Pentair 60 SqFt PLD Series System: 3 Modular D.E. Filter

Pentair Sta-Rite® System:3® S7MD60 / PLD Series 60 Sq. Ft. Modular D.E. Filter

The Pentair Sta-Rite® System:3® S7MD60 (PLD Series) 60 Square Foot Modular D.E. Filter is a premier, heavy-duty commercial-grade filtration system engineered to deliver unrivaled water clarity for large residential and commercial swimming pools and heavy-use spas. This innovative system seamlessly fuses the unparalleled, microscopic polishing power of Diatomaceous Earth (D.E.) with the low-maintenance, high-flow benefits of modular media technology. Splitting away from traditional multi-grid D.E. configurations that require complex internal breakdown for cleaning, the S7MD60 utilizes a dual-concentric modular cartridge matrix that can be easily hosed down right in place, radically simplifying routine maintenance. The extra-large tank body is injection-molded from a proprietary fiberglass-reinforced composite material, forming a rugged, UV-protected unibody housing designed to comfortably withstand decades of intense chemical exposure, extreme weather, and continuous operating pressures up to 50 PSI. Its balanced, computer-optimized internal hydraulics deliver an exceptionally uniform fluid distribution across its 60 square feet of effective filtration area, trapping algae, dust, and organic contaminants down to 5 microns while supporting a maximum residential design flow rate of up to 120 gallons per minute (GPM). This efficient internal design allows the filter to work in perfect harmony with energy-saving variable speed pumps, reducing overall system backpressure to drastically extend the runtime between necessary cleanings. It features oversized 2-inch female pipe thread (FPT) side bulkhead ports for maximum installation flexibility, enabling direct connection with high-flow multi-port backwash manifolds or slide valves. The dry product weight of the Pentair System:3 PLD Series 60 Sq. Ft. Modular D.E. Filter is approximately 130 pounds (noting that full operational deployment requires an initial pre-coat charging of 9 pounds of standard D.E. filter powder), establishing it as an exceptionally sturdy, reliable, and hydraulically advanced centerpiece for elite pool filtration pads.
