Our application engineers would like to extend their experience in troubleshooting and product alignment to you through our liquids list below. Though this is not a complete listing of the broad range of liquids that Viking pumps can manage, this is an overview of frequent liquids. Do you have a unique application? Reach out to your local stocking distributor. We can work together to find a solution that best suits your pumping needs.

Select Liquid

Acids / Bases

Extremes on the ends of the pH scale that can result in severe corrosion and chemical attack of the pump body, gears, bushings, and elastomers. Pump construction will ultimately be driven by the specific liquid being handled and the construction that offers the greatest chemical resistance.

glue on a board


Adhesives are a group of substances, such as cement, glue, mucilage, and paste that are capable of holding materials together by surface attachment. Adhesives are made from many different basic materials, among them dextrin, latex, silicones, liquid rubber, resin, sodium silicate, and starch. 

Alcohols plant


Chemical compatibility ranges greatly based on the alcohol and the subsidiary branch chains attached to it, resulting in potential chemical attack of the pump body, gears, bushings, and elastomers. Pump construction will ultimately be driven by the specific alcohol being handled and the construction that offers the greatest chemical resistance.

laying asphalt

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.

laying asphalt

Asphalt Emulsions

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.

Black Liquor Soap

A natural intermediate byproduct of kraft pulping, black liquor soap is the rosin and fatty acid content that floats to the top as black liquor is left to settle. It is skimmed off and can be used as a raw material for tall oil production. Black liquor soap can be somewhat abrasive and range in viscosity from 22 to 5500 cP, depending on the temperature it is handled at.

Person caulking an object


Caulks can be silicone, acrylic, or latex based adhesives and sealants used in industrial and home construction. Typically high viscosity & shear sensitive.

sodium hydroxide tanks

Caustic (Sodium Hydroxide)

Sodium hydroxide is soluble in water, alcohol and glycerol. It is used in the manufacture of other chemicals, rayon and film, petroleum refining, pulp and paper, making of aluminum, refining vegetable oil, in detergents, soaps, textile processing, in reclaiming rubber and as an alkali in foods. The viscosity ranges from water-thin to 40 cP depending on concentration and temperature.

Chocolate bars


Cacao beans are roasted, ground up, and mixed with oils to get a semi-liquid which is the beginning point in the making of chocolate. Early stage chocolate is known as bitter chocolate. Add sugar and it is known as sweet chocolate. Add milk for milk chocolate. If the chocolate has been thinned down it is chocolate liquor. It can be diluted with fats like palm nut or coconut oils.

Olive oil bottling

Cooking Oils

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.

Jar of cosmetic cream

Creams (Medicinal, Cosmetic)

Creams are typically for personal use by consumers for cosmetic and surface medical treatments. Physical properties and chemistry can vary greatly depending on the cream base and added substituents. Some creams will be petroleum based like Petroleum Grease, while others may be emulsions suspended in water. They typically are shear-thinning mixtures.

Oil rig in a field

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.

detergent pod being placed into dish washer

Detergent Slurry

Detergent Slurry is a blend of liquid surfactant with powdered and granulated materials, such as builders and additives, that help to improve surfactant and cleaning performance.

Dye machine


Liquid based colorants are used in the chemical, petroleum, and industrial processes as a color indicator for identifying batch processes and what stage they are at in production. These dyes can be corrosive, such as "Red Dye" commonly used in Diesel Fuel production. When handling concentrated or pure dye, construction materials with high level corrosion resistance may be needed.

Fries frying in oil

Edible Oils

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.

organic ethanol in a bottle

Ethanol (Cold Ethanol Extraction)

Cold ethanol extraction is a common method for removing oils from plant material. Due to its polarity, ethanol is chilled to subzero temperatures to avoid extracting additional, less desirable water-soluble molecules. Pumps in this application may be used for circulating or transporting solvents at temperatures as low as -100F. 

shingles on roof

Filled Asphalt

Filled asphalts contain particulate used in the liquids’ end applications. Examples of this would be roofing materials and hot mix plants. Typically they are handled at elevated temperatures to reduce the viscosity of the asphalt mixture. The pump needs a source of heat like jacketing or electric heat to prevent the product from solidifying in the pump.

Hand sanitizer


This chemical is typically produced in the same process as soaps and surfactants. It is used in a wide variety of products ranging from food and beverage to personal care and disinfectants.

Injecting grease


Commonly referred to as lubricating, automotive, or bearing grease. Generally mixtures of a mineral oil with one or more metallic soaps; the most common are those of sodium, calcium, barium, aluminum, lead, lithium, potassium and zinc. The texture of grease may be smooth, buttery, ropy, fibrous, spongy or rubbery and have a variety of viscosities.

Heat transfer system in plant

Heat Transfer Liquids (Hot Oil)

Heat transfer liquids, heat transfer oil (HTO) or hot oil, are generally made from one of the following: mineral oil, diphenyls, modified terphenyls or polyalkalene glycols. Heat transfer liquids are used for transferring heat from a source to a point of use such as dies, presses, cooking vessels, processing equipment, etc. Most are handled at temperatures up to 600°F.

High fructose corn syrup in bottles on conveyer belt

High Fructose Corn Syrup (HFCS)

High Fructose Corn Syrup (HFCS) is usually followed by the percentage of fructose in the liquid, ranging from 42 to 55%. It is most commonly used in soft drinks, jams, and jellies as a sweetener. Temperature regulation is relevant because discoloration of the liquid could occur at elevated temperatures.

Glue gun ejecting hot melt

Hot Melt

Hot Melt adhesives are thermoplastic polymers that soften (become less viscous) when heated. Applied by a local system that melts the adhesive and adjusts pump speed to match the speed of the converting machine.

ink roller


Inks for flexible packaging are shear sensitive liquids that can have a variety of solvents, waxes, surfactants, and semi-solid resin particles, and pigment load concentrations that bring with them abrasive wear and chemical compatibility concerns.

Isocyanate in a lab


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.
