What is API plan 53B?
API Plan 53B circulates a pressurized barrier fluid between the inboard and outboard seals. The source of pressurization is a bladder accumulator. Plan 53B has the advantage of not allowing gas absorption into the barrier fluid which may allow for operation at higher pressures than Plan 53A.
What is API plan for pumps?
These are standardized flushing piping arrangements that are widely used in the industry. Customer specific variants of these plans are possible. API Piping plans help to ensure good conditions for mechanical seal operation as well as improving safety and pump reliability.
What is API flushing plan?
Description: Process side API seal flush plans use a single mechanical seal to prevent pump (process) fluid from leaking. In this arrangement, the process fluid is the lubricant. It provides a thin film between the seal faces to reduce friction and absorb heat.
What is Plan in mechanical seal?
A flush plan is a strategic equipment arrangement that circulates fluid to or from the seal chamber in order to maintain proper lubrication, pressure, temperature, and solids management. The goal is to create an ideal work environment for the seal in order to avoid wear and failures, thus prolonging its useful life.
How does plan 52 work?
API Plan 52 seal systems employ a seal pot (reservoir) to deliver an unpressurized buffer fluid to the seal chamber and circulate the fluid between the inboard and outboard mechanical seals. A pumping ring is utilized to provide positive circulation through the seal flush system and into the seal.
How does the seal 52 plan work?
API Seal Plan 52 utilizes a reservoir and circulates an unpressurized buffer fluid between the inboard and outboard seals. To provide positive circulation through the support system and into the seal, a pumping ring is employed.
Is there an API for plan 53B?
API Plan 53B. The AESSEAL ® Seal Auxiliary Systems Division has established a pioneering method of developing API Plan 53B Systems. Plan 53B systems have been viewed as an “engineering challenge” around the world, often with long lead times.
Why choose AESSEAL® API 53B systems?
This modular process facilitates efficient stock control which in turn provides AESSEAL® API 53B Systems with rapid delivery times. Modularity eases the production of documentation for each Plan 53B product and also makes it easier to determine the correct solution for the application.
How does a plan 53A system work?
The barrier fluid and nitrogen are separated by a bladder which effectively prevents the nitrogen from mixing with the barrier fluid as in the case of a Plan 53A. The pumped medium generally does not leak to the atmosphere unless the bladder pressure is lost.
