💧 Pentair SuperFlo DOE 1.1 THP Single-Speed High Performance Pool Pump | EC-348190

💧 The Only DOE-Compliant Single-Speed Pool Pump with a NEMA Premium Efficient Motor — Built for Quiet Power and Long-Lasting Performance

📋 Product Overview

The Pentair SuperFlo High Performance Pool Pump (EC-348190) is a DOE-compliant, single-speed inground pool pump engineered to deliver reliable circulation without the noise and energy waste of older models. Rated at 1.1 Total Horsepower (THP) with 0.63 Hydraulic Horsepower (HHP), this pump is designed for smaller residential pools, spas, and pumped water features where a single-speed solution still makes practical sense.

What sets the SuperFlo DOE apart is its NEMA Premium Efficient, Totally Enclosed Fan-Cooled (TEFC) motor — the first and only of its kind in a single-speed pool pump application. This means you get strong water flow, lower energy consumption, and whisper-quiet operation in a compact, durable package. The SuperFlo is also a direct drop-in replacement for the Hayward Super Pump, making upgrades fast and straightforward. If you need a dependable, compliant single-speed pump that won’t quit on you, this is it.

💰 Usage Costs & Running Expenses

Understanding what it costs to run your pool pump is essential for budgeting. Below are estimated annual running costs based on the pump’s nameplate electrical ratings and current US energy prices.

📊 Annual Running Cost Calculation

Assumptions & Data Sources:

• Power Draw: Based on nameplate rating at 230V: 230V × 5.5A = 1,265 watts (1.265 kW maximum draw). Actual power consumption may be slightly lower depending on system conditions and motor power factor.
• Energy Rate: $0.1778 per kWh — US national average residential electricity rate, November 2025 (Source: U.S. Energy Information Administration via Utility Dive, released January 26, 2026)
• Usage Scenarios: Based on industry-standard pool pump run times

⚠ Important: The wattage figure above is calculated from the nameplate voltage and amperage ratings provided by Pentair. Actual real-world power consumption depends on motor power factor, system head pressure, and plumbing conditions. These calculations represent conservative (higher) cost estimates.

🏊 Scenario 1: Typical Summer Pool Season (6 Months)

Running 8 hours per day for 180 days (April through September):

• Daily energy use: 1.265 kW × 8 hours = 10.12 kWh/day
• Season total: 10.12 kWh × 180 days = 1,821.6 kWh
• ✅ Estimated seasonal cost: 1,821.6 kWh × $0.1778 = $323.88

☀ Scenario 2: Year-Round Pool Operation (12 Months)

Running 8 hours per day during summer (180 days) and 4 hours per day during winter (185 days):

• Summer energy: 1.265 kW × 8 hrs × 180 days = 1,821.6 kWh
• Winter energy: 1.265 kW × 4 hrs × 185 days = 936.1 kWh
• Annual total: 1,821.6 + 936.1 = 2,757.7 kWh
• ✅ Estimated annual cost: 2,757.7 kWh × $0.1778 = $490.32

🌊 Scenario 3: Small Pool / Water Feature (Reduced Run Time)

Running 6 hours per day for 180 days:

• Daily energy use: 1.265 kW × 6 hours = 7.59 kWh/day
• Season total: 7.59 kWh × 180 days = 1,366.2 kWh
• ✅ Estimated seasonal cost: 1,366.2 kWh × $0.1778 = $242.91

💡 Energy Rate Note: Your actual costs will vary based on your local electricity rate. The US national average of $0.1778/kWh is just that — an average. Rates range from approximately $0.1193/kWh in North Dakota to $0.402/kWh in Hawaii (EIA data, November 2025). Check your utility bill for your exact rate per kWh.

🎯 Real World Examples & Applications

🏊‍♂ Residential Inground Pool — Standard Filtration

The SuperFlo DOE EC-348190 is purpose-built for residential inground pools that need reliable daily circulation and filtration. With 1.1 THP, it’s sized right for pools up to approximately 15,000–20,000 gallons where a single-speed solution makes sense. Expect steady, quiet operation through the swimming season.

🔄 Upgrading from an Older Pentair SuperFlo or Hayward Super Pump

This is the designated replacement for the discontinued Pentair 340038 and serves as a direct drop-in for Hayward Super Pump installations. The matching footprint and plumbing connections mean minimal modification during the swap — in many cases, you’ll only need to reconnect plumbing unions and wire to the new motor terminal block.

🌊 Pumped Water Features & Fountains

Pentair specifically designed the SuperFlo DOE for smaller pools and pumped water features. The consistent single-speed flow is ideal for fountains, waterfalls, and decorative water features that need steady, uninterrupted water movement.

🛁 Spa & Hot Tub Circulation Support

While primarily a pool pump, the SuperFlo’s compact footprint and quiet TEFC motor make it suitable for spa applications where strong, reliable circulation is required. Its self-priming design ensures consistent performance in spa plumbing configurations.

🏢 Small Commercial / Community Pools

For smaller commercial settings — community HOA pools, apartment complexes, or therapy pools — the SuperFlo DOE provides a budget-friendly, DOE-compliant pump that meets regulatory requirements while keeping operating costs predictable.

💡 Cost Savings Examples

📍 Scenario: Upgrading from a Non-Compliant Pre-DOE Single-Speed Pump

Older single-speed pumps without NEMA Premium Efficient motors typically draw significantly more power. A typical older 1 HP single-speed pump might draw 1,500–1,800 watts compared to the SuperFlo DOE’s maximum 1,265-watt draw.

Conservative Comparison (Using 1,500W for an older pump):

• ❌ Old pump seasonal cost (8 hrs/day, 180 days): 1.500 kW × 1,440 hrs = 2,160 kWh × $0.1778 = $384.05
• ✅ SuperFlo DOE seasonal cost: 1.265 kW × 1,440 hrs = 1,821.6 kWh × $0.1778 = $323.88
• 💵 Estimated annual savings: ~$60 per season
• 📈 5-year estimated savings: ~$300

⚠ Note: The 1,500W figure for older pumps is a conservative industry estimate for pre-DOE single-speed pumps. Actual savings will vary based on the specific pump being replaced. Check your old pump’s nameplate amperage and voltage to calculate your exact savings.

📍 Scenario: Cost Reality Check — Single-Speed vs. Variable-Speed

If you’re considering whether to go single-speed or variable-speed, here’s an honest look:

• ❌ SuperFlo DOE single-speed (8 hrs/day, 180 days): ~$323.88/season
• ✅ A typical variable-speed pump running at low speed (e.g., 1,200 RPM for 12 hrs/day, 180 days): Can cost as little as $50–$100/season
• 💵 Variable-speed advantage: Potentially $200+ per season in energy savings
• ⏱ However: Variable-speed pumps typically cost $300–$600+ more upfront

The Bottom Line: The SuperFlo DOE makes financial sense for smaller pools, water features, or situations where a single-speed pump is the practical choice — such as when your existing plumbing, automation, or budget doesn’t support a variable-speed upgrade. For larger pools with longer run times, a variable-speed pump will pay for itself faster through energy savings.
