Self-priming pumps are liquid pumps designed to have the required liquid inside the cavity or pump body necessary to start the pumping process.These are self-priming centrifugal pumps with the benefits of a compact design, practical use, simple maintenance, high efficiency, and a powerful self-priming capability.Self-priming pumps excel in scenarios where automatic priming is essential, such as suction lifts and intermittent operations. Centrifugal pumps, despite priming challenges, remain versatile workhorses for various fluid transport applications.
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 …
The pump’s required suction pressure is known as net positive suction head required (NPSHR) and the water pressure at the inlet of the pump is known as net positive suction head available (NPSHA). So, in order for a centrifugal pump to run properly, net positive suction head available (NPSHA) must be greater than net positive suction head .
