A mini submersible pump is a smaller version of the submersible water pumps which is lightweight and small size,it is used widely in household for cooking, cleaning and watering flowers. In this article, we'll show you how it work.

 

Mini Submersible Pump Overview

Submersible pumps in general are designed to be fully submerged into the water. Submersible pumps 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, the mechanism of a smaller type of submersible water pump called the mini submersible pump will be specifically addressed.

A mini submersible pump is a smaller version of the submersible water pumps which is lightweight, small size, low consumption, and makes little noise. A mini submersible water pump is used widely in household for cooking, cleaning, bathing, space heating, watering flowers, etc.

A mini submersible water pump is a centrifugal water pump, which means that it uses 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 mini submersible water pump. The mini submersible water pump is installed inside the actual fish tank to pump the water out where it is needed.

 

Advantage and Disadvantage of Mini Submersible Pump

Other than being small and lightweight, a key advantage of a mini 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.

Min submersible water 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 mini submersible water pump 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.

 

How the Impeller Works?

As stated above, a mini submersible water pump is a centrifugal water pump that employs both a motor and an impeller for the water pumping process. During the water pumping, the impeller spins very fast. The curved blades channel water into the eye, or the center of the impeller, and the water flows along the outer part of the blades.

Due to the fast movement of impeller, the centrifugal force compresses the water against the outer part of the blade. The pressure then causes the water to jet forward in a high speed manner out of the impeller. This resulted speed generates pressure on the outlet side of the pump, pushing the water through the pip.

How Does the Motor Work?

As previously mentioned, mini submersible water pumps are mostly deployed in household settings, and due to its size and weight, smaller DC motors are usually coupled with these water pumps. The DC 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 they pump.

 

Using a Mini Submersible Pump in a Tank

Mini submersible water 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, mini submersible water pumps are normally used in tanks where water needs to be pumped up to the surface.

If you happen to be installing a mini submersible water 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 of 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 mini submersible water 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.
