Main Causes of Impeller Detachment in Polypropylene Ring-Pipe Axial Flow Pumps, Monitoring and Analysis, and Preventive Measures
Bro, the question you raised is really ** absurd. In reality, there are such strange things and such careless people: lol :@ :P
It’s possible; I’ve seen the cap come off twice. However, our technical staff and operators are competent and manage to detect it in a timely manner.
It should be a Sulzer pump; it’s possible that the motor is running in reverse, the shaft and impeller locking mechanism isn’t properly secured, or it could be due to backflow of material causing the impeller to rotate in reverse.
