Piping systems that utilize positive displacement (PD) pumps come with a unique set of challenges. One challenge is pulsation as a result of the cyclic nature of PD pump operation which can cause high vibration, fatigue failures, frequent maintenance outages, and flow uniformity or product quality problems.
Purple Mountain can provide the following consulting services based on our experience with the AFT Impulse Pulsation Frequency Analysis (PFA) module:
- Prediction of resonant frequencies in your system as a result of the PD pumps so they can be avoided in operation
- Sizing of pulsation dampeners to change your system’s natural frequency and prevent pulsation issues
- Ensure the pressure pulsation magnitudes comply with the API-674 Standard
