From Operating Duty to a Replacement Decision

Explore the operating history, field comparison and investment evaluation behind the pump-selection review.

An Engineering Decision in Practice

Follow the Analysis From Operating Duty to Investment

An energy audit at Tüprag Gold Mine identified inefficient pumps. The team used e-MCM to investigate actual operating duty and equipment condition, then evaluate an alternative against the recorded demand.

01 · Establish the Operating Pattern

Follow the Analysis From Operating Duty to Investment

The distribution is concentrated far below the stated BEP of 421.5 m³/h. Frequent operation around 90–115 m³/h is roughly one-quarter of that flow.

That recurring pattern gives an engineer a reason to review pump selection and operating strategy, beyond a single low-flow alarm.

02 · Compare With Field Measurements

Check the Estimate Against an On-Site Flowmeter

The case compares e-MCM flow estimates with instrument readings. The traces follow changes in flow, with a visible offset between estimated and measured values.

The webinar reports deviation of about 3% in this comparison. Accuracy depends on the pump and operating conditions.

03 · Investigate Equipment Condition

Examine Condition Alongside the Hydraulic Duty

The same case includes electrical-signature analysis in its investigation of cavitation and mechanical stress.

Reviewing condition evidence alongside operating duty helps the team investigate both the maintenance concern and the way the pump is being operated.

04 · Evaluate an Alternative

A Replacement Case Built Around the Operating History

The analysis used one year of operating data and evaluated a proposed pump with a 55 kW nominal rating. Estimated annual consumption fell from 602,880 to 264,707 kWh.

The resulting business case forecast approximately $30,436 in annual energy savings against a $39,000 investment.
