Centrifugal pump

OverviewHistoryHow it worksVertical centrifugal pumpsFroth pumpsMultistage centrifugal pumpsCentrifugal 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, flowing radially outward into a diffuser or volute chamber, from which it exits. Common uses include water

Centrifugal Pumps Characteristics | Marine Notes

Centrifugal Pumps Characteristics. Centrifugal Pumps. Pumps. Pump is a device, which adds to the energy of a liquid or gas causing an increase in its pressure and perhaps a movement of the fluid. A Simple Pumping System. A simple pumping system consists of a suction branch, a pump, and a discharge branch. See the figure above.

Centrifugal Pump Characteristic Curve

Centrifugal Pump Characteristic Curve. For a given centrifugal pump operating at a constant speed, the flow rate through the pump is dependent upon the differential pressure or head developed by the pump. The lower the pump head, the higher the flow rate. A vendor manual for a specific pump usually contains a curve of pump flow rate versus pump ...

Pressure, friction and flow are three important characteristics of a pump system. Pressure is the driving force responsible for the movement of the fluid.

How To Read A Centrifugal Pump Curve

Jun 26, 2014 · In this post, we'll break down the anatomy of a centrifugal pump curve. A centrifugal pump imparts energy on a liquid, and based on the system it is installed on, has flow and head characteristics. The amount of pressure the pump is required to overcome dictates where the performance point will be on the curve and how much flow is produced.

The centrifugal pump was developed in Europe in the late 1600’s and was seen in the United States in the early 1800’s. Its wide spread use, however, has occurred only in the last seventy-five years. Prior to that time, the vast majority of pumping applications involved positive displacement pumps. The increased popularity of centrifugal pumps

What is Centrifugal Pump

Performance Characteristics of Centrifugal Pumps. Although the theory of centrifugal pumps gives many qualitative results, the most important indicator of a pump’s performance lies in extensive hydraulic testing. In industry, characteristics of all pumps are usually read from its Q-H curve or performance curve (flow rate – height).
