The pump is suited to filtration, auto pool cleaning, water feature circulation, backwashing, and pool heating applications operating across larger-volume residential installations.\u003c\/p\u003e\n\n\u003cp\u003eHydraulic 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.\u003c\/p\u003e\n\n\u003cp\u003eWater 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.\u003c\/p\u003e\n\n\u003cp\u003eCorrosion 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.\u003c\/p\u003e\n\n\u003cstrong\u003eFEATURES\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eLarge-capacity 4.5 litre leaf basket supporting reduced cleaning frequency\u003c\/li\u003e\n\u003cli\u003ePatented water-cooled motor configuration for super-quiet operation\u003c\/li\u003e\n\u003cli\u003eIntegrated dry-run protection assisting prevention of pump damage\u003c\/li\u003e\n\u003cli\u003eUV and corrosion-resistant polypropylene body construction\u003c\/li\u003e\n\u003cli\u003e50 mm ABS quick-coupling barrel unions simplifying hydraulic installation\u003c\/li\u003e\n\u003cli\u003eDouble-insulated water circuit with equipotential bonding point provision\u003c\/li\u003e\n\u003cli\u003e316 stainless steel shaft supporting long-term corrosion resistance\u003c\/li\u003e\n\u003cli\u003eArmourspray VC epoxy-coated motor shell developed for outdoor durability\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Davey","offers":[{"title":"Default Title","offer_id":50775429447927,"sku":"SLL400","price":905.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/davey-sll400-polypropylene-water-cooled-single-speed-pool-pump-for-spa-pool-heating-with-large-leaf-basket.png?v=1778738600","url":"https:\/\/foundationpumps.com.au\/products\/davey-sll400-polypropylene-water-cooled-single-speed-pool-pump-for-spa-pool-heating-with-large-leaf-basket","provider":"Foundation Pumps","version":"1.0","type":"link"}
