On Jan 28, 2017, a common myth was debunked regarding the effect of reverse rotation on a centrifugal pump. There is a misconception that in reverse rotation, the pump causes backward flow, with the discharge going in and the suction coming out. However, the reality is quite different. When a pump operates in reverse rotation due to wiring issues or a phase change, it will pump in a different manner.

Centrifugal Pump Reverse Rotation
Reverse rotation of a centrifugal pump occurs when the motor driving the pump rotates in the opposite direction than intended. This can happen due to incorrect wiring, a phase change, or other mechanical issues. When a centrifugal pump operates in reverse rotation, it can lead to various problems and inefficiencies.
Reverse Rotation of Pump
The reverse rotation of a pump can have detrimental effects on its performance. It can cause increased wear and tear on the pump components, leading to decreased efficiency and potential breakdowns. Additionally, reverse rotation can disrupt the flow of the fluid being pumped, affecting the overall system operation.
Reverse Direction of Centrifugal Pump
When a centrifugal pump operates in reverse direction, it can result in cavitation, which is the formation of vapor bubbles in the pump due to low pressure. Cavitation can damage the pump impeller and other components, reducing the pump's effectiveness and lifespan. It is essential to address reverse rotation promptly to prevent these issues.
Reverse Rotation Pump Problems
Some common problems associated with reverse rotation of a centrifugal pump include increased vibration, reduced flow rate, decreased efficiency, and potential damage to pump components. These issues can lead to costly repairs and downtime, impacting the overall operation of the system.
Centrifugal Pump Reversing
Centrifugal pump reversing refers to the process of correcting the rotation direction of the pump to ensure proper operation. This may involve rewiring the motor, adjusting the phase sequence, or making mechanical adjustments to the pump assembly. It is crucial to address centrifugal pump reversing promptly to avoid further complications.
Centrifugal Pump Reversing Angle
The reversing angle of a centrifugal pump refers to the angle at which the pump impeller rotates in the reverse direction. This angle can impact the pump's performance and efficiency, as well as the potential for cavitation and other issues. Properly adjusting the reversing angle is essential to maintain the pump's optimal operation.
When rotating in reverse, the fluid encounters these blades at angles they are not designed for. This creates uneven forces acting on different parts of each blade. Difficult to …
