Warman S51 Viton Slurry Pump Rubber Seals

Warman Slurry Pump S51 material is a kind of Fluoroelastomer (Viton), S51 slurry pump seals have exceptional resistance to oils and chemicals at elevated temperatures. Limited erosion resistance.

Viton is a brand of FKM, a synthetic rubber and fluoropolymer elastomer commonly used in slurry pump O-rings, slurry pump seals, chemical-resistant gloves, and other molded or extruded goods.

Viton fluoroelastomers are categorized under the ASTM D1418 and ISO 1629 designation of FKM. This class of elastomers is a family comprising copolymers of hexafluoropropylene (HFP) and vinylidene fluoride (VDF or VF2), terpolymers of tetrafluoroethylene (TFE), vinylidene fluoride (VDF) and hexafluoropropylene (HFP) as well as perfluoromethylvinylether (PMVE) containing specialties. The fluorine content of the most common Viton grades varies between 66 and 70%.

While Viton can be sometimes distinguished from other types of rubber by its often green or brown colour, a more reliable test is its density of over 1,800 kg/m3, significantly higher than most types of rubber (1,010-1,520 kg/m3). 

S51 Viton Rubber Seals for Slurry Pumps:

Applications:

The performance of fluoroelastomers in aggressive chemicals depends on the nature of the base polymer and the compounding ingredients used for molding the final products (e.g. O-rings). This performance can vary significantly when end-users purchase Viton polymer containing rubber goods from different sources. Viton is generally compatible with hydrocarbons, but incompatible with ketones such as acetone and methyl ethyl ketone, ester solvents such as ethyl acetate, amines, and organic acids such as acetic acid. O-rings made of Viton are typically color-coded as black, but new gaskets, seals and O-rings should be green FKM or black FKM, but with a green mark on the outer edge.
