🎯 Real World Examples & Applications

🏠 Residential Swimming Pools (30-80m³)

The SR075N is ideally suited for standard domestic swimming pools, delivering 12m³/hour circulation at 8 metres head. For a typical 40m³ residential pool, this provides complete water turnover every 3.3 hours, ensuring crystal-clear water quality and effective chemical distribution. The self-priming capability handles installations where the pump is positioned above water level, while the extra-large basket copes with leaf debris during autumn months.

🌞 Solar-Heated Pool Systems

When paired with solar heating panels, the SR075N’s high-head impeller design overcomes the additional resistance from elevated panel installations and extended pipework runs. The pump maintains efficient flow rates even with solar panels mounted on garage roofs or elevated structures, ensuring your investment in solar heating delivers optimal performance without excessive pump runtime.

🏊‍♂️ Above-Ground and Partially Above-Ground Pools

For above-ground pool installations where the equipment is necessarily positioned below water level, the SR075N’s flooded suction design eliminates priming concerns while the robust construction withstands the higher static pressures. The see-through lid allows quick visual confirmation that the system is operating correctly without interrupting filtration.

🔄 Pool Equipment Upgrades & Replacements

Upgrading from an older, less efficient pump to the SR075N delivers immediate benefits in running costs, noise levels, and reliability. The standard 1.5″ BSP connections ensure compatibility with existing plumbing, while the compact footprint fits typical UK pool plant room layouts. Installers appreciate the quick-access maintenance design that simplifies future service work.

🛁 Large Domestic Hot Tub & Spa Integration

While primarily a pool pump, the SR075N can serve as a dedicated filtration pump for large residential hot tub installations (not suitable for salt chlorinated systems). The continuous-duty motor and thermal protection handle extended runtime requirements, while the sealed bearings ensure quiet operation near living spaces.

• Noise level: Whisper-quiet operation

💵 Annual Operating Saving: £41.47
💷 10-Year Saving: £414.70 (energy alone)
⏱️ Total Cost of Ownership: Significantly lower when factoring in extended lifespan and reduced service costs

📍 Scenario: Energy Price Protection

With UK electricity prices remaining volatile and 75% higher than pre-2021 levels, pump efficiency matters more than ever.

If Electricity Rates Increase to £0.28/kWh (recent peak levels):

❌ Older 0.75kW Pump:

• Annual cost: 0.75 × 1,440 × £0.28 = £302.40

✅ SR075N (0.56kW):

• Annual cost: 0.56 × 1,440 × £0.28 = £225.79
