A submersible water pump is a pump that can be fully submerged in water. It’s a good water pump capable of drawing water directly from the source, either river or pond. It’s just a suitable pump. Mostly, it’s preferred for irrigation by farmers or those transferring water. This article focuses on submersible pumps and the factors to consider when buying them.
We all believe water is life. Having a borehole with a submersible pump with clean water is a nice thought that will help you save time and money. Furthermore, it generates income for an individual because those in the neighborhood who can’t own their water pumps will find themselves purchasing water from you.
However, before purchasing a submersible, you’ll have to check the models, the brand, and other pertinent factors depending on your intended usage. Nevertheless, in this article, I bring to your attention a perfect guide on such considerable factors before purchasing a submersible water pump, and I believe you’ll get to learn something pleasing from it.
- Type of Water
When shopping for a submersible pump, the kind of water you’ll be pumping is a significant thing to keep in mind. The specifications of submersible water pumps change based on your location and the type of water:
- Submersible Pumps for Clean Water
If you’re planning to collect clear water such as rainwater and pump it for keeping, then a thin submersible pump with a maximum gain width of less than 5mm is the best choice.
- Submersible Pump for Dirty Water
Suppose the water you’re looking forward to pumping has alot of dirt, then you require a perfect pump to operate in such dirty waters. The pump must function correctly even in dirt and muddy waters. Such pumps are used to empty septic systems and sewage. The recommended gain diameter for dirty waters is about 15mm.
- Submersible Pumps for Wells.
These primarily draw water from domestic plumbing systems. You must consider the depth of your wells and get the right pump.
- The Cost of the Submersible Pump
The price of a submersible pump depends on several factors. One such factor is the operating capability of your intended pump. Pumps that are more powerful and have full heads are always more expensive than those with smaller heads. The submersible pump price in Kenya is an essential factor to consider.
- Float and Flow Switch
The float switch controls the pump depending on the level of water. In many cases, it stops pumping if water is not available. Moreover, it switches the pump off, preventing any damage caused by the submersible when the water level goes down.
A flow switch regulates how water flows through the pump at a given time. Submersible smaller pumps typically use vertical controls, whose diameter is 10 inches, while tethered switches are typically used in activating the pump, whose width is 14 inches.
- Discharge Height
It determines the water pumped by the submersible in an hour or minute. It’s the power level of the pump. A power level of about 400 per hour is highly recommended for individuals intending to draw water from a barrel. A discharge rate of about 1.5 gallons per hour is preferred for those wishing to draw water on a basement level.
- Backup System
Submersible pumps are typically powered using electrical voltages. Therefore, it is advisable to choose a pump with a power backup. This factor will aid in avoiding severe damage. A battery-powered pump is better because it provides power, which lasts longer during contingency situations.
- Cooling System
The motors of submersibles usually are either filled with water or oil. For engines that are water-filled, water acts as a coolant, hence repeatedly filled. However, the oil-filled motors have no coolant. The motor’s chances of searing, tearing, and damaging are high. The water-filled engines are expensive, though.
- Suction Depth
Water may not fully cover the suction assembly in certain situations. It enables entry of air and may stop the pump from operating. You should check the water level for which the pump works.
In summary, submerged water pumps are better compared to external ones. They last for longer due to minor mechanical issues. They are more efficient as the water pressure aids in moving the fluid into the pump; thus, they require little energy. The above-discussed factors will help you choose the best one to meet your needs satisfactorily.
