A cryogenic centrifugal pump is a type of centrifugal pump which is designed to be used in extreme temperatures, specifically those below the boiling point of water. It is a .
Centrifugal pumps are widely used in various industries for transferring fluids, including liquids with different viscosities. The viscosity of the fluid being pumped plays a crucial role in the performance and efficiency of centrifugal pumps. Understanding the relationship between centrifugal pump viscosity and the characteristics of the fluid being handled is essential for proper pump selection and operation.
Centrifugal pumps and maximum shut-off head. Viscosity at 20°C/68°F and 50°C/122°F for more than 120 crudes is shown as function of specific gravity@15°C/60°F. An introduction to density, specific weight and specific
Centrifugal Pump Fluid Viscosity
Viscosity is a measure of a fluid's resistance to flow. In the context of centrifugal pumps, fluid viscosity refers to how easily a fluid can be pumped through the pump system. The viscosity of the fluid can have a significant impact on the pump's efficiency, power consumption, and overall performance.
Centrifugal Pump Viscosity Chart
A centrifugal pump viscosity chart provides valuable information on the viscosity of various fluids at different temperatures. The chart typically shows the viscosity of fluids at 20°C/68°F and 50°C/122°F as a function of specific gravity at 15°C/60°F. This information is crucial for pump operators to determine the appropriate pump size and configuration for handling different fluids.
Centrifugal Pump Viscosity Limit
Every centrifugal pump has a viscosity limit beyond which its performance may be compromised. Operating a pump beyond its viscosity limit can lead to issues such as reduced flow rates, increased power consumption, and potential damage to the pump components. It is essential to consult the pump manufacturer's guidelines to determine the viscosity limits for a specific pump model.
Viscosity of Pumps
The viscosity of the fluid being pumped can vary significantly depending on the type of fluid and its temperature. Pump manufacturers provide viscosity data for a wide range of fluids to help users select the appropriate pump for their application. Understanding the viscosity characteristics of the fluid is crucial for ensuring the pump operates efficiently and reliably.
Does Viscous Fluid Affect Centrifugal Pump?
Viscous fluids can pose challenges for centrifugal pumps due to their higher resistance to flow. When pumping viscous fluids, the pump may experience lower flow rates, increased power consumption, and reduced efficiency. It is essential to consider the viscosity of the fluid when selecting a centrifugal pump to ensure optimal performance and longevity of the pump system.
Rotary Pump Viscosity
Rotary pumps, such as gear pumps and screw pumps, are better suited for handling highly viscous fluids compared to centrifugal pumps. These pumps are designed to efficiently transfer thick and sticky fluids with higher viscosities. When dealing with extremely viscous fluids, rotary pumps may be a more suitable choice to ensure smooth and reliable fluid transfer.
Pump Shaft Viscosity
The viscosity of the fluid being pumped can also affect the lubrication of the pump shaft and bearings. High-viscosity fluids may require special considerations for lubrication to prevent excessive wear and friction on the pump components. Proper maintenance and monitoring of pump shaft viscosity are essential to prolong the pump's lifespan and prevent costly repairs.

Note: it is not advisable to keep a pump running at zero flow for long periods of time. The total head at zero flow is the maximum head also called the shut-off head, the total head decreases as the flow increases. The plot of total head vs. flow for a centrifugal pump is very typical and it looks like this: Figure 6 Typical curve of total head .
