A fountain pump is such a pumping device, which has outstanding efficiency to supply water to the fountain fixtures based on the circulation techniques.

This kind of pump meets the needs to supply water flow for aesthetic purposes, residential and commercial aeration.

The configuration of this pump provides the best water movement service to the indoors or outdoor fixtures.
The differentiation of the size of this pump depends on the size of the pond or pool and the type of applications, which can be functional or decorative.

How To Decide The Sizing of A Fountain Pump?

While you plan to bring an efficient fountain pump, you should focus on the particular matter, which in its design.

You will get so many models of submersible fountain pumps with compact designs in the market. But how will you recognize the suitable one?

The answer to this easy doubt lies in the quantity of water you need to lift within a specific time.

In general conditions, a small fountain requires the simple submersible technology run pump, which is efficient enough to recirculate almost 50 gallons per hour.


But it would help if you considered your plan to recirculate water for more giant fountains or artificial waterfalls.

Because this kind of operation always requires a robust mechanism-based submersible fountain pump.


So, the following discussion shows how you can decide the sizing element while buying a compatible fountain pump.

❖ Firstly, it will be better to adequately determine the maximum rating of head height and the maximum range of lifting.
❖ Then use a measuring tape to calculate the fountain spout diameter. Following this trick, you can estimate the capability of gallons in a single hour and calculate GPH by multiplying the range of diameter by 100.

For instance, if your fountain spout diameter range is 1 inch, then the GPH rate of your pump will be 1 x 100 = 100 GPH.


❖ Now, you need to check the total height between the fountain pumping unit and the fountain spout.

This measurement will help you to determine the maximum range of fountainhead height.

The rating of this head height defines if the pump will lift the water to the fountainhead.
This measurement has a striking difference with ‘pumping height‘, which defines the measurement from the pump outlet port to the top of the water height.
❖ Now, take a look at the package of specifications of the pump unit package for a fountain.

Suppose you have the following mentioned specifications within a pump equipment package:

Type of pump:Submersible
Pump GPH:170
Maximum Lift :49.0 (inches)
Horsepower :(0.01)
CSA Safety Inclusion:Yes
Warranty:2 years

❖ You should select such a pump having the required head height to provide overall optimized performance.

Suppose you have a fountain that is almost 30 inches tall. You need to find such a compatible fountain pump unit, which has a maximum range of lifting of 45 inches even more.

Selection of the maximum head height based pump, which is taller than the fountain, always provides a good water flow in the fountain.
You will always get the option to reduce flow as per requirements. But for the increment of water flow, you always need a pumping unit with a higher rating.

Here, you will get a few recommendations on proper tubing size.

Because this matter also influences the maximum ranges of lifting capability of your pump.

If you opt for a smaller tubing size than the recommended limit of water circulation, you will get less range of maximum lift.

What Is The Specific Working Principle of A Fountain Pump?

The structural pattern of the fountain pump ensures flawless performance utilizing the positive displacement force.

All the pumps you can deploy to lift the water for your fountain are categorized as Dynamic pumps.

And sometimes, these pumps depend on velocity and fluid momentum using centrifugal force to boost the pump pressure.

As well as the core principle of concentrating cavities and expansion involves a positive displacement technique also for moving the water.

Having the capability to produce a wide range of flow, a dynamic pump creates a high flow rate.

Fountain pumps are centrifugal as it creates pressure to move water using centrifugal force involving an impeller.

In terms of functionality, a fountain pump is quite similar to a sump pump. The difference lies in the feeding back of the water into the reservoir or pond.

The pumping unit sends the water to a fountain device that sprays water on the surface.
While the water droplets return to the surface, they collect oxygen.

Thus a fountain pump executes the microbial action or supplies oxygen to the farming tanks or fishes in the ponds.

Know About The Type of Fountain Pumps

This pump can be categorized into submersible or external types depending on the type of operations and applications.

❖ The submersible unit of this pump has an attached motor with a body along with an airtight seal.

So, the overall structure of this pump allows th]e pumping unit to be submerged under the source of water.

This kind of pumping unit has multiple flexible options to install and run the operations at low expense.
❖ The external type of this pump has specific requirements for installation. But this type of pump is efficient enough to run operations in larger reservoirs or ponds.

The great advantage of the external fountain pump lies in its lower operating costs. Generally, external pumps provide flawless performance to deal with backpressure.

The involvement of external filters makes the performance more efficient.

Get Some Details About Applications of A Fountain Pump

Depending on its particular applications, this pump has two variants. One is industrial, and another is commercial.

● To meet the purpose of decorations, you have to install a commercial fountain pump. So, the commercial models of this pump come in a wide range of varieties.

Indoor and outdoor pumps belong to the commercial family, and garden fountains are also a decorative type of fountain pump.

In the cases of decorative models of this pump, the reservoir or sump on the ground contains the specific fountain machinery.

Here, the following discussion represents the difference between indoor and outdoor pumps.

❖ To operate the decorative devices and indoor fountains, you need indoor pumps. This type of pumping unit comes with a low flow rate.
❖ While you need to move a more significant amount of water in a single hour than an indoor fountain, you have to install an outdoor pumping unit.

In these cases, the operations need outdoor fountain machinery for beautification. And these pumps also need aeration pools and ponds for aeration.

● For different purposes, including treating sewage, aeration of wastewater in the manufacturing fields, treatment of water for municipality usage, you need an industrial fountain pump, and industrial models of this pump circulate the stagnant water to prevent the algae generation and mosquito population.

In comparison with consumer versions, the industrial models provide rugged performances.

So, naturally, this type of pumping unit always comes with a robust structure to generate higher pressure and flow rates for different kinds of media.

All the points discussed here present essential information to guide you to select the compatible fountain pumps as per your requirements.
