FAQ

What do the material codes BQ1VMG signify for this Cartex-SE seal?

BQ1VMG is a standard EagleBurgmann material code. ‘B’ typically refers to Carbon graphite antimony impregnated (for the stationary seat), ‘Q1’ refers to Silicon carbide (for the rotating face), and ‘VMG’ specifies FKM (Viton) for the O-rings and secondary seals, suitable for a wide range of chemicals and temperatures.

What is the purpose of the 3/8 NPT ‘FLUSH’ connection on the seal gland?

The flush connection is used to introduce a clean, external fluid (a ‘flush’) into the seal chamber. This serves to cool the seal faces, lubricate them, and prevent the process fluid from crystallizing or building up around the seal, thereby extending its service life, especially in demanding applications.

Is this cartridge seal pre-set for installation, and what care should be taken during fitting?

Yes, all EagleBurgmann Cartex seals are pre-assembled and pre-set in the factory. Installation involves sliding the cartridge onto the shaft and securing it. It is crucial to ensure the shaft and seal chamber are clean and free of burrs. The blue spacer clips seen in the image must only be removed after the gland plate is fully bolted down and the grub screws on the collar are tightened.
