🎯 Real World Examples & Applications

🏊‍♂️ Large Domestic Swimming Pools

The Lacronite 050 excels in pools up to 60,000 litres, providing complete turnover every 6 hours at standard head pressures. Its quiet operation (approximately 70-72 dB at typical flow rates) makes it suitable for pools near entertainment areas or neighbouring properties.

🔄 STARITE 5P2R Replacement Projects

Pool owners with ageing STARITE 5P2R pumps benefit from a straightforward upgrade path. The identical footprint and connection configuration means your existing pipework, electrical supply, and mounting remain unchanged—simply disconnect the old pump and connect the Lacronite 050.

☀️ Solar Heating Circuit Pumps

The efficient hydraulic design makes the Lacronite 050 ideal as a dedicated solar panel circulation pump. At 10 m³/hr flow rate, it provides optimal heat transfer through roof-mounted solar collector arrays whilst maintaining low energy consumption.

🌊 Water Feature & Fountain Supply

Pools with integrated water features, deck jets, or spillover designs benefit from the Lacronite’s consistent pressure delivery. The 0.5hp output handles moderate head requirements whilst keeping operating costs manageable.

🛁 Swim Jet & Spa Integration

For pools equipped with swim jet systems or integrated spa sections, the Lacronite 050 serves as a reliable secondary circulation pump, handling dedicated feature circuits without oversizing your main filtration system.

🏠 In-Floor Cleaning Systems

The pump’s optimised flow characteristics make it well-suited for powering in-floor cleaning systems, providing consistent water distribution to pop-up heads whilst the main pump handles filtration duties.
