The document presents a mini project on troubleshooting pumps conducted by Om A. Zavare under the guidance of Prof. Harshada Jadhav at Dr. Babasaheb Ambedkar Technological University. It covers what pumps are, their classifications, common types, troubleshooting techniques, and emphasizes the importance of systematic maintenance to prevent issues. The conclusion highlights the differences between centrifugal and reciprocating pumps regarding maintenance and application suitability.

3. WHAT IS A PUMP?
• Pump is a machine or mechanical equipment which is required to lift a
fluid from low level to high level or to flow fluid from low pressure area
to high pressure area or as a booster in a piping network system.

11. CONCLUSION
• Centrifugal pumps are best suited for large volume applications or for
smaller volumes.
• Reciprocating Pumps require more frequent maintenance than centrifugal
pumps due to the design of the moving parts.
• A step-by-step procedure, adopted in troubleshooting pump and / or
system helps in easily locating the problem and in finding appropriate
solution.
• Consistent and Systematic maintenance of pipes, pumps and other
equipment is essential.
