API Plans

Integrated (internal) product recirculation from pump discharge to seal chamber.

Dead ended seal chamber with no flush fluid circulation.

Product recirculation from pump discharge to seal through a flow control orifice.

Product recirculation from pump discharge through a Y strainer and a flow control orifice to seal chamber.

Product recirculation from seal chamber to pump suction via a flow control orifice.

Product recirculation from pump discharge to seal chamber through a flow control orifice and seal chamber back to suction through another flow control orifice.

Product recirculation from discharge through flow control orifice and heat exchanger to seal chamber.

Product recirculation from seal chamber to heat exchanger and back to seal chamber.

Product recirculation from discharge through a cyclone separator, which directs clean fluid to the seal and solids back to pump suction.

Injection of clean or cool liquid from external source into the seal chamber.

Product recirculation from discharge through a cyclone separator and a heat exchanger to seal chamber.

External reservoir providing a dead-ended blanket for fluid to the quench connection of the gland.

Depressurised buffer fluid circulation in outboard seal of a dual seal configuration through a seal support system. Circulation is maintained by using pumping ring in running condition and by thermosyphon effect in stand still condition.

Pressurised barrier fluid circulation in outboard seal of dual seal configuration through a seal support system. Circulation is maintained by using pumping ring in running condition and with thermosyphon effect in stand still condition.

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.

Pressurised barrier fluid circulation in outboard seal of dual seal configuration. Circulation is maintained by using pumping ring in running condition and with thermosyphon effect in stand still condition.

Pressurised external barrier fluid circulation from a central pressure source or by a stand alone pumping unit (e.g. AESSEAL PUMPPAC™).

Plugged connections for future use for Plan 62 or Plan 65.

An external fluid stream is brought to atmospheric side of the seal faces using quench and drain connections.

Leakage from seal faces is directed to a liquid collection system. A vessel with a high level alarm is provided for detection of excess leakage.

Plugged connections for future provision to supply a buffer gas to a dual containment seal.

Buffer gas is passed through the containment seal chamber to sweep inner seal leakage away from outer seal to a collection system and / or dilute the leakage.

Externally pressurised barrier gas supplied through a gas control system to a dual seal arrangement. An inert gas is used as a barrier gas.

Leakage of condensate from inboard seal of a dual containment seal is directed to a liquid collector.

Vapour leakages from inboard seal of dual containment seal are directed to a vapour recovery system via a vent connection.
