Bestway sand pump, essential for cleaning your pool water! It is used to recycle and clean the water of your pool from various pollutants such as dirt, sand, leaves, insects, and various particles, with a separate filter that helps in disinfection and preventing the growth of algae and mud on the walls. The water is pumped from the pool, passes through a filter, and flows back into it, free from the residues it has retained. Recommended for pools of 1,100-33,300 L, as the flow of the system filters 7,571 L per hour.
