🎯 Real World Examples & Applications

🏊‍♂️ Large Residential Swimming Pools The AV250-2DN-S excels in pools ranging from 60,000 to 120,000 litres (13,000-26,000 gallons). For a typical 10m × 5m × 1.5m pool (75,000L), the 240 LPM flow rate provides complete water turnover in approximately 5 hours, meeting recommended filtration standards. The self-priming feature allows installation in a poolside equipment shed up to 3 meters above water level, eliminating the need for underground pump chambers.

🛁 Commercial Spa & Hydrotherapy Systems Multiple spa installations benefit from the AV250’s consistent pressure delivery and chemical-resistant construction. Hotels, gyms, and therapy centres rely on this pump for high-usage environments where reliability is critical. The IPX5 motor protection handles the humid conditions typical of indoor spa facilities, while the 20-meter head capability manages complex plumbing layouts with multiple jets and features.

🌊 Water Features & Koi Ponds For ornamental water features requiring strong circulation, the AV250 provides the necessary flow to maintain water quality in large ponds (up to 100,000 litres). The transparent strainer basket is particularly valuable for debris-heavy environments, allowing quick visual inspection without system shutdown. The quiet operation (66-68 dB) ensures the pump doesn’t detract from the tranquil ambience of garden installations.

🔄 Pool Upgrade Projects Replacing aging 2-3HP pumps with the modern AV250 delivers immediate benefits: reduced energy consumption (20%+ savings), quieter operation, improved reliability, and enhanced safety through TÜV certification. The standard 2¾” BSP connections ensure compatibility with existing plumbing, making retrofits straightforward. Many customers report noticing clearer water due to improved circulation efficiency.

🏢 Light Commercial & Semi-Public Pools Holiday parks, B&Bs, and small apartment complexes with shared pools find the AV250 ideal for applications requiring robust performance without three-phase electrical requirements. The single-phase 230V operation means installation in locations where three-phase power isn’t available or would be cost-prohibitive to install. TÜV certification satisfies public pool safety regulations in many jurisdictions.
