Replace Packing or Mechanical Seals with O-Pro®
Each O-Pro® Seal design option replaces packing or a mechanical seal by occupying the internal bracket cavity with a machined seal gland. Utilizing O-rings to seal externally on the bracket and internally on the shaft, a combination of O-rings and lubricating grease provide a robust seal. This prevents process fluids from leaking out of the pump.
O-Pro® Barrier Seal
The O-Pro® Barrier seal also replaces the bracket bushing - which allows the entire bracket to be sealed off from process liquid.
O-Pro® Cartridge Seal
The O-Pro® Cartridge seal allows for an easy retrofit while addressing any need for stainless steel seal construction.
O-Pro® Guard Seal
The stainless steel construction utilizes a sleeve that is secured to the shaft to address any shaft wear concerns to ensure superior performance.

Liquids
Adhesives
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.
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.
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.
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.
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.
Greases
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.
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.
Wax
Waxes can be natural secretions of plants or animals, such as beeswax, or by-products of petroleum refining. Wax is commonly used in the paper and boxboard industries to make products such as cartons and paper packaging moisture resistant. Wax can also help prevent food products from sticking to paper packaging.
Lecithin
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.
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.
Molasses
Molasses is defined as the syrupy mother liquor left after sucrose has been removed from the cane juice by concentration. If only one crop of crystals had been removed, it is called First Molasses. If the second crop has been removed, the product is termed Second Molasses, and so on. When no more cane sugar can be extracted it is called Final Molasses or Black Strap Molasses.
Polyurethanes
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.
Polyvinyl Acetate (PVAC)
Poly Vinyl Acetate, or PVAC, is a colorless, odorless, tasteless, non-toxic, transparent, thermoplastic solid. It is used in latex water paints, in hot melt and other types of adhesives, for coating and finishing fabrics, as a component of lacquers, inks and in caulking compounds and chewing gum. PVAC is insoluble in water, oils and fats, but soluble in alcohols, esters, benzene and ketones.
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.
Resins
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.
Starch
Starch is derived from corn, arrowroot or potatoes. It is shear sensitive (thickens) and viscosity varies from a few centipoise to over 20,000 cP depending on the type of starch, concentration in the liquid, and temperature.
Tall Oil Soap
A natural intermediate byproduct of kraft pulping, tall oil soap is the rosin and fatty acid content of black liquor that is skimmed off and used as a raw material for tall oil production. Tall oil soap can be somewhat abrasive and range in viscosity from 22 to 5500 cP, depending on the temperature it is handled at.
