The Hayward Max-Flo VS SP1811VS<\/strong> is a compact, energy-efficient variable-speed pool pump designed for in-ground pools up to approximately 54,000 litres. Powered by a permanent magnet, totally enclosed fan-cooled (TEFC) motor<\/strong>, the SP1811VS offers four programmable speed settings between 900 and 3,000 RPM, saving up to 75% on energy costs<\/strong> versus a traditional single-speed pump.<\/p>\n Part of Hayward\u2019s trusted Max-Flo VS range, the SP1811VS is engineered for reliability, quiet operation, and long-term value. Its lightweight, corrosion-resistant thermoplastic housing and built-in 1-litre pre-filter basket make installation and maintenance straightforward, while the integrated 24-hour programmable timer gives you full control over your filtration schedule.<\/p>\n The SP1811VS features four selectable speed settings from a quiet 900 RPM up to a powerful 3,000 RPM. Running the pump at lower speeds for extended periods is far more energy-efficient and typically improves filtration quality. The 24-hour digital timer lets you programme each speed independently so your pool is always properly filtered at minimum cost.<\/p>\n Unlike conventional induction motors, the SP1811VS uses a permanent magnet motor<\/strong> with totally enclosed fan cooling (TEFC). This motor type is significantly more efficient across the full speed range, produces less heat, and operates far more quietly. The enclosed design also protects internal components from dust, insects, and humidity.<\/p>\n The pump housing is manufactured from glass-fibre-reinforced thermoplastic<\/strong> \u2014 lightweight, impact-resistant, and immune to corrosion from chlorinated and saltwater pools. The large transparent pre-filter basket (1-litre capacity) is easily accessed via a threaded cover.<\/p>\n The SP1811VS is an excellent choice for pool owners looking to reduce energy bills without compromising filtration performance. At low speeds, the pump runs near-silently \u2014 ideal if your pool equipment is close to a terrace or bedroom. It is suited to in-ground pools with standard 2″ plumbing and is a practical drop-in replacement for older single-speed pumps.<\/p>","protected":false},"excerpt":{"rendered":"Four-speed programmable operation<\/h3>\n
