What is the maximum pressure rating that a standard single-stage centrifugal pump can achieve? Is this value determined by the pressure resistance capacity of the mechanical seal?
It is determined by the pressure resistance of the casing (pump body, pump cover, and sealing gland), the strength of the bolts used to connect the casing components, the pressure resistance of the static sealing gaskets (seals) between the casing parts, the pressure resistance of the mechanical seal, and the amount of axial force that the rolling bearings can withstand
I’m referring to the weakest link, the component that requires the most attention, its pressure resistance
The pump body need not be the strongest, and the mechanical seal need not be the weakest; a design with equal strength and lifespan is preferable
