Centrifugal pump - Wikipedia

Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine or electric motor. They are a sub-class of dynamic axisymmetric work-absorbing turbomachinery. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller ...

What is a Centrifugal Pump | Intro to Pumps

A centrifugal pump is a machine that uses rotation to impart velocity to a liquid, it then converts that velocity into flow. Centrifugal pumps are made up of two primary components: an impeller and a casing. The rotating impeller generates velocity and the casing converts velocity into flow.

Centrifugal Pump Hydraulics by the Numbers: Radial Thrust ...

I was asked by a pump manufacturer to determine the actual radial shaft deflection, at the mechanical seal, for a line of vertical, in-line centrifugal pumps, similar to that in Figure 3. The pump shaft was rigidly coupled to the motor shaft so that, when the pump was equipped with a mechanical seal, the motor bearings absorbed both axial and radial thrusts from the pump.

Lubricating And Troubleshooting Centrifugal Pumps ...

Some pump manufacturers recommend antiwear (AW) additives, but most use R&O oils. Viscosity is the most important criteria in the selection of the proper pump lubricant. Table II lists guidelines on the proper viscosity selection for rolling-element bearings. The most common viscosity used for centrifugal pump rolling-element bearings is ISO VG 68.
