Pump station efficiency testing in Brazil - Case Study

Reducing pumping costs for a major municipal water company at a downtown clean water pumping station in Sao Paulo

We directly measured the efficiency of three 700CV water distribution pumps using our FREEFLOW portable pump testing system. We yielded immediate knowledge that major energy savings existed – results that were viewed with keen interest by the client. With Brazil an emerging market for us, we were pleased to demonstrate that FREEFLOW could accurately determine real-time pump efficiency.

Our fuller 2-page case study offers in-depth analysis of the above project. It details the assets we tested, the challenges we overcame, our approach and the results we achieved.

Our results in brief:

• Savings of between R$160k to R$580k per year available through refurbishment and/or replacement
• Pump rescheduling would increase operating efficiency by at least 15% (approx R$75k), with no capital outlay
• By refurbishing 2 pumps station efficiency could be up 42%
• Installing new pumps could improve pump efficiency from the current best of 75% to an acheivable 86%
