Non-Contacting Gas Lubricated Mechanical Seal

Effective containment of VOC emissions and contamination prevention of high value products.

Non-contacting, gas lift dual cartridge seal primarily designed for pumps (ANSI/DIN) providing practically zero process emissions in service.

The non-contacting nature of the design ensures long life, low power consumption and reduced capital cost for support systems. The buffer/barrier gas should be readily available and inert e.g. dry Nitrogen. One other major benefit is the ability to prevent contamination of high value products.

Features:

• Non-contacting spiral groove face technology
• Long life with low power consumption
• Externally mounted and suitable for ISO 5199 and ANSI pumps
• Can be adapted to fit other types of rotating equipment
• Zero process emissions
• Low running costs

TYPICAL DUTIES:
