What is the total series capacity for multiple pumps, and what is the half-series capacity? Also, what should be the optimal gap for the balance disc? Thank you for your guidance

Pumps vary from one manufacturer to another, with different models offering distinct features. You can check the technical maintenance documents for the pump; all the information is there
After each baffle bolt is tightened, pull the rotor back and forth without installing a balance disc to determine the total series displacement. After installing the balance disc, it becomes a half-string quantity. Regarding the clearance of the balance disk, the factory says it’s not necessary to leave any clearance, but there is a concern that the balance disk and the balance drum might stick together at the moment the pump starts operating; therefore, a clearance of 0.10 mm is generally reserved, and it should not be too large.
4L provided a very detailed response; for multi-stage pumps with different stages and operating conditions, the overall series requirements vary, so it is best to consult the manufacturer
