Glycols are alcohols with unique properties, such as a high boiling point and good water solubility, that makes them attractive in many industries. Common examples include ethylene glycol, propylene glycol and polyethylene glycol. 

Positive displacement pumps are ideal for manufacturing glycerol and glycerin due to their ability to handle viscous fluids efficiently while maintaining a steady and precise flow rate. These pumps operate by trapping a fixed amount of fluid and then forcing (displacing) it into the discharge pipe, which makes them particularly suitable for the high viscosity and shear-sensitive nature of glycerol and glycerin.

Filled asphalts contain particulate and are used to manufacture asphalt roofing. The filler material improves durability and fire resistance of the shingle. Pumping filled asphalt requires special construction and operation to minimize abrasion, prevent leakage and extend pump life. 

Cold ethanol extraction is a common method for extracting oils from plant materials. Due to its polarity, ethanol is chilled to subzero temperatures to avoid extracting additional, less desirable water-soluble molecules.

In this application biomass is placed in vessel and cold ethanol solvent is pumped in. The desired oils are rapidly dissolved in this solvent. Unlike hydrocarbon solvents, ethanol has no risk of leaving toxic residual chemicals in the product, which is especially important if for human consumption.

Positive displacement gear pumps are ideal for transferring edible oils due to their precise flow control, efficiency, and gentle handling of viscous fluids. These pumps operate by trapping a fixed amount of fluid between the gear teeth and the pump casing, delivering consistent flow regardless of variations in pressure, making them perfect for the stable transfer of delicate edible oils. Their ability to handle varying viscosities without shearing or degrading the oil ensures the preservation of quality and nutritional value.

Positive displacement gear pumps are ideal for transferring dyes due to their ability to provide a consistent and precise flow rate, regardless of the system pressure. This advantage ensures that the dye is transferred smoothly and evenly, minimizing the risk of color inconsistencies in the final product. The design of gear pumps allows them to handle a wide range of viscosities, making them versatile when dealing with different dye formulations. Additionally, their robust construction ensures reliable operation with minimal maintenance, reducing downtime and operational costs.

Positive displacement gear pumps are ideal for transferring diesel #2 fuel oil due to their ability to handle viscous liquids with precision and efficiency. These pumps operate by trapping fluid between the gears and the casing, providing a consistent and predictable flow rate regardless of the changes in fluid pressure or viscosity. This makes them particularly well-suited for handling the thicker consistency of diesel #2 fuel oil, ensuring smooth and reliable transfer without cavitation or loss of prime.

Positive displacement gear pumps are ideal for transferring detergent slurry due to their ability to handle viscous fluids with precision and efficiency. These pumps operate by trapping a fixed amount of fluid and then forcing (displacing) it through the discharge pipe, maintaining a consistent flow rate regardless of the pressure conditions. This capability is crucial for detergent slurries, which often have a thick, viscous consistency.

Positive displacement pumps are ideal for transferring crude oils due to their ability to handle a wide range of viscosities and maintain a consistent flow rate regardless of pressure changes. These pumps move a fixed amount of fluid with each cycle, making them effective at pumping thick, viscous liquids like crude oil. Additionally, they can generate high pressures, making them suitable for transferring oil over long distances or through pipelines with varying elevations.

Positive displacement gear pumps are ideal for manufacturing medicinal creams due to their ability to handle high-viscosity fluids efficiently. They provide a consistent and precise flow rate, which is crucial for maintaining the quality and consistency of the creams. Additionally, these pumps offer gentle handling of shear-sensitive materials, minimizing the risk of altering the product's properties during the pumping process.
