What is API plan 62?
API Plan 62 delivers an external quench fluid to the atmospheric side of the seal. A typical application in a refinery is the prevention of coking on seal faces in hot hydrocarbon service by employing a steam quench. Nitrogen or clean water may also be used to quench or cool and clean the atmospheric side of the seal.
What are API plans?
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 plan 32?
API Plan 32 delivers a clean flush fluid into the seal chamber from an external source. Typically used with a close-clearance throat bushing, this arrangement can be used to ensure a higher pressure in the seal chamber.
What is API plan 53A?
API Plan 53A utilizes a reservoir and circulates a pressurized barrier fluid between the inboard and outboard seals. The typical source of pressurization is plant nitrogen. The reservoir should be set at least 20 psi (1.3 bar) above maximum seal chamber pressure.
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. API Plan 11. Kit components shown solid and include some optional components.
What is API plan 23?
API Plan 23 utilizes a circulation device, typically a pumping ring, to route the fluid from the seal chamber through a cooler before returning the cooled fluid to the seal chamber. A throat bushing isolates the cooled seal chamber flush fluid from the hotter pumped liquid.
What is the difference between Plan 53A and 53B?
The major difference in the plans is that Plan 53A uses an external reservoir, while Plans 53B and 53C run within a closed loop system with a make-up system piped to it for replenishment of the barrier fluid.
What is an API 610 pump?
An API 610 BB pump is a “Between-bearings” pump where the impeller is mounted on a shaft with the bearings at both ends so the impeller is mounted between bearings. For all BB pumps the impeller is mounted horizontally. Type. Casing. Impeller.
What is a flush plan?
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.
What is API seal 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 in pump?
API Pump Type Definitions | Understanding API Standards. API (American Petroleum Institute) is a set of standards used to define systems, tests, and equipment design, mainly in the Oil & Gas industry. There are other standards, such as ISO, ASME, NEMA, or ANSI.
What is API plan for pumps?
API Plan 55 is a custom-engineered system. It delivers cool, clean unpressurized buffer fluid to the cavity between the inboard and outboard seals using a pump located on an external reservoir. The plan can be configured with filters, coolers, and other instrumentation and components to meet process requirements.
