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?
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 the time between 53B refills called?
Although the concept of Plan 53B as described in API 682 is based on a refill interval of 28 days (and therefore a wide operating pressure range), some variations of Plan 53B are designed to have a smaller operating pressure range and therefore require frequent refill.
What is API plan 54?
API Plan 54 is a custom engineered system that delivers a pressurized barrier fluid to the seal chamber. The barrier liquid is circulated to and from the seal chamber via a pump located on an external reservoir. This fluid is maintained at a pressure greater than that found in the seal chamber.
What is API seal plan?
This plan is a combination of Plan 11 and Plan 13 where process fluid is recirculated from the pump discharge through a control orifice, and from the seal chamber through a flow control orifice to the pump suction. Pros: Optimizes cooling and seal chamber venting. Flush is targeted directly at seal faces.
What is API plan 61?
Position: Atmosphere side. Description: The connections on the atmosphere side of the seal are provided but plugged with metal plugs or connected to the leakage collection system.
What is api610?
API 610 is a pump standard for centrifugal pumps in the petroleum, petrochemical, and natural gas industries. API, an acronym for the American Petroleum Institute, is an organization that develops technical standards for oil and natural gas industries. API 610 is the centrifugal pump standard put forward by API.
What is API plan 11?
API Plan 11 recirculates flow from a high‐pressure section of the pump, typically the discharge piping, through a flow control orifice to the seal. Plan 11 is the default flush plan for most pumps.
What is api676?
API 676 is the API standard for rotary, positive displacement pumps. The standard provides design criteria for all types of rotary PD pumps.
What is difference between OH & BB pump?
OH – Overhung pumps – The impellers of these pumps protrude from the bearings. The impellers of these pumps can be mounted either horizontally or vertically. BB – Between bearing pumps – The impellers of BB pumps are suspended in between the supports.
Is there such a thing as an API 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.
Which is plan 53B system does AESSEAL use?
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. The innovative modular concept permits 12 modular options to be applied to create an API 53B System for any application.
Is the plan 53B system an engineering challenge?
Plan 53B systems have been viewed as an “engineering challenge” around the world, often with long lead times. The innovative modular concept permits 12 modular options to be applied to create an API 53B System for any application.
What to know about mechanical seal flush API Plan 53B?
In colder climates where a plan 53B is installed outside, the system should be properly heat traced and winterized. This includes the seal flush piping, the accumulator and the exchangers. The accumulator contains a nitrogen bladder with a pre-charge pressure as previously indicated.
