Water Circulating Pump – Efficient Pool Water Circulation

Water circulating pumps are the core components of the swimming pool water treatment system. Their main function is to drive water flow through the filtration system for filtering and disinfection, and then return the treated water back to the pool, ensuring clean and hygienic water quality while maintaining a constant water temperature. Specific functions include:

Water circulation: The pool circulating pump draws water from the pool and pushes it to the filtration system, achieving water circulation. This ensures even distribution of water quality and prevents the formation of dead zones.
Water filtration: The pool circulating pump sends water to the filter, where filter media (such as sand or cartridges) remove suspended particles, contaminants, and microorganisms. This makes the water clear and transparent, reducing harmful substances in the water.
Chemical distribution: The pool circulating pump can evenly distribute chemicals (such as disinfectants and pH adjusters) into the pool water to maintain sanitary and balanced water quality.

Key Factors to Consider When Choosing a Pool Pump

Flow Rate

The flow rate determines the amount of water the pump delivers per unit time. The larger the pool, the more it requires a high-speed driven pump to ensure sufficient water circulation.

Energy Efficiency

Choosing an energy-efficient pool pump can significantly save on energy costs in the long run. For example, pool pumps with variable speed adjustment and programmable timer functions.

Noise Level

Consider the noise level of the pool pump, especially if your swimming pool is located near a residential area. It is recommended to choose a low-noise, high-efficiency pool pump to avoid noise disturbances.

Durability

Pool pumps made of high-quality materials with stable and reliable electrodes have exceptional durability, are easy to maintain, and have a longer service life.

Structure & Working Principle

Aside from the inlet and outlet, a pool water circulating pump mainly includes the following components:

HOUSING: Contains the strainer basket and has a clear lid to allow inspection of the basket. Water is pulled into the housing and through the basket by the pump's impeller. Large dirt and debris are captured in the strainer.
IMPELLER: High-speed rotating vanes pull the water into the pump though the inlet and force it through the outlet.
DRIVE: On variable speed pool pumps, the drive allows the pump to run at varying speeds. It also acts as the interface to program schedules and other settings.
MOTOR: The motor is attached to the back of the pump housing. Its sole purpose is to spin the impeller.

In summary, the working principle of the pool water circulating pump is that it draws pool water through the inlet, then, driven by the impeller and motor within the pump, pushes the water out at high speed. The expelled water flows through the filtration system, where filter media remove impurities and contaminants from the water. The cleaned water then recirculates back into the pool, maintaining continuous water circulation.
