Submersible pumps are designed to be fully submerged into the water. They are placed within the reservoir of water that requires pumping out, which is why they are normally used for drainage in floods, sewerage pumping, emptying ponds or even as pond filters.
Submersible pumps are designed to be fully submerged into the water. They are placed within the reservoir of water that requires pumping out, which is why they are normally used for drainage in floods, sewerage pumping, emptying ponds or even as pond filters. In this article, we will specifically address a smaller model of the submersible pumps which are commonly referred to as the small submersible pumps.
A small submersible pump is the small version of a submersible pump that is lightweight, small sized, low consumption, and makes little noise. A small submersible water pump is used widely in households for cooking, cleaning, bathing, space heating, watering flowers, etc. A small submersible pump that is centrifugal utilizes a motor to power an impeller that is designed to rotate and push water outwards. The motor is located in a waterproof seal and closely connected to the body of the water pump which it powers. Filtration pumps found inside aquarium fish tanks utilize a type of small submersible water pump. The small submersible pump is installed inside the actual fish tank to pump the water out where it is needed. You will often see small submersible pumps installed in the basement.

Small submersible pumps have many uses, not just in the basement or fish tanks. Small submersible pumps can be widely seen in single homes, condos, etc. where every homeowner, condo owner and maintenance crews can take only a few minutes to set up one of these mini water pumps. Water damage from flooding can lead to thousands of dollars of loss in an extremely short amount of time, so it is important to stay vigilant and protect your property by installing a small submersible pump. Many single house owners have pools in the backyard, spa or other water features to use these small submersible pumps to clean the inside and unclog the pipes. As you may have noticed, small submersible pumps are more frequently used in household settings, whereas larger and stronger water pumps would be more commonly utilized in industrial and agricultural settings.

First and foremost, small submersible pumps are extremely lightweight as they typically weigh less than 20 lbs. You can even find models that weigh as low as 6 lbs. Another key advantage of a small submersible water pump is that it is very quiet since it is submerged into the water when run, and the water absorbs the noise. This makes for perfect household utilization because you will not hear a submersible water pump running even within a confined space. Small submersible pumps are very efficient as well because they do not require a lot of energy to vacuum in water within which they are submerged.
However, known disadvantages of small submersible water pumps are that seals tend to corrode over time which allows water to potentially seep into the motor. When this happens, the motor could be rendered useless, and accessing and repairing becomes extremely difficult.
Small submersible pumps are mostly deployed in household settings, and due to its size and weight, smaller motors are usually coupled with these water pumps. The motor is placed in a sealed case attached to the impeller, and is powered by a simple gear drive. At the center of the motor, there is a rotor with coils around it. Around those coils are the magnets, which create a lasting magnetic field that flows through the rotor. The rotor then acts on the magnetic force, allowing the rotor itself to spin around 180 degrees. As the rotor spins, the direction of the electricity in the coils flips, pushing the rotor again so that it spins the rest of the way around. Through several pushes, the rotor continues to spin and drive the impeller to power the pump.

Small submersible pumps are frequently seated at the bottom of water tanks, and are designed to push water upwards through the top of the roof. Given their water pumping mechanism, small submersible pumps are normally used in tanks where water needs to be pumped up to the surface.
If you happen to be installing a small submersible pump in an above ground tank, there are things you should consider: submersible pumps can be installed in an above ground tank, but you need to be mindful of the fact that rainwater may be plumbed in from the top. If you also wish to have direct access to the water in your dank, a tap can still be accommodated to your tank, or you may simply attempt to connect your rainwater to nearby taps.
Another thing to keep in mind is that having a small submersible pump in your water tank is the ease of accessibility in the event of maintenance or a replacement. It also tends to take up a small amount of space inside your water tank, but the downside is generally offset by the quiet nature of the pump.
There are a handful of things to consider when shopping for a small submersible pump. Here are the four most important factors:
When choosing a small submersible pump, you need to consider a few different types of pumps including pedestal, traditional, mini, etc. Each style has its pros and cons, so make sure to research on the best style for the intended job. For instance, you definitely do not want to drain a pool with a pedestal pump.
The horsepower of your water submersible pumps is always going to be one of the key factors when shopping for the best small submersible pumps. A small submersible pump, despite its size, can generate substantial horsepower if necessary based on the different styles and models. Be mindful of how much power you need because a motor too powerful will burn the engine, and you will not be able to drain water effectively with too little power.
Some small submersible pumps are made from plastic while others may be made of cast iron or stainless steel. Submersible pumps with plastic casings tend to be a little cheaper and lighter while the metal-bodied pumps have longer life.
This may sound a bit obscuring but you need to also consider the right size for your small submersible pumps. If you have limited storage space, you need to assess if the chosen small submersible pump will be able to fit in the intended area.
