⚡ Three-Phase Efficiency at Maximum Power

At 3HP, the efficiency advantages of three-phase power become most pronounced. The balanced power delivery significantly reduces electrical losses and mechanical stress compared to single-phase alternatives attempting to deliver similar output.

Pump Configuration	Power Draw	Annual Cost (4,480 hrs)	Notes
✅ Vipool MJB 3HP 3-Phase	2.20 kW	£2,562.56	Optimal efficiency
❌ Typical 3HP Single-Phase	2.60 kW	£3,027.20	+£464.64/year
❌ Older Commercial 3HP	2.80 kW	£3,260.48	+£697.92/year
❌ Industrial Generic Pump	2.90 kW	£3,376.96	+£814.40/year

💡 Engineering Note: Three-phase motors at 3HP typically achieve 5-8% better efficiency than single-phase equivalents, with significantly lower peak current demands. This reduces both energy costs and stress on electrical infrastructure.

💡 Cost Savings Examples

📍 Scenario: Replacing a Worn Commercial Pump

Ageing commercial pumps lose efficiency dramatically – worn bearings, degraded seals, and tired motors can increase power consumption by 25-35%. Replacing a failing pump restores optimal performance and dramatically reduces energy costs.

Factor	Old Worn Pump	New Vipool MJB
Estimated power draw	~2.95 kW (degraded)	2.20 kW
Annual energy (4,480 hrs)	13,216 kWh	9,856 kWh
❌ Old annual cost	£3,436.16	—
✅ New annual cost	—	£2,562.56
💰 Annual savings	—	£873.60

📈 5-Year Projection: £4,368 in energy savings, plus avoided emergency repair costs, reduced downtime, and improved water quality from consistent circulation.

📍 Scenario: Upgrading from Single-Phase to Three-Phase

If your facility has three-phase supply available (common in commercial installations), switching from a single-phase 3HP pump to the three-phase equivalent delivers substantial efficiency gains and extended equipment life.

Factor	3HP Single-Phase	3HP Three-Phase
Power consumption	2.60 kW	2.20 kW
Motor stress	Very high (unbalanced)	Low (balanced)
Expected lifespan	6-8 years	12-15 years
Annual energy (4,480 hrs)	11,648 kWh	9,856 kWh
❌ Single-phase annual cost	£3,028.48	—
✅ Three-phase annual cost	—	£2,562.56
💰 Annual savings	—	£465.92

⏱ Additional benefit: Three-phase motors at this power level typically last 50-80% longer than single-phase equivalents, representing significant capital expenditure savings over facility lifecycle.

📍 Scenario: Right-Sizing from Oversized Industrial Pump

Some installations feature oversized industrial pumps specified for “future expansion” that never materialised. If your facility only requires 36m³/hr, an appropriately-sized quality pump outperforms an oversized generic unit.

Factor	Oversized Industrial Pump	Right-Sized MJB 3HP
Power consumption	2.90 kW	2.20 kW
Flow rate delivered	36 m³/hr	36 m³/hr ✅
Noise level	High	Ultra-quiet
Annual energy (4,480 hrs)	12,992 kWh	9,856 kWh
❌ Industrial pump annual cost	£3,377.92	—
✅ MJB annual cost	—	£2,562.56
💰 Annual savings	—	£815.36

📍 Scenario: Major Commercial Facility – 10-Year Total Cost Analysis

For municipal and commercial operators, total cost of ownership over equipment lifecycle is the critical metric for procurement decisions.

Cost Element	Budget Commercial Pumps	Vipool MJB Three-Phase
Initial purchase	£750	£950
Replacements (10 years)	£1,500 (2 × £750)	£0 (one pump)
Energy (10 years × £3,028)	£30,280	—
Energy (10 years × £2,563)	—	£25,630
