Hayward KIT-DISC, DIAPHRAGM

the Hayward Diaphragm Disc Kit is a vital internal component designed specifically for the oscillating drive mechanism of suction-side automatic pool cleaners. Manufactured from a flexible yet resilient high-grade elastomer, this disc acts as the primary interface between the water flow and the mechanical pulse of the cleaner, facilitating the rapid opening and closing cycles required to move the unit across the pool floor. Its primary function is to maintain a consistent vacuum seal while providing the structural support necessary for the diaphragm to expand and contract without collapsing under high pump pressure. By absorbing the repetitive stress of the hydraulic pulse, the disc ensures a smooth, rhythmic movement that prevents the cleaner from stalling and helps it navigate over drains and uneven surfaces. Because it is constantly exposed to the friction of moving water and the chemical environment of the pool, it is engineered to resist tearing and chemical degradation. For shipping and logistical purposes, the estimated weight of the Hayward Diaphragm Disc Kit is approximately 0.25 pounds in its retail protective packaging, while the actual weight of the disc component itself is roughly 0.12 pounds.
