💧 Norsup Variable Speed Pool Pump 2″ x 1.5″ – 230VAC – Evo Pro Modbus – 1.5HP

Quiet, Energy-Efficient, and Fully Programmable Circulation for Modern Pools

📋 Product Overview

The Norsup Variable Speed Pool Pump 1.5HP Evo Pro Modbus delivers the perfect balance of performance, efficiency, and intelligent control for residential swimming pools. This German-engineered pump combines advanced variable speed technology with a user-friendly integrated control panel, allowing you to programme up to five different speeds throughout the day for optimal filtration and maximum energy savings.

Unlike conventional single-speed pumps that consume energy at full power regardless of actual requirements, the Evo Pro Modbus features a permanent magnet motor that adjusts speed precisely to match your pool’s needs. The intelligent skimmer function automatically boosts speed at programmed intervals to clear floating debris from the water surface, maintaining pristine pool conditions without manual intervention.

Built for long-term reliability, this pump features a premium German motor, 316 stainless steel shaft, and saltwater-resistant construction rated up to 0.4% concentration. Whether you’re upgrading from an aging pump or specifying equipment for a new installation, the Evo Pro Modbus offers whisper-quiet operation, dramatic energy savings, and the flexibility to integrate with external pool automation systems via the included Modbus control cable.

💰 Usage Costs & Running Expenses

One of the most significant advantages of variable speed pump technology is the dramatic reduction in electricity costs. Thanks to the Pump Affinity Law, reducing pump speed by just 50% can cut energy consumption by up to 87.5%.

📊 Annual Running Cost Calculation

Assumptions:

• UK electricity rate: £0.26 per kWh (Q4 2025 average)
• Typical seasonal pool use: 180 days (April – September)
• Daily operation: 8-12 hours depending on speed setting

Variable Speed Operation (Recommended):

Running at optimised variable speeds throughout the day:

• 2 hours at high speed (1.1 kW): 1.1 kW × 2 hrs = 2.2 kWh
• 10 hours at low speed (0.25 kW): 0.25 kW × 10 hrs = 2.5 kWh
• Daily consumption: 4.7 kWh
• ✅ Annual cost: 4.7 kWh × 180 days × £0.26 = £220.00

Single-Speed Pump Comparison (1.1 kW running 8 hours):

• 1.1 kW × 8 hours = 8.8 kWh per day
• ❌ Annual cost: 8.8 kWh × 180 days × £0.26 = £411.84

💵 Annual Savings Summary

Operating Method	Daily kWh	Annual kWh	Annual Cost
❌ Single-Speed Pump (8 hrs/day)	8.8 kWh	1,584 kWh	£411.84
✅ Variable Speed Optimised	4.7 kWh	846 kWh	£220.00
💰 Your Savings	4.1 kWh	738 kWh	£191.84/year

⚡ Energy Saving: 47% reduction in electricity consumption

For pools requiring 24-hour circulation, the savings become even more dramatic. Running a variable speed pump continuously at low speed (0.25 kW) costs approximately £281/year compared to £1,029/year for a single-speed pump running 12 hours – a saving of over £748 annually.

🎯 Real World Examples & Applications

🏊‍♂ Standard Residential Pools (30-60 m³)

The 1.5HP Evo Pro Modbus is perfectly sized for typical residential pools. With flow capacity up to 24 m³/h, it comfortably handles pools between 30-60 cubic metres, turning over the water volume multiple times daily for crystal-clear results.

Typical setup: 4 hours medium speed + 8 hours low speed = complete turnover with minimal energy use

🏠 Family Home Pools

For everyday family pools, the programmable timer ensures the pump runs at higher speeds during peak swimming hours and reduces to efficient low-speed filtration overnight. The quiet operation means no disturbance during evening relaxation by the pool.

Key benefit: Programme higher speeds for afternoon swimming, lower speeds overnight

🔄 Upgrading from Older Single-Speed Pumps

The universal retrofit design makes upgrading straightforward. Direct bolt-on replacement for Badu Bettar, Top II, Badu 90, Badu Magna, Badu Prime, and similar models means minimal installation time and immediate energy savings.

ROI advantage: Energy savings typically pay back the upgrade cost within 2-3 seasons

♨ Pools with Heat Pumps

Variable speed operation is particularly beneficial for heated pools. The consistent, low-speed circulation distributes warmth evenly while reducing the thermal demand – your heat pump works less when water flows continuously at lower rates.

Efficiency boost: Improved heat distribution reduces overall heating costs by 10-15%

🛁 Swim Spas & Compact Installations

The 1.5HP rating provides ample power for swim spas and smaller installations where the 2HP model would be oversized. The compact design and universal connections make installation straightforward in tight plant rooms.

Perfect fit: Right-sized performance without overpowering compact systems

💡 Cost Savings Examples

📍 Scenario 1: Replacing an Aging Single-Speed Pump

Situation: Your 8-year-old 1HP single-speed pump runs 8 hours daily during the swimming season.

Current costs:

• ❌ Old pump consumption: 0.9 kW × 8 hrs × 180 days = 1,296 kWh
• ❌ Annual electricity: 1,296 × £0.26 = £336.96

With Norsup Evo Pro Modbus 1.5HP:

• ✅ Variable speed operation: 4.7 kWh × 180 days = 846 kWh
• ✅ Annual electricity: 846 × £0.26 = £220.00
• 💰 Annual saving: £116.96
• 📈 5-year saving: £584.80
• ⏱ Typical payback period: 4-5 swimming seasons

📍 Scenario 2: Running 24/7 for Optimal Water Quality

Situation: You want continuous circulation for the best possible water clarity and chemical distribution.

Single-speed pump running 10 hours:

• ❌ 1.1 kW × 10 hrs × 180 days = 1,980 kWh
• ❌ Annual cost: £514.80

Variable speed pump running 24 hours at low speed + 2 hours boost:

• ✅ (0.2 kW × 22 hrs) + (1.1 kW × 2 hrs) = 4.4 + 2.2 = 6.6 kWh/day
• ✅ Annual: 6.6 × 180 = 1,188 kWh
• ✅ Annual cost: £308.88
• 💰 Annual saving: £205.92
• 📈 5-year saving: £1,029.60

📍 Scenario 3: New Build Pool Installation

Situation: Specifying equipment for a new 45m³ residential pool build.

Option A – Standard single-speed pump:

• ❌ Purchase cost: ~£350
• ❌ Annual running: 1.1 kW × 8 hrs × 180 days × £0.26 = £411.84
• ❌ 5-year total cost: £350 + £2,059 = £2,409

Option B – Norsup Evo Pro Modbus 1.5HP:

• ✅ Purchase cost: ~£800
• ✅ Annual running: 4.7 kWh × 180 days × £0.26 = £220.00
• ✅ 5-year total cost: £800 + £1,100 = £1,900
• 💰 5-year saving vs single-speed: £509
• 📈 10-year saving: £1,468
