Area Network – Pump Testing and Optimization - Reference

Project’s context & challenges

Riventa collaborated with a major South Korean water supplier to assess and optimize it's pumping assets. The project identified significant energy savings and informed refurbishment strategies across eight pumping stations.

The network operates 52 pumps across 8 pumping stations, with varied configurations including fixed-speed and variable-speed units. Historic inefficiencies and oversized pumps required a data-driven diagnostic approach to improve performance and reduce costs.

Solution

Riventa deployed i’s FREEFLOW portable testing technology and applied thermodynamic measurement techniques (ISO 5198) to evaluate pump efficiency, flow rates, and operating conditions. The analysis highlighted oversized pumps, cavitation issues, and scheduling inefficiencies, enabling targeted recommendations for refurbishment and operational changed.
