Scope of Application
Weak corrosion medium, without strict requirements for seal
leakage. Need clean liquid, such as oil or water in the lubrication
box. (202 can bear some suction pressure)
Applied in various conditions without lubricating liquid, such as
fermentation tank, mycotic tank, reaction tank, etc.
Half stationary ring type. Used for large shaft diameter.
Stationary ring can be changed without unloading reducer. Others
are the same as 202F, 204F.
Dry-milling type. Applied for various conditions without
lubricating liquid. GW204H has fragments well. It can isolate the
fragments and can prevent pollution to the medium in the tank. The
overflow port can be washed with clean liquid routinely.
Weak corrosion medium, with strict requirements for seal leakage.
Applied for inflammable, explosive, hazardous, and high vacuum
conditions. Use hard to hard pair, and can applied to the
conditions with solids.
With two inner cone bearing or angle touch bearing, and can be set
as one support point for the shaft. Can be designed as the
structure with short shaft.
The seal has waste fluid collector, and can prevent pollution the
tank medium. The overflow port can be washed with clean liquid
Can used in the tank temperature ≤350. Other applying conditions
are the same as 205,206,207.
For various weak corrosion medium, especially for side-entry
Applied to corrosion, liquid(except HF) without solid and low
requirement for leakage conditions, especially for glass lining
tank, titanium alloy tank, and the conditions with vacuum need and
large radial oscillation.
Applied to strong corrosion medium, and low leakage conditions. Can
be used to glass lining and titanium alloy tank.
Applied to strong corrosion medium, and low leakage conditions.
Usually used for stainless tank.
285, 286, 288
Determine the material and applied condition according to medium.
Usually for weak corrosion medium, bottom-entry or side-entry,
strict seal requirement conditions. With T and change the stuffing
seal to single face seal, can be used in the conditions with solids
Applied to weak corrosion medium, common seal requirement
conditions. 2002 type can guarantee rotation precision well.
Applied to weak corrosion, strict requirement to leakage
