At PSS Group, we continue to push the boundaries of engineering excellence with our precision capabilities in pump performance prediction. A recent project with a BB1 pump highlights how our advanced CFD (Computational Fluid Dynamics) simulation technology accurately predicts performance, providing our customers with reliable and efficient solutions.
### The Challenge
A customer required a reverse-engineered 703 mm impeller made of SS316 for a BB1 pump. They needed assurance that the new impeller would meet the original pump’s performance specifications. To confirm this, PSS Group used CFD software to simulate the different flow conditions in the performance curve. We also leveraged in-house 3D scanning and reverse engineering expertise.
### The Solution
We took the following steps to ensure accuracy:
- 3D Scanning and Reverse Engineering : Using cutting-edge scanning equipment, we accurately mapped the geometry of the impeller, allowing us to reverse engineer the component.
- CFD Simulation : To verify performance, we conducted CFD simulations of the pump at three different flow rates: 1,440 m³/hour, 2,160 m³/hour, and 2,592 m³/hour.
### Simulation Accuracy
The CFD simulations were highly accurate, providing near-perfect predictions against the performance curve:
- Head prediction : Accurate within 1.7% to 3.6%
- Brake Horsepower (BHP) prediction : Accurate within 0.62% to 1.15%
- Efficiency prediction : Accurate within 0.73% to 2%
### Confidence in Our Results
These results assured the customer that the new impeller would perform as required, confirming the precision and reliability of our reverse engineering and simulation processes.
At PSS Group, we pride ourselves on providing innovative engineering solutions that meet and exceed our customers’ expectations. Our CFD simulations offer unmatched accuracy, allowing us to guarantee the performance of rotating equipment upgrades.
