WebPlan 52 Working Principle In a dual un-pressurized (tandem) arrangement, two seals are used. The primary seal operates in the process liquid at seal chamber pressure. Cooling and lubrication of this seal is achieved by use of any of the API flush Plans 11-41. The secondary seal operates in a buffer liquid at a pressure WebAPI 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. Frictional losses in the buffer fluid inlet and outlet lines should be minimized by selecting the proper tube size ...
WebOrifice size should be at least 3 mm (1/8"). The flow of the flush fluid must be sufficient to remove the heat from the mechanical seal chamber. Calculate the orifice size and the throat bushing clearance carefully to ensure the desired flush flow-rate. Do not use in case the difference between seal chamber pressure and suction pressure is very ... WebDesigned for piping plans 52 and 53A, the 682R series buffer/barrier fluid reservoir provides an ideal supply of clean, cool and reliable working fluid to maximize dual mechanical seal life and reliability.

In this arrangement, a reservoir is connected to the containment seal drain port on the gland. Condensed leakage from the inner seal is collected in the reservoir while vapor is routed …
WebAn API Plan 53A/ANSI Plan 7353A is usually chosen over an API Plan 52/ ANSI Plan 7352 for dirty, abrasive or polymerizing products which would either damage the seal faces or cause problems with the barrier fluid system if an API Plan 52/ ANSI Plan 7352 is used. There are two disadvantages to an API Plan 53A/ANSI Plan 7353A which must be ... agni vayu afcat log inWebFeb 8, 2024 · The seal cooler primarily removes heat entering the seal chamber from seal generated heat and heat soak through the pump casing.

Ensure that the barrier pressure is always higher than the seal chamber pressure by at least 1.4 bar (20 PSI). For barrier pressures above 16 bar (232 PSI) use Plan 53B, 53C or 54. Check with the process engineer if product contamination is acceptable. agnitundi vatiWebCaution. 1. Keep pot vent continuously open, which is necessary to maintain buffer fluid pressure close to atmospheric pressure and vent the vapors to flare. 2. Should not be used with dirty or polymerizing products. 3.
