Recirculation pumps are a very important element in fountains and allow the recirculation of the water contained, keeping it in perfect physical and chemical conditions.
What is a recirculation pump?
The main purpose of a recirculation pump is to guarantee the correct quality of the fountain’s water at all times, with a view to removing solid objects from the water and keeping it in perfect chemical conditions.
To determine the size of a recirculation pump you need to know the volume of water in the fountain it is to be installed in.
Normally non-controlled pumps are used, as there is relatively little variation in the flow. However, in larger systems, it may be better to use controlled pumps to adjust the flow when the system starts up and control the chemical parameters.
The pumps OTB uses in its installations are an excellent option for recirculation pumps for water treatment systems. These pumps are designed specifically to ensure a constant, efficient flow of water, providing convenience and energy savings in recirculation systems.
How do you choose the right recirculation pump?
There are a wide range of recirculation pumps. Each type of ornamental fountain has its own characteristics and considerations, so the choice of the type of recirculation pump will depend on the specific requirements and needs of the fountain in question. Some factors to take into account in selecting the type include:
- Size and complexity of the fountain: Ornamental fountains can vary in size and complexity. Some fountains are small with a small volume, whilst others may be very large with more advanced technical characteristics. The type of pump should be suitable for the size and complexity of the fountain to guarantee its correct functioning.
- Availability of space: The space available for the installation of the recirculation pump may affect the type of pump chosen. Some types of installation may require more space for equipment and systems leading to the need to install submersible recirculation pumps, whilst others may be more compact and suitable for limited space.
- Type of fountain: The recirculation of the water is a very important factor to take into account in fountains and depends on the type of fountain installed. Some fountains may require greater recirculation with the same volume to be treated as others due to their type, which means more intensive water treatment is necessary. The choice will depend on the design of the fountain and the location, as well as the efficiency and maintenance requirements.
It is essential to assess all these factors and consult with experts in hydraulic engineering and ornamental fountain design to make an informed decision regarding the most appropriate type of installation for each specific project.
What does the recirculation pump do in an ornamental fountain?
As they are closed circuits, ornamental fountains constantly reuse the water contained in their systems. As this water is exposed to the environment, it requires a water treatment system to maintain its sensory properties in terms of control, colour, turbidity, conductivity, pH and presence of microorganisms.
Recirculation pumps allow all the water in the fountain to be correctly treated through a filtration and chemical product dosing system to keep it in optimum conditions.
