Large residential pools and high-demand swim spa systems can integrate the Davey SLL400 Silensor where powerful recirculation performance and quieter equipment operation are required for continuous filtration duty. The pump is suited to filtration, auto pool cleaning, water feature circulation, backwashing, and pool heating applications operating across larger-volume residential installations.
Hydraulic performance reaches approximately 460 L/Min with maximum head capability extending to approximately 22 m depending on operating conditions. The pump operates through a single-phase 240V motor utilizing 1.76 kW input power to maintain strong single-speed water movement and efficient turnover performance across larger filtration systems.
Water circulation efficiency is supported through a centrifugal hydraulic configuration combined with Davey’s patented water-cooled motor design, helping minimize operating vibration and maintain quieter performance throughout extended operating cycles. Integrated dry-run protection assists reduction of internal wear if water supply becomes interrupted, while the large 4.5 litre leaf basket supports longer maintenance intervals through increased debris collection capacity.
Corrosion and UV-resistant polypropylene construction contributes durability within exposed outdoor pool equipment environments and chemically treated water systems. Installation is simplified through 50 mm inlet and outlet connections supplied with quality ABS quick-coupling barrel unions. Additional engineering details include double insulation to the water circuit with equipotential bonding provision, a 316 stainless steel shaft, Armourspray VC epoxy motor shell coating, and drain plug access for simplified servicing procedures.
