🎯 Real World Applications
🏊♂️ Large Domestic Swimming Pools
The Lacronite 075 is specifically designed for substantial residential pools up to approximately 60,000 litres. With flow rates of 12 m³/hr at 8m head, it comfortably turns over large pool volumes while operating efficiently. The pump’s quiet operation (74-76 dB) makes it suitable for poolside installations where noise could be a concern.
🔄 STARITE 5P2R Replacement Upgrades
Pool owners with ageing STARITE 5P2R pumps can upgrade seamlessly without any plumbing modifications. This direct replacement capability eliminates installation complexity and costs, making the Lacronite 075 the obvious choice when your existing pump reaches end of life.
♨️ Pools with Heating Systems
The pump’s consistent flow characteristics ensure optimal heat exchanger performance. Whether using gas, oil, or heat pump heating, the Lacronite 075 delivers the reliable circulation needed for efficient heat transfer and even temperature distribution throughout your pool.
🌊 In-Floor Cleaning Systems
Modern in-floor cleaning systems demand steady, reliable flow to operate effectively. The Lacronite 075’s hydraulically efficient design provides the consistent pressure and flow these systems require for comprehensive pool floor cleaning.
💦 Swim Jets & Counter-Current Units
For fitness swimming applications, the Lacronite 075 handles the additional resistance of swim jet systems effectively. Its robust motor and thermal protection ensure reliable operation even under the sustained loads these systems demand.
🧂 Salt Water Chlorination Systems
The premium 316 stainless steel mechanical seal provides exceptional resistance to the corrosive effects of salt water chlorination, ensuring long service life in salt pools where lesser seals would fail prematurely.
