There has been much discussion over when to restack a BWCP rotor or stator for electrical performance reasons (i.e. not mechanical damage, but actual or anticipated performance degradation). There are four primary concerns with an increased

SRVB #3-Boiler Circulation Pump Cavitation
As most pump users know, that when cavitation occurs, it is the result of vapor bubbles collapsing within the impeller passages. It may be within the fluid or on the metal surfaces, and most often does cause vibration in the unit. If severe enough,
SRVB #2-Boiler Circulation Pump Vibration
All rotating equipment lends themselves to vibration measurement and analysis. During normal operation they emit a specific vibration signature. If this signature changes it provides an indication of a change in the health of the
SRVB #1-Boiler Water Circulation Pump Protection during Boiler Acid Cleaning
A purge supply of 2 USgpm minimum should be maintained throughout the entire chemical cleaning operation on ALL pumps in situ, regardless of whether the motors are energized or not, unless the pumps can be isolated from the system, and this isolation
