🎯 Real World Applications

🏊‍♂️ Large Residential Swimming Pools

The Lacronite 150 is purpose-built for substantial domestic pools from 70,000 to 100,000+ litres. With flow rates reaching 19 m³/hr at 8m head, it delivers the rapid turnover large pools demand for maintaining pristine water quality. Where smaller pumps struggle to circulate dead spots, the Lacronite 150 ensures comprehensive water movement throughout your pool.

🏨 Holiday Lets & Guest Accommodation

Rental properties with pools face unique demands – heavy usage, variable bather loads, and the absolute requirement for crystal-clear water to satisfy guests. The Lacronite 150’s robust construction and powerful output handles intensive use patterns while its premium components ensure reliability throughout the busy season.

♨️ High-Capacity Heating Systems

Large pools with heating require pumps capable of maintaining optimal flow through heat exchangers even when system resistance increases. The Lacronite 150’s powerful motor handles high head pressure scenarios that would overwhelm lesser pumps, ensuring efficient heat transfer and even temperature distribution.

🌊 Multiple Water Features

Pools featuring spillovers, fountains, deck jets, and raised features demand significant hydraulic capability. The Lacronite 150 provides ample power to run multiple water attractions while maintaining adequate filtration flow – something smaller pumps simply cannot achieve.

🔄 Complex Ancillary Systems

Modern pool installations often combine in-floor cleaning, automatic vacuum ports, heating, and sanitisation equipment. The Lacronite 150’s generous flow capacity handles the combined resistance of multiple systems without compromising circulation effectiveness.

💦 Professional Swim Jets

Serious counter-current swim systems require substantial, sustained flow. The Lacronite 150 delivers the power competitive swimmers and fitness enthusiasts need for effective training, with thermal protection ensuring safe extended operation.

🏗️ Light Commercial Installations

Small hotel pools, spa facilities, and leisure centre splash pools benefit from the Lacronite 150’s commercial-grade capability without the complexity and cost of three-phase power installation.
