💧 Pentair Sta-Rite 5P2R 0.75HP Single Phase Pool Pump (5P2RD-1)

Italian-Engineered Excellence for Reliable Pool Circulation – Built to Outlast and Outperform

📋 Product Overview

The Pentair Sta-Rite 5P2R 0.75HP is a precision-engineered swimming pool pump manufactured at Pentair’s renowned facility in Pisa, Italy. This single-phase centrifugal pump delivers exceptional performance with a flow rate of up to 12m³/hr, making it ideal for residential pools and smaller commercial applications.

Built around a heavy-duty induction motor featuring a one-piece stainless steel shaft and permanently lubricated SKF sealed bearings, the 5P2R series is designed for continuous, whisper-quiet operation.

💰 Usage Costs & Running Expenses

Understanding your running costs is essential for budgeting and comparing pump options. Here’s a detailed breakdown of what you can expect to pay operating this Sta-Rite 5P2R pump.

📊 Annual Running Cost Calculation

Power consumption: 0.88 kW (power input P1) UK electricity rate: £0.26 per kWh (UK average, Q4 2025)

🏊 Scenario 1: Typical Residential Pool (Summer Season)

• Usage: 8 hours/day × 180 days (6-month season) = 1,440 hours/year
• ✅ Annual cost: 0.88 kW × 1,440 hours × £0.26 = £329.47
• Monthly cost during season: £54.91

🏊 Scenario 2: Year-Round Heated Pool

• Usage: 6 hours/day × 365 days = 2,190 hours/year
• ✅ Annual cost: 0.88 kW × 2,190 hours × £0.26 = £500.91
• Monthly cost: £41.74

☀ Scenario 3: Light Residential Use

• Usage: 6 hours/day × 150 days (5-month season) = 900 hours/year
• ✅ Annual cost: 0.88 kW × 900 hours × £0.26 = £205.92
• Monthly cost during season: £41.18

⚡ Energy Efficiency Advantage

The Sta-Rite 5P2R series motors are engineered for maximum efficiency, featuring:

• Class F insulation – Handles higher operating temperatures without efficiency loss
• 2,850 RPM optimised speed – Balanced performance without excessive energy draw
• Permanently lubricated bearings – Reduce friction losses over the pump’s lifetime
• Precision-molded impeller – Smooth water passages minimise turbulence and energy waste

🎯 Real World Examples & Applications

🏊‍♂️ Residential Swimming Pools

The 0.75HP output delivers ideal circulation for pools up to 50,000 litres (approximately 11,000 gallons). Perfect for typical UK garden pools requiring 2-3 complete water turnovers daily. The self-priming design handles standard suction lifts with ease, while quiet operation means you can run the pump without disturbing neighbours or outdoor relaxation.

🌊 Saltwater Pool Systems

With salt resistance up to 0.4%, this pump is specifically designed to handle the corrosive nature of saltwater chlorination systems. The stainless steel shaft and corrosion-resistant thermoplastic body ensure longevity in salt-treated pools where lesser pumps would deteriorate rapidly.

🛁 Spa & Hot Tub Circulation

The compact footprint and reliable thermal protection make this pump suitable for spa circulation applications. The 52°C maximum liquid temperature rating accommodates heated spa water, whilst the IP-55 protection handles humid plant room environments.

🔄 Replacement & Upgrade Applications

Direct replacement for older Sta-Rite 5P2R models and compatible with many competitor installations using 1½” BSP connections. The Hi-Rise mounting base simplifies retrofitting, and the proven reliability means fewer callbacks and warranty claims compared to budget alternatives.

🏢 Small Commercial Installations

Holiday let pools, small hotel plunge pools, and private health club pools benefit from the industrial-grade construction and extended warranty coverage. The 3-year warranty including bearings provides peace of mind for commercial operators where downtime means lost revenue.

💡 Cost Savings Examples

📍 Scenario: Upgrading from an Old Single-Speed Pump

Many older pool pumps operate at 1.1kW or higher for similar flow rates. Upgrading to the efficient Sta-Rite 5P2R can deliver significant savings:

Old pump consumption: 1.1 kW Sta-Rite 5P2R consumption: 0.88 kW Annual usage: 1,440 hours (typical season) Electricity rate: £0.26/kWh

Pump	Calculation	Annual Cost
❌ Old 1.1kW pump	1.1 × 1,440 × £0.26	£411.84
✅ Sta-Rite 5P2R	0.88 × 1,440 × £0.26	£329.47
💰 Annual Saving		£82.37

📈 5-Year Saving: £411.85

📍 Scenario: Choosing Quality vs Budget Alternatives

Budget pumps often have shorter lifespans (2-3 years) and higher failure rates. The Sta-Rite’s 3-year warranty and proven reliability offer true value:

Budget pump: £180 + replacement every 3 years = £360 over 6 years Sta-Rite 5P2R: Higher initial investment, but typically 8-10+ years service life

✅ Reduced replacement costs ✅ Lower energy consumption ✅ Fewer service callouts ✅ Less pool downtime

📍 Scenario: Commercial Pool Operator (Year-Round Use)

Annual usage: 3,650 hours (10 hours/day, 365 days) Electricity rate: £0.26/kWh

Comparison	Calculation	Annual Cost
❌ Competitor 1.0kW pump	1.0 × 3,650 × £0.26	£949.00
✅ Sta-Rite 5P2R (0.88kW)	0.88 × 3,650 × £0.26	£835.12
💷 Annual Saving		£113.88

⏱ Payback on efficiency upgrade: Under 3 years for typical commercial installations
