Heavy Duty Type Do Mechanical Face Seals Floating Oil Seals

CZPT Experience Seals are a specific type of mechanical seals. They are also known beneath other designations, this sort of as life span seals, floating seals, duo cone seals, toric seals and large duty seals.

There are two different sorts of CZPT Face Seals: the most typical kind is Type DO, which is characterized by the use of an O-Ring as the CZPTary sealing element (Determine one).

Kind DF, on the other hand, has an elastomer with a diamond-shaped cross segment as a CZPTary sealing aspect instead of the O-Ring (Figure 2).

Equally kinds consist of two identical steel seal rings which seal towards every other on a lapped seal confront.
The DO profile is a CZPT floating seal or confront seal composed of two metallic components manufactured from 18Cr or 15CrMo Or 15CrMo3Ni Alloy Forged Iron seal and two rubber O’Rings.

Kinds of lubrication

For the program to operate correctly, it is essential to lubricate the seal at the sealing gaps. We suggest utilizing oil lubrication rather than grease lubrication.

  • For an oil lubrication that is long term and does not demand repairs, the oil degree need to be among the 2/three of the within diameter of the seal and the center of the axis. We recommend utilizing SAE 80 and SAE ninety gearbox oils for a greater operation.
  • Grease lubrication requires specific consideration. It is prevented due to the hydrodynamic conditions of lubrication that can not be met, which could guide to substantial wear and for that reason a untimely deterioration of the seal. If grease lubrication is utilized, the grease need to not be inserted among the friction surfaces of the seal.
