of the submersible pump. The thermal insulation resistance is measured quickly when the machine is switched off. Its value is no less than 0.5 MΩ. to continue to use.
How does a submersible pump work?
A submersible pump is a device that pumps water from a well or other body of water to the surface. The pump is driven by an electric motor. The motor rotates a impeller that draws water from the well and pushes it to the surface.
How to choose a submersible pump?
When choosing a submersible pump, there are many factors to consider, such as the intended use, the desired flow rate, the required immersion depth and more.
The first step is to determine the intended use of the pump. submersible pumps can be used for a variety of applications including wastewater treatment, water supply, irrigation and more.
Next, you need to determine the desired flow rate. The flow rate is the amount of liquid that the pump can move per unit of time and is usually measured in gallons per minute (GPM).
Once you know the intended use and desired flow rate, you can narrow your selection by considering other important factors such as the required immersion depth and power source.
The required immersion depth is important because it determines how deep the pump can work underwater. Some pumps can be used immersed in water up to 100-foot deep, while others may only be suitable for shallow depths.
Finally, you need to consider the power source for the pump. submersible pumps can be driven by either an electric motor or a gas motor. Each has its own advantages and disadvantages, which should be considered before making a decision.
