What is a Submersible Pump?

What is a submersible pump

Check Price Here

A submersible pump is a water pump with a sealed and air-tight motor, which allows the pump to be fully submerged in water. The motor is also close coupled to the body of the pump, meaning that they are fixed close together as one unit. This makes the unit compact and ideal for a variety of applications which require the pump to be submerged in water.

Submersible pumps are designed to be placed within a reservoir of water that needs to be pumped out, making them ideal for drainage in floods, emptying ponds, sewerage pumping or even as pond filters.

Most submersible pumps work automatically and don’t require monitoring however this depends on the model.

Pros of Submersible Pumps

Submersible pumps have many benefits that make them an excellent choice compared to other types of pumps. These advantages include:

  • Higher efficiency – these pumps require a lower level of energy but are able to work very efficiently, maximizing the energy used. They also work quickly with great power.
  • No need for priming – we’ll talk about this in the section below, but this basically means the pump requires less maintenance. This also makes the process more automatic.
  • Quiet operation – because submersible pumps are submerged, they tend to work quietly. This makes them less annoying to use.
  • Prevents pump cavitation – this is a technical feature of submersible pumps, which we explain below. This enhances the durability of submersible pumps.
  • Automatic – most submersible pumps work on their own, with no need for monitoring. This makes them convenient to use as you don’t have to worry about the water running dry and the system burning out.

How Do Submersible Pumps Work?

Submersible pumps work in a straightforward way. The first step in the process begins with the water pulled into the pump, when the rotation of the impeller pushes water through the diffuser. Then, it pushes it with full force to the surface. It does all this by converting rotary energy into kinetic energy and then into pressure energy.

The main advantage of submersible pumps is that it prevents pump cavitation. If you’ve never heard of that before, pump cavitation is the formation of cavities or bubbles in liquid, which develop in areas of low pressure around the impeller of the pump. These bubbles can implode or collapse, triggering intense shockwaves inside the pump and causing significant damage to its housing as well as the impeller.

Another plus point of submersible pumps is that you’ll never need to prime it since the whole unit is submerged under water. These pumps are also highly efficient since they don’t spend a lot of energy to move water into the pump. The pressure of the water pushes it into the pump which saves a lot of its energy.

Submersible Well Pumps vs. Jet Pumps (a.k.a Shallow Well Pumps)

Jet pumps are more traditional, dated pumps. While they are useful, they’re not as efficient as submersible pumps. The main difference between these two types of pumps is that jet pumps draw the water out of the well, whereas submersible pumps pushes it out.

Location

One of the most obvious differences between these two types of pumps is where they are installed. A jet pump is located outside the well, usually on high ground, as this provides proper sucking capacity whereas a submersible pump goes directly into the well or water source, and sits at the bottom, entirely submerged in the water.

Deep or Shallow Wells

Jet pumps are both ‘deep well’ and ‘convertible’ meaning that they can be used for either a shallow well or to pull water from a deep well. A jet pump works for wells from 25 to 200 feet. A submersible pump can pull water from depths of 25 to 400 feet.

Performance

When it comes to the performance of these two pumps, submersible models tend to perform better than jet pumps and they don’t require any priming since they’re already under the water and ready to go. Jet pumps on the other hand rely heavily on priming which means that they need to fill up with water before starting to flow. This means that the pumping process of a jet pump will be much slower than that of a submersible one as well as the capacity, pressure and flow rate.

Energy Consumption

When it comes to the energy consumption of both pumps, you’ll find that they both use about the same kind of power. However, the way they use it is different. 

Submersible pumps don’t suck water in. Instead, they push it up which is a more efficient, flow-oriented and pressure-boosting process that allows for easy pumping. Therefore, they use the same power as a jet pump but in a way that produces better water delivery.

Jet pumps have to fight against gravity and the atmospheric pressure so they’re not as efficient.

Durability

Submersible pumps also provide higher durability because they use leak-proof gasket seals which prevent leaks, so you don’t need to worry about any electrical or other water-related issues. On the downside, though, they are more challenging when they need to be repaired but since they’re so well-made, they rarely break and don’t need any maintenance, lasting from 10 – 20 years.

Jet pumps, however, are more susceptible to cavitation, the result being that the water inside gets bubbles and the machine gets blocked. They also need to be constantly maintained which includes oiling as well. These normally last from 5-19 years.

Price

And now, moving on to the cost factor of these pumps. Here, the jet pump scores one over the submersible pump since it’s less expensive. However, installation can be costly and they need regular maintenance. The cost can add up over time and you may realize that you’ve paid more for maintenance than you did for the pump itself.

Submersible pumps are more complicated machines that need submersible builds and can be quite expensive but they require very little to no maintenance, so you won’t have to spend extra on that.

The Bottom Line

Submersible pumps have many applications and are ideal for use around the house or for your private well. Although they can be more expensive than most other types of pumps, submersible pumps are highly efficient, convenient and durable making them a worthwhile investment.
