What are the two main types of pumps used in aquatic facilities?

The two main types of pumps used in aquatic facilities are centrifugal and positive displacement pumps. Centrifugal pumps work by using a rotating impeller to add velocity to the water, converting kinetic energy into flow. This type of pump is effective for moving large volumes of water and is commonly used in circulation systems in pools and aquariums.

Positive displacement pumps, on the other hand, operate by trapping a fixed amount of water and forcing it through the discharge. This type is ideal for applications requiring precise flow rates, such as dosing chemicals in a treatment system or when a consistent flow is essential.

Understanding these two types of pumps is crucial for aquatic facility operators, as they each have specific applications, advantages, and operational characteristics that influence their use in maintaining water quality and efficiency in aquatic environments.
