💪 Pentair Sta-Rite HD 2.0 HP Single Phase Pool Pump

Maximum Single-Phase Power from Italian Engineering – 29 m³/hr Flow for Large Pools and Demanding Installations 🔥

📋 Product Overview

The Pentair Sta-Rite HD 2.0 HP represents the pinnacle of the single-phase Sta-Rite HD range—delivering maximum circulation power for large residential pools, heated installations, and semi-commercial applications where standard pumps simply cannot keep pace. With an impressive 29 m³/hr flow rate at 8m head from a robust 1.5 kW motor, this pump handles pools up to 180m³ with authority.

Manufactured 100% at Pentair’s state-of-the-art facility in Pisa, Italy, the 2.0 HP model shares the same exceptional build quality as the entire HD range whilst delivering substantially more power. The induction asynchronous motor features a bi-material shaft with AISI 304 stainless steel drive-end, paired with premium SKF sealed bearings—the same bearing brand trusted in automotive and aerospace applications.

For pool owners with larger volumes, extended pipework runs, water features, or heated pools requiring rapid turnover, the 2.0 HP provides the circulation capacity needed without stepping up to three-phase power supply. The signature XL pre-filter basket handles heavy debris loads whilst the PPO resin sleeved impeller delivers saltwater compatibility up to 0.40%.

Backed by Pentair’s comprehensive 3-year warranty including bearings, the Sta-Rite HD 2.0 HP is the definitive choice when maximum single-phase performance meets Italian engineering excellence.

Choose the 2.0 HP when:

• Your pool exceeds 120,000 litres (120 m³)
• Extended pipework creates significant friction losses
• Multiple water features share the circulation system
• Heated pools require rapid turnover for efficient heat distribution
• You prefer shorter daily runtime with maximum flow
• Semi-commercial reliability is required

🎯 Real World Applications

🏊‍♂️ Large Luxury Residential Pools (100,000–180,000 Litres)

The Sta-Rite HD 2.0 HP is purpose-built for substantial private pools where smaller pumps would require impractically long daily runtimes. With 29 m³/hr flow, a 120,000-litre pool achieves complete turnover in just over 4 hours—maintaining exceptional water quality with comfortable filtration schedules.

🌊 Pool + Water Feature Combinations

Where a single pump serves both main circulation and water features—fountains, waterfalls, spillovers, or deck jets—the 2.0 HP provides ample capacity to power decorative features without compromising filtration performance.

♨️ Large Heated & Indoor Pools

Heated pools demand faster circulation to distribute warmth evenly, work efficiently with heat exchangers, and prevent temperature stratification. The 29 m³/hr flow rate ensures consistent temperatures throughout larger pool volumes whilst maintaining excellent filtration.

🏠 Properties Without Three-Phase Supply

Many substantial residential properties lack three-phase electrical supply, limiting pump options. The Sta-Rite HD 2.0 HP delivers near-commercial performance on standard single-phase power—eliminating the need for expensive electrical infrastructure upgrades.

🔄 5P6R Series Replacement & Upgrades

The Sta-Rite HD is a direct replacement for the popular 5P6R series with identical connection sizes and mounting dimensions. Pool owners upgrading from 1.5 HP to 2.0 HP gain 12% more flow with no pipework modifications—simply swap and enjoy enhanced circulation.

🏨 Boutique Hotel & Holiday Let Pools

Semi-commercial installations requiring reliable, high-flow circulation without the complexity of three-phase power. The 3-year warranty and premium construction provide confidence for business operators.

💡 Cost Savings Examples

📍 Scenario: Upgrading from an Ageing 2.0 HP Pump

Older pumps typically consume 25–35% more electricity than modern equivalents due to worn impellers, degraded bearings, and outdated motor technology.

Example comparison:

• ❌ Aged pump power draw: approximately 2.00 kW
• ✅ New Sta-Rite HD 2.0 HP: 1.5 kW
• Usage: 8 hours/day × 150 days = 1,200 hours annually

Annual energy consumption:

• ❌ Old pump: 2.00 kW × 1,200 = 2,400 kWh = £632.40
• ✅ Sta-Rite HD: 1.5 kW × 1,200 = 1,800 kWh = £474.30

💰 Annual saving: £158.10

📈 5-year savings: £790.50

⏱️ Payback on efficiency gains: approximately 4.6 years

📍 Scenario: Choosing Quality Over Budget Equipment

Budget pumps sacrifice hydraulic efficiency for lower purchase prices. Total cost of ownership reveals the true value.

5-year comparison (8 hours/day, 150 days/year = 1,200 hours annually):

Factor	Budget 2.0 HP	Sta-Rite HD 2.0 HP
Purchase price	£500	£723.99
Power consumption	1.80 kW	1.5 kW
Annual energy cost	£569.16	£474.30
5-year energy cost	£2,845.80	£2,371.50
Expected lifespan	3–5 years	8–12 years
Warranty	1 year	3 years
5-year total cost	£3,345.80	£3,095.49

💷 The Sta-Rite HD costs £250.31 LESS over 5 years—with potentially double the lifespan remaining

📍 Scenario: Right-Sizing from an Oversized 3.0 HP Pump

Many pools have oversized pumps creating unnecessary energy costs. Downsizing to correct capacity maintains water quality whilst substantially cutting bills.

Example comparison:

• ❌ Oversized 3.0 HP pump: 2.20 kW
• ✅ Right-sized Sta-Rite HD 2.0 HP: 1.5 kW
• Year-round heated pool: 10 hours/day × 365 days = 3,650 hours

Annual energy consumption:

• ❌ 3.0 HP pump: 2.20 kW × 3,650 = 8,030 kWh = £2,115.91
• ✅ Sta-Rite HD: 1.5 kW × 3,650 = 5,475 kWh = £1,442.66

💰 Annual saving: £673.25

📈 3-year savings: £2,019.75

⏱️ Payback period: approximately 13 months

---

📍 Scenario: Avoiding Three-Phase Installation Costs

For properties without three-phase power, installing a three-phase supply can cost £2,000–£5,000+. The Sta-Rite HD 2.0 HP delivers substantial performance on standard single-phase power.

Potential savings:

• ❌ Three-phase installation: £2,500–£5,000 (typical)
• ❌ Three-phase pump cost: £700–£900
• ✅ Sta-Rite HD 2.0 HP: £723.99

💷 Potential saving: £2,500–£5,200 by avoiding three-phase upgrade
