Crude Oils
This is a very generic term for unrefined oils typically being recovered from the ground. Some crude oil may contain particulates from the oil well or recovery method. They are considered to be flammable liquids. Crude oils are later refined and used for everything from making plastics to gasoline.
Diesel (#2 Fuel Oil)
Diesel is distilled from petroleum and is typically used in heavy equipment as fuel. While it is thin diesel is somewhat lubricating. It is typically handled in a bulk transfer application or on back-up generator skids.
Lube Oil Blending
Local blending plants take bulk petroleum or synthetic base oils and mix them together with additives to create unique oil blends for specific applications and customers.
Asphalt Cement
Clean asphalt contains no fillers and is an oil based liquid. It is primarily used in paving roads, waterproofing liquids, and paints. Typically they are handled at elevated temperatures to reduce the viscosity of the asphalt. The pump needs a source of heat like jacketing or electric heat to prevent the product from solidifying in the pump.
Rubber Cement
Rubber cement, also referred to as contact cement covers a wide range of materials; some may be emulsions sensitive to shearing; others may be flammable because of the solvent carrier; others may be water solutions, which are used in a variety of adhesive-type applications. Due to the variance in material and solvent used, the viscosity varies greatly.
