The pump of KSB suddenly experienced a shaft breakage during operation; there were no abnormalities in current, flow rate, pressure, or vibration at that time, and the end faces of the shaft were still in good condition. Could anyone give some advice?

After the equipment’s pipes come into operation, the force resulting from thermal expansion can cause bending moments on the shaft, affecting its lifespan; even if everything was proper during installation, this force can still act on the shaft.
