Chemically Inert Materials In All Areas and On All Surfaces – IS20 – 20R

Types IS20 and 20R shaft seals feature chemically inert materials in all areas and on all surfaces in contact with the liquid being sealed. Metallic components, springs and clamp ring are located outside the pump seal chamber, isolated from the process liquid.

For use with extremely corrosive chemicals, including concentrated acids and salts, strong oxidizing and reducing agents, and chemically active organic compounds commonly used on PTFE filled pumps.

The entire seal assembly and component parts employ mechanical drive to prevent slippage on the shaft or sleeve. Seal assembly is outside mounted and internally pressurized.

Product Description IS20 – 20R

IS20 and IS20R shaft seals feature chemically inert materials in all areas and on all surfaces in contact with the liquid being sealed. Metallic components, springs and clamp ring, are located outside the pump seal chamber, isolated from the process liquid. Multiple springs are standard. A single spring design is available.

For use with extremely corrosive chemicals, including concentrated acids and salts, strong oxidizing and reducing agents, and chemically active organic compounds commonly used on PTFE filled pumps

California Residents: PROPOSITION 65 WARNING
Maximum corrosion resistance.
Eliminates possibility of seal face misalignment.
Compensates for shaft runout to promote low maintenance, long-life operation.
Independent spring assembly
Replaceable primary ring (Type 20R) provides uniform face loading characteristics.
Easy removal and replacement of sealing member most subject to wear.
