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.

Emulsions are asphalt suspended in a mixture with water or other liquids. This is done to ease the application of the asphalt. Uses would be crack filling, coating roadways, or waterproofing. These emulsions are shear sensitive and must be handled with care.

Machinery lubrication pumps are used in everything from small backup generators to naval ships. Lube oils, as the name implies, are the liquids used to lubricate rotating and reciprocating machinery. Lube oils may be handled at higher pressures to ensure their penetration of the equipment.

Also known as TDI, MDI, or diisocyanate. Isocyanate is used as a hardening or curing agent in polyurethane foams, industrial coatings, elastomers, inks, and resins. It is extremely sensitive to moisture in the air and hydrocarbons making air-tight seal options extremely critical.

Polyurethane foam is produced when a polyether is treated with a isocyanate in the presence of water and a catalyst, as well as fillers, dispersing and emulsifying agents, etc. The water reacts with the isocyanate group to cause cross linking and curing, and also produces carbon dioxide which causes foaming. May also be known as Isocyanate liquid.

Hot cooking oils are used primarily for deep fat frying of vegetables and meats. Some cooking oils or fats will become solid at room temperature, however the pumps are typically located close enough to the supply that it keeps the pump warm. The viscosity is typically water-thin at normal operating temperatures.

This group of oils may consist of olive, palm, soybean, canola, pumpkin seed, corn, sunflower, safflower, peanut, grape seed, sesame, and rice bran or a blend of these oils that is typically referred to as vegetable oil.

Reclaimed Asphalt is typically a dirty or filled asphalt containing a bitumen blend with solids that could be limestone or rubber based. These solids result in very high viscosities and abrasive nature, resulting in the need for extra clearances, low run speeds, and the inclusion of hardened parts.

Resins are high viscosity liquids with potentially shear sensitive (thinning) components, and made up of solvents, waxes, surfactants, and semi-solid resin particles all with various chemical compatibility concerns. These resins can be used in polyurethanes, epoxies and other adhesives. In some cases, resins contain pigments that bring with them abrasive wear concerns.
