Product Description

Depac Double-Acting Cartridge Mechanical Seal Type 321 322 323 326 365 API Mechanical Seals 380 385 Agitator Seals Type 370 Metal Bellow Seals Type 201 170 186 196

Mechanical seal Types 321, 322 and 323:

The types 321, 322 and 323 are stationary, tandem-active double cartridge mechanical seals with integrated barrier fluid pumping assistance. The double pressure balancing of the seal faces on the product side ensures one the one hand that the seal faces do not open in case of pressure reversal. and on the other that the balancing for reducing the friction values is present under all pressure conditions.

The respective product versions differ by their seal chamber cross-sections.

• Self-closing in case of pressure reversal
• Venting option

Agitator cartridges types 370 to 373:

DEPAC has four optimised mechanical seals for the challenging boundary conditions of an agitator. The advantage: the flange and face parts as well as certain seal housing parts are exchangeable. The operator's stock can thus be kept to a low level and a wide range of replacement parts is available.

Type 370
Double mechanical seal with bearing
DIN 28141 flange
DIN 28154 shaft form A - B - C or according to all other standard specifications or customer requirements
Type 371
Single mechanical seal with bearing
Type 372
Double mechanical seal
Type 373
Single mechanical seal

• DIN dimensions, alternatives are possible
• Shock and vibration-dampend faces
• Double balanced
• Full pressure reversability
• Self-closing in case of pressure reversal
• Mirror-image face design
• Independent of the direction of rotation

Mechanical seal Type 201:

 

The type 201 is a stationary, balanced mechanical seal. The mechanical seal is designed for demanding ranges of applications, including hot water and chemical applications. The type 201 seals reliably at temperatures of up to 240 degrees Celsius and a pressure of 20 bar. DEPAC recommends spot-drilling the shafts or sleeves for set screw fastening at pressure loads exceeding 10 bar.

• Stationary mechanical seal design principle
• No scoring of pump shafts/sleeves
• Balanced

Mechanical seal Type 196:

 

The DEPAC type 196 is a stationary, balanced, single-component seal that was specially developed for installation spaces according to DIN 24960 / EN12756. The stationary design guarantees the best possible running smoothness and entirely rules out scoring of the shaft. The balancing results in lower face friction and thus less wear, which is reflected by an optimisation of the service life.
DEPAC also offers these mechanical seals in larger sizes than the standard sizes indicated in the standard. The mechanical seal can be combined with popular retainers, glands and adapter parts.

• Stationary design principle
• No scoring of the shaft or shaft sleeve
• Fits installation spaces according to DIN 24960 / EN12756
• Balanced
• Independent of the direction of rotation
• Multiple springs made of Hastelloy C
