💧 CP400S Hurricane Pump | 4.0HP (2.9kW) Three-Phase Commercial Pool Pump with Pre-Filter

Professional-grade water circulation for medium to large pools, spas, and aquatic facilities 🏊‍♂️

📋 Product Overview

The CP400S Hurricane is Certikin’s entry-level commercial-grade centrifugal pump, engineered to deliver the robust performance of traditional cast iron pumps with the superior chemical resistance and lightweight advantages of modern composite construction. Rated at 4.0HP (2.9kW), this three-phase pump is specifically designed for medium to large swimming pools, commercial spas, and aquatic facilities requiring reliable, continuous water circulation at high flow rates.

Unlike residential single-phase pumps, the CP400S operates on three-phase power (230/400V), providing superior efficiency, reduced energy consumption, and extended operational life. The integrated stainless steel pre-filter protects the pump from debris while the flooded suction design ensures optimal performance and longevity. Whether you’re managing a community pool, boutique hotel spa, or large residential installation, the CP400S delivers consistent, powerful circulation with minimal maintenance requirements.

Key differentiator: The CP400S combines commercial-grade reliability with chemical-resistant construction at an accessible price point, making it ideal for operators upgrading from residential pumps or replacing aging cast iron units.

🎯 Real World Examples & Applications

🏊‍♂️ Community Swimming Pools (15m × 10m, 300,000L)

The CP400S is ideally sized for medium community pools requiring continuous filtration during operating hours. With flow rates up to 102 m³/hr, it achieves complete pool turnover every 3 hours, meeting public health regulations for recreational facilities. The stainless steel pre-filter handles high debris loads from multiple swimmers while the chemical-resistant body withstands heavy chlorination protocols.

Typical installation: Planted poolside in below-ground pump room, connected to sand or cartridge filtration system via 90mm pipework, operating 8-12 hours daily.

---

🛁 Commercial Spa Facilities & Health Clubs

Perfect for spa complexes with multiple hot tubs, hydrotherapy pools, or large jet-driven systems. The CP400S handles elevated water temperatures up to 40°C while maintaining consistent pressure for therapeutic jets. Three-phase operation ensures quiet running—essential in relaxation environments where noise pollution must be minimized.

Typical installation: Indoor plant room installation feeding 2-3 hydrotherapy pools, operating on timer controls with variable run times based on occupancy.

---

🏢 Hotel & Resort Pool Systems

Boutique hotels and resort properties benefit from the CP400S’s commercial-grade reliability without the excessive capacity of larger industrial pumps. The lightweight composite construction simplifies rooftop installations where structural loading is a concern, while the IP55 rating withstands coastal environments and weather exposure.

Typical installation: Rooftop or terrace pump room feeding infinity pools or feature pools, operating 6-8 hours daily with automated controls.

🔄 Upgrade from Residential Pumps

Property owners with large residential pools (80,000L+) often find residential pumps inadequate—running continuously, overheating, or failing prematurely. The CP400S upgrade provides proper capacity with superior reliability. The flooded suction design eliminates the priming issues common with residential pumps, while three-phase efficiency dramatically reduces running costs.

Typical installation: Replacing 2HP or 3HP residential pumps in large private pools (20m+), retrofit via existing 90mm pipework with electrical upgrade to three-phase supply.

🌊 Water Features & Koi Ponds

High-capacity ornamental ponds, waterfalls, and architectural water features benefit from the CP400S’s high flow rates and chemical resistance. The plastic composite body prevents staining from tannins and organic compounds while the stainless steel components resist corrosion in natural water environments.

Typical installation: Dry-pit installation feeding multiple waterfall outlets, ornamental fountains, or large koi pond filtration systems requiring 80-100 m³/hr circulation.

💡 Cost Savings Examples

💰 Scenario: Replacing a 15-Year-Old Cast Iron Pump

Many facilities still operate aging cast iron centrifugal pumps installed in the 2000s. These pumps typically draw 3.8-4.5kW at equivalent horsepower due to inefficient motor technology and corrosion-related performance degradation.

📍 Old Cast Iron 4HP Pump:

• Power consumption: 4.2 kW (degraded efficiency)
• Annual usage: 2,500 hours (community pool)
• ❌ Annual cost: 4.2 × 2,500 × £0.2635 = £2,767.25

📍 New CP400S Hurricane:

• Power consumption: 2.9 kW
• Annual usage: 2,500 hours
• ✅ Annual cost: 2.9 × 2,500 × £0.2635 = £1,910.13

💵 Annual Saving: £857.12
📈 5-year savings: £4,285.60
⏱ Payback period: Approximately 2.5-3 years (considering installation costs and pump price)

💰 Scenario: Commercial Pool Operating Cost Reduction

A swimming academy with 12-hour daily operation compares their existing oversized 7.5HP pump (5.5kW) against properly sizing with a CP400S:

❌ Oversized 7.5HP Pump:

• Power: 5.5 kW
• Usage: 12 hours/day × 300 days = 3,600 hours
• Annual cost: 5.5 × 3,600 × £0.2635 = £5,215.86

✅ Correctly Sized CP400S:

• Power: 2.9 kW
• Usage: Same operational hours
• Annual cost: 2.9 × 3,600 × £0.2635 = £2,750.22

💷 Annual Saving: £2,465.64
📊 Over 10-year pump life: £24,656.40 in energy savings
⚡ Energy reduction: 47% lower consumption

💰 Scenario: Single-Phase to Three-Phase Conversion

A large residential pool currently operates a 4HP single-phase pump (3.5kW, 16.2A) that runs hot and requires frequent circuit breaker resets during peak summer:

❌ Single-Phase 4HP Pump Issues:

• Power: 3.5 kW
• Usage: 8 hours/day × 180 days = 1,440 hours
• Annual cost: 3.5 × 1,440 × £0.2635 = £1,328.64
• Additional costs: Frequent motor replacements (£400-600 every 3-4 years)

✅ CP400S Three-Phase Upgrade:

• Power: 2.9 kW
• Usage: Same hours
• Annual cost: 2.9 × 1,440 × £0.2635 = £1,101.74
• Extended motor life: 8-10 years typical lifespan

💸 Annual energy saving: £226.90
💰 Equipment longevity saving: £150-200 per year (amortized replacement costs)
📈 Total annual benefit: Approximately £380-430

Note: Three-phase supply installation costs £800-1,500 depending on existing electrical infrastructure proximity.
