This is double cartridge seal, equivalent to The DEPAC mechanical seal type 321 is a stationary single-cartridge seal with a round gland
that is extremely well suited for conversions from gland packing to mechanical seal, since
modification of the unit is not usually necessary. The stationary design principle developed
by DEPAC for the process industry also offers maximum running reliability even in difficult
ranges of applications for mechanical seals.
Advantages
• Stationary design principle
• Ideal for conversions from gland packings to mechanical seals
• Extremely well suited for standardisations
• Cartridge-mounted
• Pressure balanced
• Independent of the direction of rotation
• Multiple springs made of Hastelloy C
• Springs outside the medium – no blockage of the springs
• Vibration-damped rotating face
