SRVB #11-Preparation and Verification of All Pressure Boundary Flanges on HT Boiler Water Circulating Pumps (BWCP): New Manufacture or Repairs
This Safety Bulletin is in response to customers asking about the suitability of hardware on connection flanges after return from shop service or upon initial receipt of a new motor. The below information serves as guidance about what needs to be
SRVB #8-Boiler Water Circulating Pump-Motor Rotation Verification
This procedure should be viewed as guidance to give the owner advice in verifying that the motor is operating in the correct rotation. It is not a guarantee of the correct rotation, as, at all times, good judgment must be utilized. It is very
Advantages of using a Canned Motor Pump (Sealless Pumps)
Canned motor pumps (a type of sealless pump) are widely considered the safest and most reliable pumping solution. The biggest benefit of a Canned Motor Pump is that there is no mechanical seal that leaks to the atmosphere. Instead of using a
SRVB #5-HT BWCP rotor to stator magnetic gap restack criteria
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
