🎯 Real World Examples & Applications

🏊 Medium to Large Residential Pools

Perfect for domestic pools ranging from 50,000 to 80,000 litres (11,000 to 17,600 gallons). The 1HP motor provides strong circulation for effective filtration while the hydraulically efficient design keeps running costs reasonable. Ideal for pools measuring 8m × 4m up to 10m × 5m with depths between 1.2m and 1.8m. The 50mm connections handle the flow requirements efficiently, and the large strainer basket means less frequent cleaning even with nearby trees or heavy bather loads.

🛁 Pools with Ancillary Systems

Excellent choice when your pool setup includes additional equipment such as solar heating panels, heat exchangers, in-floor cleaning systems, or water features. The WRSS101 delivers sufficient head pressure to overcome the resistance of these systems while maintaining adequate filtration flow. The reliable motor and secondary seal protection provide peace of mind for installations where the pump runs extended hours to serve multiple functions.

🏢 Light Commercial Applications

Well-suited for small commercial installations including B&B properties, small holiday lets with shared pools, countryside hotels, or leisure lodges. The robust construction and thermal protection handle the extended run times required for commercial use, while the single-phase motor keeps electrical installation costs reasonable. The secondary seal technology significantly reduces maintenance call-outs and downtime – critical factors for commercial operations.

🔄 Upgrade Projects

Ideal replacement for aging or failing pumps where you need proven reliability without oversizing. Common upgrade scenarios include replacing noisy older pumps, undersized pumps that can’t maintain proper filtration turnover, or pumps with recurring seal failures that threaten motor damage. The quick-connect unions often match existing plumbing, simplifying retrofits, while the improved efficiency immediately reduces operational costs.

☀ Seasonal Pool Installations

Perfect for UK residential pools operated seasonally from late spring through early autumn. The drain plugs facilitate complete winterization to protect against frost damage, while the durable construction withstands the annual seasonal cycles. The efficient operation keeps electricity costs manageable during the active season, and the thermal protection guards against issues during hot summer operating conditions.
