High flow suction / delivery nozzle for liner pools

Swimming pool nozzles

Suction and impulsion nozzles are key components in the hydraulic system of swimming pools. They allow efficient water circulation, ensuring cleanliness by facilitating suction into the filtration system and uniform distribution of treated water. In addition, they contribute to the homogeneous mixing of chemicals and prevent stagnation zones, keeping the water clean and in motion. Their design ensures optimal operation for a healthy and crystal clear pool.

The suction and impulsion nozzles are essential for an efficient recirculation circuit, which not only guarantees the cleanliness and quality of the water, but also provides significant savings in maintenance time, chemical consumption, and energy for water conservation and heating.

Pool suction nozzle function

The suction nozzle is a component of the pool hydraulic system that allows water to enter from the pool to the filtration system. Its main function is to collect the water to be cleaned, removing impurities and contaminants before returning it to the pool.

In most pools, especially residentialpools , a sump is used instead of suction nozzles. However, if suction nozzles are chosen, their number should be determined by the maximum flow rate allowed by the nozzles, the diameter of the pipes, and the capacity of the pump. This ensures an efficient and adequate flow to the filtration system.

Pool delivery nozzle function

The impulsion nozzle allows the exit of the filtered and treated water into the pool. Its main function is to distribute the water uniformly, ensuring an efficient circulation and favoring the homogeneous mixing of chemical products, which contributes to maintain the quality of the water.

The number and location of the impulsion nozzles are determined according to the shape of the pool and its specific characteristics. They are strategically placed to direct the water towards the skimmers and ensure an efficient flow. For example, in a pool with a Roman staircase, one nozzle may be installed on the staircase and two additional nozzles on the sides to direct the water to the end where the skimmers are located.

The discharge nozzles should be installed 15 cm below the water level, ensuring an effective flow and avoiding splashing or operating problems.
