<p>A seal support system 1 comprises a vessel 3, which contains a barrier/buffer fluid (13 in Fig. 3), connected to a mechanical seal 2 by a feed pipe 4 and a return pipe 5 and the appropriate pipe connectors 6, 7, 8, 9. The seal support system 1 automatically compensates for increased or decreased heat in the vessel 3 via a valving arrangement. The valving arrangement can take the form of either a ball-cock mechanism as illustrated in Figs. 2 and 3, a thermostatic valve and fluid regulator valve combination as illustrated in Fig. 7 or a thermostatic valve, fluid regulator valve and flow fuse valve combination as illustrated in Fig. 8.</p> |
