Mechanical Face Seals DF also known as Biconical Seals

Product Advantages:

Mechanical end seals or heavy-duty seals are designed for rotary applications in extremely harsh environments where they can withstand very severe wear and prevent entry of abrasive external media. Mechanical end seals are known as heavy-duty seals, end seals, floating seals, life seals, Toric seals, and multi-cone seals.

Product Introduction

TECHNICAL DRAWING

Mechanical face seals DF has an elastomer with a diamond-shaped cross section as a secondary sealing element instead of the O-Ring.

Mechanical face seals DF consist of two identical metal seal rings mounted in two separate housings face-to-face on a lapped seal face. The metal rings are centered within their housings by an elastomer element. One half of the Mechanical Face Seal remains static in the housing, while the other half rotates with its counter face.

Product Applications

Mechanical end seals are used to seal the bearings of construction machinery in production plants that operate under very harsh conditions and resist severe wear and tear.

These include:

Crawler vehicles such as bulldozers and excavators
Shaft
Conveyer system
Heavy trucks
Tunnel drilling machine
Mining machinery
Agricultural machinery
Mechanical face seals are proven to be suitable for applications in gear boxes, stirrers, wind power plants and other similar conditions, or where minimal maintenance levels are required.

How to choose the right oil for the floating oil seal

“The sealing of the floating oil seal is maintained by the ultra-thin oil film generated between the contact surfaces, so it is necessary to apply lubricating oil in the floating oil seal. However, improper lubricating oil types or methods will cause chemical compatible reactions between the rubber ring and the oil, resulting in floating density.”

The sealing of the floating oil seal is maintained by the ultra-thin oil film generated between the contact surfaces, so it is necessary to apply lubricating oil in the floating oil seal. However, the improper type or method of lubricating oil will cause chemical compatibility between the rubber ring and the oil, resulting in early failure of the floating seal. Some greases can be used in some cases of slow speed and low vibration, but liquid synthetic oil should still be used as a **. In order to lubricate and cool the floating oil seal well, the lubricating oil must cover 2/3 of the sealing surface. Try to ensure the cleanliness of the oil and sealing system to prevent the loss of the floating oil seal life. Some oils are not compatible with artificial rubber, especially under high temperature conditions, and long-term contact will lead to aging. Therefore, compatibility tests should be done between rubber rings and oil products before oil injection.
