Selecting the Right Pumps for High Viscosity Fluids in Industrial Applications
For pumping high viscosity liquids in industrial production, various types of pumps are employed to ensure efficient handling and minimal maintenance. Here are some pumps that excel in dealing with thick fluids like oils, resins, coatings, and chemicals:
1. Specialized Volume Pumps: Designed specifically for high-viscosity fluids, these pumps, often called positive displacement pumps, adjust their chamber volume to move liquid. They feature robust construction and materials, making them ideal for applications in the petrochemical, coatings, and lubricants sectors. In coating production, they help maintain precise flow control and pressure.
2. Gear Pumps: When standard centrifugal pumps falter, gear pumps are a popular choice. They use the meshing action of gears to move viscous liquids, such as fats and certain chemicals. Gear pumps are known for their simplicity, reliability, and ability to handle solids in the fluid. However, caution is needed to prevent overheating at high viscosities.
3. Air-Driven Diaphragm Pumps: These pumps, powered by compressed air, offer exceptional adaptability and can manage corrosive, solid-laden liquids. With their self-contained design, they provide good hygiene, ease of cleaning, and are preferred in food, pharmaceutical, and other hygienic industries.
4. Screw Pumps: Known for their prowess in handling thick fluids, screw pumps have two interlocking screws rotating within the casing. Ideal for high-viscosity slurries or suspensions, they provide stable and continuous output by adjusting motor speed. They are commonly found in wastewater treatment and petrochemical processes due to their strong suction and smooth operation.
In summary, various specialized pumps are employed in industrial settings to effectively transport high viscosity liquids, each offering unique features and advantages tailored to specific applications and requirements.
