What is a submersible pump and why use one?

Since the dawn of human civilization, people had to find and use underground water for hygiene, agriculture and other purposes. Sure, sometimes you can use the water from lakes and rivers and even the rain, but most of the time, if you need a constant source of water, you’ll have to pump it out of the ground. While cities have different types of water supplying, which doesn’t require effort from the part of the people buying apartments in the town center, if you intend to move in a more rural area or even the suburbs, you need to think about buying a pump. If you install a pump on your land, you will be able to access the phreatic water sources and have a constant supply of water. You won’t have to worry about water shortages, but you will have to invest time and money in a submersible pump, which is not an easy task and not especially cheap, but if you choose the right pump, you’ll be secured for years to come. A submersible pump can be used in a variety of ways and has multiple uses around the house. Pumps can be used to pump water out of areas where water is not desirable, like the basement. If you had a flooded basement, you know how annoying and dangerous it is to have one. Using a submersible pump you can take the water out very quickly and some of them can pump out even solids. Other pumps can be used on a more regular basis for sewage work and just by buying a good pump you can build a decent water system without having to connect to the public system. Submersible pumps are complex devices, but the working principles are the same for many, many years. Basically, a submersible pump is a cylinder that is usually between 2 and 4 feet long and a maximum of 5 inches in diameter. Maybe it doesn’t sound too impressive in terms of specs, but the device can accommodate a debit big enough to satisfy the needs of a medium sized household. While over ground pumps literally suck the water out of the ground, submersible pumps push up the water, as these pumps are submerged (hence the name) into the liquid that has to be pushed out. Inside the pump, there’s a hermetically enclosed motor, which makes the entire pump function. Of course, the motor has to be sealed so that it doesn’t get in contact with the liquid and thus produce a short circuit. Besides the motor, there’s a cable that connects to the motor and the actual tube used to push the liquid out. When the pumped is powered, the motor determines some impellers to start working and the liquid is pushed up the tube. These impellers turn at very high speeds, determining a constant flow of water upwards. In comparison with surface pumps, a submersible pump has the advantage that it may malfunction rarer. Surface pumps can break easier due to an issue called cavitation, whereas submersible pumps don’t have this issue. Actually, a submersible pump can last for much longer, as the average life of one of these devices is 25 years. That’s a pretty good deal, considering the support one of these pumps can deliver for any household.
