General-duty Elastomer Bellows Shaft Seal
Our general-purpose Type 21 mechanical seal has become the industry standard for OEM designers.
Automatic adjustment compensates for abnormal shaft-end play, run-out, primary ring wear and equipment tolerances.
The Type 21 is ideal for use in centrifugal, rotary and turbine pumps, compressors, chillers and other rotary shaft equipment. It is also commonly used by the wastewater and water systems industries for applications such as waste treatment, potable water and HVAC.
