🏊 Vipool MKB+ 9-15 – 0.75HP Pool Pump – Single Phase | 600142

The Perfect Balance of Performance & Efficiency – Smart Bluetooth® Filtration for Medium-Sized Pools

📋 Product Overview

The Vipool MKB+ 9-15 occupies the sweet spot in the MKB+ range, delivering an impressive 9m³/hr flow at 10m head through its efficient 0.75HP motor. This sophisticated French-engineered pump provides the ideal balance between performance and economy—powerful enough for most standard residential pools yet efficient enough to keep running costs firmly under control.

What makes the MKB+ 9-15 particularly compelling is its combination of genuine capability with smart technology integration. The built-in Bluetooth® connectivity via Blueswim EO puts complete pump control at your fingertips, enabling smartphone monitoring, scheduling, and adjustment from anywhere poolside. The innovative Flexible Pocket Filter© technology and generous 940 cm² pre-filter basket deliver exceptional debris management that punches well above this pump’s modest power rating.

Built with premium materials including a stainless steel drain plug and salt-resistant internals, the MKB+ 9-15 handles varied water chemistry, heated installations, and year-round operation with equal confidence. The transparent pre-filter cover allows instant visual inspection, while the proven self-priming mechanism ensures reliable starts every time—even after extended shutdown periods.

Important Note: These pumps feature non-standard union sizes. While they connect to standard pipework, the physical unions differ from most existing models and will require replacement during installation.

🎯 Real World Examples & Applications

🏊‍♂️ Standard Residential Pools (30,000 – 50,000 Litres)

The MKB+ 9-15 delivers ideal circulation for the most common residential pool sizes. At 9m³/hr, a 36,000-litre pool achieves complete turnover every 4 hours—comfortably meeting the recommended two turnovers per 8-hour filtration cycle.

Ideal For:

• Standard rectangular pools (6m × 4m × 1.5m average depth)
• Kidney and freeform pools up to 50m³
• Pools with moderate pipework runs (up to 12m total)
• Most typical UK garden pool installations

🌡️ Heated Pools & Solar Systems

With fluid temperature tolerance up to 50°C and reliable flow capacity, the MKB+ 9-15 handles heated pool applications efficiently:

• Maintains consistent flow through heat exchangers
• Powers solar panel circulation circuits effectively
• Self-primes reliably after heating system maintenance
• Salt-compatible for heated saltwater installations
