Seal Proof thermosyphon vessel — upright barrier fluid pot with level gauge, pressure gauge and coil connections.

Overview

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.

Hyd. test pressure
30 kg/cm² provisionalPublished as "30 Kg". The area basis was dropped. kg/cm² is the unit used elsewhere on the same page (the pressure gauge is scaled 0–40 kg/cm²), and a test pressure of 1.5× the working pressure is the normal relationship. Provisional pending confirmation by Seal Proof Engineering.
Working pressure
20 kg/cm² provisionalPublished as "20 Kg". The area basis was dropped. kg/cm² is the unit used elsewhere on the same page, and 20 sits within the vessel's own 0–40 kg/cm² gauge range. Provisional pending confirmation by Seal Proof Engineering.

Connection sizes
Buffer fluid inlet A ½" NPT · Buffer fluid outlet B ½" NPT · Cooling water inlet C ½" NPT · Cooling water outlet D ½" NPT · Hand pump connection E ¼" NPT · Filling connection F 1 ¼" NPT · Pressure gas connection G ½" NPT · Pressure gauge connection H 3/8" NPT · Drain I ½" NPT · Safety valve connection J ½" NPT provisionalPublished as "…outlet B ½ NPT … hand pump connection E ¼: NPT…". Outlet B lost its inch mark and connection E carries a stray colon where the inch mark belongs. Every other port on the same list is written with the inch mark, so both are typographic damage rather than different sizes. Provisional pending confirmation by Seal Proof Engineering.
