🎯 Real World Examples & Applications

🏊‍♂️ Commercial Swimming Pools

The Malawi 1.5HP three-phase pump is perfectly sized for main circulation duties in pools up to 150m³. Municipal leisure centres benefit from the pump’s continuous-duty rating and robust construction, with the self-priming capability ensuring reliable start-up after maintenance shutdowns. The 21.5 m³/h flow rate provides excellent turnover times whilst the 10-metre nominal head handles typical commercial plantroom configurations.

🏢 Hotel & Resort Pool Facilities

For hospitality settings where quiet operation and reliability are paramount, the balanced three-phase motor delivers noticeably smoother, quieter operation than single-phase alternatives. The IP-55 protection rating ensures dependable performance in enclosed plant rooms where humidity levels can be challenging. Many hotels choose this pump when upgrading from aging Sta-Rite 5P2R installations, benefiting from the drop-in replacement compatibility.

🌊 Water Features & Fountain Systems

Large water features requiring consistent, high-volume flow find the Malawi pump’s performance characteristics ideal. The self-priming capability is particularly valuable in fountain applications where the pump may sit above water level. The corrosion-resistant thermoplastic body withstands the varying water chemistry often encountered in decorative water installations.

🔄 Sta-Rite 5P2R Replacement Upgrades

Facilities operating aging Sta-Rite 5P2R pumps benefit from the Malawi’s identical dimensional specifications. This enables direct replacement without pipework modifications, significantly reducing installation time and costs. The upgrade typically delivers immediate energy savings whilst providing modern reliability and improved serviceability.
