flowserve viscosity limit for centrifugal pump|hydrodynamics of centrifugal pump

The main characteristic curves of a centrifugal pump consisting of a variation of the head (manometric head, H m), power and discharge with respect to speed. For plotting curves of manometric head versus speed, discharge is kept constant.

Centrifugal pumps are widely used in various industries to move fluids from one place to another. However, the published performance curves of centrifugal pumps are typically based on water, which has a relatively low viscosity compared to many other fluids. When these pumps are used to move viscous fluids, the performance may not meet the expectations unless corrections are made.

Minimum continuous flow to prevent flashing in centrifugal pumps. 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

Centrifugal Pump Fluid Viscosity

Viscosity is a crucial factor that affects the performance of centrifugal pumps. Viscosity is a measure of a fluid's resistance to flow, and it determines how easily a fluid can be pumped through a system. In the context of centrifugal pumps, higher viscosity fluids require more energy to be pumped, which can impact the overall performance of the pump.

Centrifugal Pump Viscosity Chart

To account for the effects of viscosity on centrifugal pump performance, engineers often refer to viscosity correction charts. These charts provide guidelines on how to adjust the pump's performance curve based on the viscosity of the fluid being pumped. By using these charts, engineers can estimate the actual performance of the pump when handling fluids with different viscosities.

Flowserve Centrifugal Pump Manual

Flowserve is a leading manufacturer of centrifugal pumps, known for their high-quality products and comprehensive manuals. In the Flowserve centrifugal pump manual, detailed information is provided on how to handle different fluid viscosities and ensure optimal pump performance. The manual typically includes viscosity correction factors and guidelines on how to apply them to the pump's performance curve.

Hydrodynamics of Centrifugal Pump

The economical duty limit for centrifugal pumps is about 150.10-6 m 2 /s. Use of a centrifugal pump is possible up to about 500.10-6 m 2 /s. but a higher NPSH must be made …

Centrifugal pumps encompass a wide range of types, including single-stage, multi-stage, axial flow, radial flow, mixed flow, self-priming, and submersible pumps. Each type has its unique characteristics and applications, catering to .
