Mechanical Shaft Seals
Thermosyphon Vessel
7.5 litre barrier fluid vessel with cooling coil, level gauge and hand pump for double seals.
Description
A 7.5 litre barrier fluid vessel that circulates and cools the buffer fluid supplied to a double mechanical seal. Maximum working temperature is 180°C and the cooling coil offers a 0.3m² heat transfer area.
Accessories comprise a pressure gauge for measuring vessel pressure, a level gauge to indicate liquid level, and a hand pump for recharging the vessel with additional barrier fluid while the thermosyphon is under pressure and the liquid level is low.
