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.


Various liquids designed to enhance or change the properties of the bulk liquid such as fuels, greases, and oils. These additive liquids include antioxidants, rust inhibitors, anti-wear agents and viscosity modifiers.


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. Adhesives are used in the manufacture of cardboard boxes, plywood, furniture, paper bags, pressure sensitive tapes and many industries including automotive, printing, manufacturing, etc.


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.


Ammonia (Refrigerant R-717) is a very thin liquid that is a gas at ambient temperature and pressure. It is typically kept at elevated pressure to keep it in liquid form. Ammonia is used as the refrigerant in cooling systems.

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.

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.

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.

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.

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. 

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.

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

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.

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.


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.


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. There are also the health & safety concerns of handling this product, making a sealless mag-drive option highly desirable.

Lecithin is a mixture of triglycerides, fatty acids, and carbohydrates that typically ranges in viscosity up to 5000 SSU, but may be more viscous depending on make-up and temperature. It is typically derived from soybean oil but may also be obtained from egg yolks, corn, or other vegetable seeds. It has a low solubility in water but is an excellent emulsifying agent, so it is used in margarine as well as chocolate and confectionary products as a non-sticking agent. 

Liquefied Gases

Liquefied gases are under high tank or system (inlet) pressure and lower temperatures to prevent them from vaporizing under atmospheric pressure and ambient temperature conditions. This includes Butane, Propane, Liquid Nitrogen, Methane, etc. The high system pressure keeps the gases in a liquid state and helps propel the liquid through the system under low differential pressure across the pump.

Liquid Fats

Recycled animal fats and vegetable oils are used in the production of animal feeds for many reasons including the acceleration of growth rates, improved taste, providing essential fatty acids and to act as a binder for producing feed pellets. Typical products include oils derived from corn, soybeans, peanuts as well as animal fats.

Alcohols having many hydroxyl radicals are called polyols. Many companies market polyols under their own trade names. Product viscosity varies greatly depending on the specific polyol, but can be as thick as 40,000 cP. Polyols are often blended with isocyanates, so pumps handing polyols are often requested to be built using isocyanate compatible lubricants.


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. If the polyurethane has already been blended with the isocyanate cure agent, refer to Isocyanate liquid.

Polyvinyl Acetate (PVAC)

Reclaimed Asphalt

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.

Refined Fuels

Refined fuels would include petroleum based fuel oils and some Jet Fuels. Their viscosity and temperature handled can vary greatly. Normally these are handled in bulk transfer operations.


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.

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, but rubber cement is normally considered to be quite viscous.


Shampoos are used for personal and pet care hygiene products. They typically are shear-thinning mixtures and lubricating.


Kettle soap, soap stock, soap skimmings, and liquid soap are a mixture of sodium salts of various fatty acids of natural oils and fats. Common soap is largely a mixture of the sodium salts of palmitic, stearic and oleic acids. Rosin soaps for laundry purposes are made by adding a soap made from rosin or rosin itself to an ordinary soap. Castile soaps are made from olive oil. Liquid soap is usually a potash soap dissolved in water.


The wide range of viscosity of various solvents plays a key role in determining the best pump for handling the application. Pump construction will ultimately be driven by the specific liquid being handled and the construction that offers the greatest chemical resistance and is the most viscosity appropriate.
