Piping Design Considerations for Reciprocating VS Centrifugal Pumps

Contents :-
1.Introduction: Centrifugal vs. Reciprocating Working Principles

2.Piping Design

• Centrifugal Pumps
• Reciprocating Pumps: Pulsations

3.Pulsation Considerations

• Pulsation Resonance
• Pulsation Dampener
• Cavitation

4.Mechanical Considerations

• Piping Layout
• Clamps
• Pipe Supports

5.Case Studies
6.Conclusion

Key Points

1. Differences exist between centrifugal & reciprocating pumps, and their behavior while interacting with the piping system
2. Reciprocating pumps have many additional piping design considerations, not needed for centrifugal     
3. Pulsation must be considered in recip pump piping design
4. Mechanical piping supports must be considered
5. Small bore piping vibration must be considered in the design stage
6. Reciprocating pumps can work well, if they are designed well!
