What is the difference between preventive and predictive maintenance? Give an example from a pump manufacturing plant.

Explain that preventive is time-based (e.g., scheduled lubrication) while predictive is condition-based (e.g., vibration analysis). Use a pump example like monitoring bearing temperature to predict failure.

Explain the working principle of a centrifugal pump and common maintenance issues.

Cover impeller rotation, volute casing, and priming. Mention issues like cavitation, seal leakage, and bearing wear, and how to address them.

How do you troubleshoot an electric motor that trips frequently?

List checks: overload, voltage imbalance, insulation resistance, bearing condition, and alignment. Emphasise safety isolation before inspection.

What is the role of a CMMS in maintenance? Have you used any?

Describe how CMMS tracks work orders, spares, and history. If you have internship exposure, mention it; otherwise, show willingness to learn.
