How is the chamber pressure at the mechanical seal of a centrifugal pump determined? :handshake
Pumps with different structures vary greatly; for single-stage cantilever pumps equipped with balance holes or auxiliary impellers, the empirical formula is 1/3 of the outlet pressure plus the inlet pressure. It is best to conduct actual measurements, as this pressure depends greatly on the distance from the mouth ring.
