Pentair 26" Sand Dollar® Top Mount Filter SD80 with 1.5" MPV

Pentair Sand Dollar® 26" Top Mount Pool Filter SD80 with 1.5" MPV

The Pentair Sand Dollar® SD80 is a heavy-duty, high-capacity 26-inch top-mount sand filtration system meticulously engineered to deliver exceptional water clarity for large residential swimming pools. Utilizing a unique, patented molding process, the filter body is constructed as a seamless, one-piece thermoplastic tank that provides incredible structural strength, total corrosion resistance, and an extended operational lifespan capable of enduring punishing UV exposure and aggressive water chemistry. This specific model features a clamp-style, 1.5-inch six-position multiport valve (MPV) that mounts to the top of the tank, granting pool owners effortless manual control over vital hydraulic pathways—including filter, backwash, rinse, waste, closed, and recirculate—with a single, user-friendly lever. Internally, the SD80 is outfitted with a specialized lateral grid design and an integrated water diffuser that distributes water evenly over its expansive 3.5 square feet of effective filtration area, keeping the internal sand bed perfectly level to maximize debris-trapping efficiency and prolong the intervals between required backwashing. It comfortably manages a robust design flow rate of up to 75 gallons per minute (GPM) at a maximum operating pressure of 50 PSI, making it an excellent match for high-performance, energy-efficient pool pumps. Servicing and seasonal maintenance are further streamlined by an integrated manual air relief valve, an easy-to-read pressure gauge, and a specialized combination sand-and-water drain located at the base of the vessel. The dry weight of the Pentair Sand Dollar SD80 filter tank body including its 1.5-inch multiport valve assembly is approximately 44 pounds (noting that full operational deployment requires an additional 350 pounds of standard pool silica sand), offering a highly reliable, low-maintenance centerpiece for large-scale aquatic filtration pads.
