  • Clean the pump thoroughly with a soft cloth and warm water. Remove any debris or dirt that may have accumulated during use. Pay special attention to the impeller and the suction strainer.
  • Once the pump is clean, let it dry completely before storing it.

How does a submersible water pump work underwater?

How does a submersible water pump work underwater

When a submersible water pump is under the water, it operates like a fish in the sea. The pump’s impeller pulls water into the unit and generates the required pressure to move the water to the surface.

The pump begins by rotating the impeller, creating a low-pressure area. This low pressure encourages water to flow through the pump’s inlet and into the pump. As the water passes through the pump, it moves toward the impeller. When the impeller accelerates water, it exits with more pressure and force.

From here, the water flows through the diffuser, which directs the water toward the surface. The diffuser converts the kinetic energy of the water into pressure energy, allowing the water to move toward the surface.

What Are the Types of Submersible Pumps?

In terms of submersible pumps, there are several types to choose from:

Submersible Pure Water Pump

To get that crystal-clear water from your well, you’ll want to use a submersible pure water pump. This type of submersible pump is specifically designed to pump out clean water free from debris or contaminants.

It is commonly used for applications such as draining swimming pools or hot tubs, as well as pumping water from wells and cisterns. One of the key features of a submersible pure water pump is its ability to handle high volumes of water flow without clogging or overheating.

Submersible Pumps with a Valve

If you’re looking for a pump that can switch on and off automatically, you might consider one with a valve. This submersible pump is particularly useful when maintaining a certain water level, such as in a swimming pool or a pond.

With a valve-equipped pump, you can easily control the water flow and level without manually turning the pump on and off every time. Here are some features of submersible pumps with a valve that you should keep in mind when shopping for one:

  • Automatic on/off switch: A valve-equipped pump can automatically turn on and off based on the water level, which makes it more convenient to use and can save energy.
  • Pressure regulation: The valve can help regulate the pressure of the water flow, ensuring it stays within a safe and efficient range.
  • Easy maintenance: Because the valve controls the water flow, it can also help prevent clogs and other issues affecting the pump’s performance. This means you’ll have to spend less time and money on maintenance and repairs.

Submersible Pumps with Low-Intake

A low-intake submersible pump is an excellent option when the water level is not that high. The inlet of this type of pump is situated very close to the ground, allowing it to suck up water at the bottom of the pump.

When using a low-intake submersible pump, it must be placed on a flat and stable surface to prevent it from tipping over. Moreover, you should avoid running the pump dry to prevent damage to the motor.

Always ensure the water pump is fully submerged in water to avoid overheating. Also, it’s crucial to clean the pump regularly, especially if it’s used in dirty or muddy water.

High-Pressure Submersible Pump

You can feel the power of the high-pressure submersible pump as it blasts away dirt and grime from your home’s siding, leaving it sparkling clean. Homeowners in rural areas could use this pump to clean their exteriors without needing a high-pressure system.

Here are some things to keep in mind when using a high-pressure submersible pump:

  • Make sure the pump is entirely submerged in water.
  • Use a high-pressure hose and spray nozzle to direct the water where you want it to go.
  • Keep a safe distance from the pump to avoid getting sprayed with water.
  • Wear appropriate safety gear, such as goggles and gloves, to protect yourself from debris and water.

What to Consider When Choosing a Submersible Pump to Water Out?

What to Consider When Choosing a Submersible Pump to Water Out

When choosing a submersible water pump to water out, several factors must be considered to ensure you choose the right pump for the job.

Depth of Water

Knowing the depth of the water is crucial when using a submersible pump, as it’ll determine the appropriate pump size and prevent damage to the pump. Here are some important things to consider when determining the depth of the water:

  • Measure the water depth accurately using a measuring tape or a depth finder.
  • Check the manufacturer’s specifications to ensure the pump fits the water depth.
  • Choose a pump with a maximum pumping depth greater than the depth of the water to be pumped.
  • Consider the distance between the water pump and the water source, as it’ll affect its performance.

Pumping Lift

As you lower the hose into the water, imagine the pump lifting the water through the hose and out of the nozzle. This vertical distance between the water pump and the highest discharge point is called the pumping lift.

The pumping lift is one of the most important factors determining your submersible pump’s performance. This is because the higher the pumping lift, the more work the pump has to do to move the water.

To determine the pumping lift of your submersible pump, measure the vertical distance from the water surface to the highest point of discharge. The pumping lift and the depth of water will determine your pump’s total dynamic head (TDH).

Required Volume

To ensure you have enough water, calculate the required volume by considering the number of people using the water, the length of time they will use it, and any additional water usage requirements. Here’s how:

  • Determine the number of users using the water. This helps estimate how much water is needed per person.
  • Calculate the length of time the water will be used. This helps determine the total amount of water needed.
  • Consider additional water usage requirements, such as watering plants or filling a swimming pool.

Power Source

You’ll need a reliable power source to keep your submersible pump running smoothly. There are a few options to consider, but the most common ones are electricity from the grid, a generator, or solar power.

Electricity from the grid is the most convenient option, as it’s readily available in most areas. However, ensure that your electrical system can handle the power requirements of your pump.

Water Cleanliness

Ensuring the cleanliness of your water source is crucial for maintaining the efficiency and longevity of your submersible pump system. Before installing the pump, it’s important to check the water quality.

Any debris, sediment, or other contaminants can clog the pump or damage its components. This can result in reduced water flow, increased energy consumption, and even complete system failure.

To prevent this, installing a filter or strainer between the pump and the water source is recommended. This will help trap any debris or sediment before it enters the pump.

Can I use a submersible pump to empty a hot tub or swim spa?

Can I use a submersible pump to empty a hot tub or swim spa

You can use a submersible pump to drain your hot tub or swim spa. In fact, it’s a quick and efficient method that can save you a lot of time compared to using drain valves. But before starting, ensure the hot tub or swim spa is turned off. Connect the submersible pump to a suitable extension lead and have everything organized.

Once your setup is ready, carefully submerge the pump, ensuring it’s fully underwater. Then, switch on the pump at the wall outlet to begin the drainage process. As the water level drops, the float switch will detect the change and automatically stop the pump to prevent it from running dry.

Do I need a water tank with a submersible pump?

When supplying a household with water, pair a pressure tank with a submersible pump for reliable and consistent high pressure. With a pressure tank, a submersible pump will maintain the desired pressure range of 45-60 psi required by a household.

Moreover, a pressure tank helps to reduce water hammer, a deafening banging noise that occurs when a valve closes abruptly. Water hammers can harm pipes, valves, and even the pump itself. By absorbing the water hammer shock, a pressure tank helps prevent system damage.

Apart from regulating water pressure and reducing water hammer, a pressure tank also prolongs the submersible pump’s lifespan. A pressure tank reduces wear and tear on the pump by reducing the number of times it turns on and off, allowing it to last longer.

Can I run a submersible pump without a control box?

If you’re wondering whether you can run a submersible pump with no control box, the answer depends on the type of pump you have. Two-wire pumps don’t require a control box, but three-wire pumps do.

For three-wire pumps, a control box is necessary as it contains the starting circuits for the pump. Without it, the pump won’t work properly as it won’t receive the necessary signals to start and stop. Not only that, but a control box also protects the pump from electrical damage.

Installation of a control box is straightforward and often done outside near the well. They are designed to withstand tough outdoor conditions and are typically weatherproof.

To ensure proper installation and usage, always follow the manufacturer’s instructions. Using a control box, your submersible pump will work efficiently and have a longer lifespan.
