Choose a reading path for the job in front of you: identify a replacement, understand the seal support system, or prepare for maintenance. This technical library connects mechanical seal fundamentals with the dimensions, operating records and inspection details needed for a useful engineering discussion.
A familiar model name is a starting point, not a fit confirmation. Compare the full designation, shaft or sleeve diameter, working length, stationary seat and material combination before discussing interchangeability.
Use the John Crane replacement guide or Burgmann replacement guide to navigate the relevant models.
Read the seal arrangement together with its piping. Identify where each connection starts and ends, which fluid it carries, and what pressure or temperature is actually measured. A piping-plan number alone does not describe every operating condition.
Begin with seal and piping-plan fundamentals, then explore the Plan 11 article.
Build a timeline: installation, first start, changes in duty and the first observed leakage. Keep photographs and measurements with the equipment reference so the inspection can be compared with the original service conditions.
Read the mechanical seal maintenance article and use the preparation checklist below.
That dimension may help identify a shaft size, but it does not confirm the seat fit, working length, drive arrangement or compatibility with the pumped liquid. A useful enquiry pairs the marking with a dimensioned sketch and operating data rather than asking for a match from a photograph alone.
Start with what a mechanical seal is, then read pump mechanical seal technology. Return to the relevant reading path when you have a specific replacement or maintenance question.
These articles support preparation and discussion. Equipment-specific drawings and approved isolation, installation and commissioning procedures govern the work. For a product enquiry, contact Fluid Tech Service with the available measurements and duty details.
The article list below brings together the library's replacement, design and maintenance topics.
History of flowserve seal The former name of Flowserve corporation is Simpson & Thompson, which was been found in 1790 by Thomas Simpson. Later to

What is mechanical seal ? Mechanical seals is a device used in rotating equipment. I.E. centrifugal pump, agitator, compressor etc. When above equipment running, there
Pump mechanical seal technology has three points i will share in this article. At first part, It will be pump mechanical seal definition. In this
API Plan 11 recirculates pump discharge liquid to the seal chamber. Learn how the orifice and available pressure difference affect flushing, with a worked comparison, maintenance checks and answers to common selection questions.
A mechanical seal controls leakage where a rotating shaft passes through a pump housing. Learn how its parts work together, then use practical leak-observation and replacement checks to prepare a more useful service enquiry.
After we running mechanical seal for a long time or have a long storage, we should consider about maintenance,repair or overhaul of mechanical seal. In this article we will shortly introduce steps how you can do it professionally.
