Three Important Elements to Consider for Submersible Pump Selection

If you are looking for an ideal pump to draw water from your borehole, well or storage tank, you should think about acquiring a submersible pump. As suggested, this type of pump is designed to be submerged or immersed into the pertinent containment of water. They are highly efficient because they do not require priming, unlike alternatives which are not in contact with water. On the other hand, the quality of submersible pumps in the modern market is different, so the performance after installation can vary significantly. Therefore, consider these important elements when choosing a submersible pump for your home.

Construction Material

In general, submersible water pumps are manufactured using stainless steel. This material is favoured in the fabrication because it is strong and resistant to mechanical damage. In addition, this alloy steel contains considerable amounts of chromium which retards corrosion and rusting. You should, however, note that there are different grades of stainless steel, and this can affect the long-term functionality. Typically, if your water quality is good and free of contaminants, standard stainless steel, which is technically known as grade 304, is sufficient. However, if your water source is relatively saline or contains corrosive elements, you should consider marine grade steel.

Discharge Rate

The discharge rate is an important value which will help you understand the power and capability of the submersible pump. This can be defined as the volume of water that the pump can handle within specific unit time. You must evaluate your application and its requirements and compare with the specifications of your preferred pump before making your purchase. For example, if you would like a pump for agricultural applications, you will require high discharge rate for efficient irrigation and animal watering. On the other hand, if the water is intended for general domestic use, a low-power pump will accomplish its purpose. Remember that a higher than necessary discharge rate means that you will have unnecessary expenses while a lower rate could lead to premature pump failure.

Float Switch

The float switch is a critical feature if you are pumping water from a tank or the level of water in your well or borehole tends to shift. This is a special element incorporated into some submersible pump to prevent the device from operating if the water level falls below it. The switch ensures that the pump is automatically turned off, preventing the internal components from sustaining. If you choose a pump with this feature, you should ensure that the multiple beneficial settings and adjustments.
