Formula: S
Sp. Gr.: 1.8
Viscosity: In the suggested handling range of 121°C / 250°F to 154°C / 310°F, viscosity varies from 9 cPs. to 6 cPs. Above 154°C / 310°F, the viscosity increases rapidly as the temperature increases until at 188°C / 370°F it is almost solid.
Remarks: Sulfur is mined as the pure element in areas of Texas, Louisiana and Sicily. It is also found combined in many ores, petroleum and natural gas. It is used in making sulfuric acid, in the pulp and paper industry, in making carbon disulfide and other chemicals and dyes, for vulcanizing rubber and in medicines. Some sulfur contains abrasive impurities; sulfur should be considered a non-lubricating liquid.
Pump Notes: Cast iron construction is satisfactory. VitonŽ elastomers are acceptable. Special attention must be paid to shaft sealing because of the liquid properties.
