The structural characteristics of JG328 series cartridge type mechanical seal are similar to JG318 series. JG328 series is designed with flushing opening, double sealing face. It is suitable for working circumstances where the system pressure quickly increases or decreases due to the back-to-back strulture. JG328 series seals is suitable for hazardous medium and medium which can easily solidify or vaporize. The JG328 double sealing face with bearing can effectively control the vibration and shaking of the equipment.

Operating Limited:

Shaft diameter	25~120mm
Pressure	up to 4Mpa
Temperature	-40~220°C
Slidingvelocity	25m/s

Material:

Rotary Ring	Car / SIC/TC/Cer
O-Ring	, EPDM, NBR, AFLAS, Kalrez,PTFE
Spring and Metal Parts	SUS304, SUS316, HAST C
Stationary Ring	Car / SIC /TC/Cer

Advantages:

• Spring unit averted from the product so no sticking and clogging of the springs
• Safe operation (no fractures) because of seal face locking by square pin
• Suitable for pressure reversals
• Operation in vacuum without additional seat locking possible
• No damage of the shaft by a dynamically loaded O-Ring
• Small installation sizes
• Best suitable for conversions, no adaptations of the pump
• Insensitive to solid containing and abrasive media
• Advantages of a balanced seal even with plain shafts
• Insensitive to shaft movements because of the stationary design

Application:

• Water and waste water technology
• Chemical industry
• Refining technology
• Dirty, abrasive and solid containing media
• Fugitive hydrocarbons (no API seal!)
• Sticky and stringy media
• Chemical standard pumps
• Sewage pumps
