### Section TECH-A Centrifugal Pump Fundamentals

A centrifugal pump imparts velocity to a liquid. This velocity energy is then transformed largely into pressure energy as the liquid leaves the pump. Therefore, the head developed is approximately equal to the velocity energy at the periphery of the impeller This relationship is expressed by the following well-known formula: H = v2 2g

### A BRIEF INTRODUCTION TO CENTRIFUGAL PUMPS

head (pressure) developed by a centrifugal pump depends upon the rotational speed and, more precisely, the peripheral velocity of its impeller (pail). Peripheral Velocity Head Gravity is one of the more important forces that a centrifugal pump must overcome. You will find that the relationship between final

### Impeller Diameter Relationships in Centrifugal Pumps - API 610

IMPELLER DIA. Rated Max. Min. You will probably never use equation (1) in pump calculations, but the relationship of head to pump speed and impeller diameter is very important. The pump head increases with the square of the pump speed and impeller diameter.

### Selecting a Centrifugal Pump by System Analysis

Selecting and Sizing a Centrifugal Pump The actual methods of arriving at the final style and size of a centrifugal pump vary widely. If the entire system is well defined with one set of constant operating conditions, then sizing a pump is a straightforward, simple process involving fluid dynamics fundamentals. The design flow rate in

### Characteristics of Centrifugal Pumps Pumps Systems

Sep 01, 2012 Positive displacement pumps have a constant torque characteristic, whereas centrifugal pumps demonstrate variable torque characteristics. This article will discuss only centrifugal pumps. A centrifugal pump converts driver energy to kinetic energy in a liquid by accelerating the fluid to the outer rim of an impeller.

### Centrifugal Pumps - Engineering ToolBox

The head is constant, even if the density (and therefore pressure) changes. The head of a pump can be expressed in metric units as: h = (p2 - p1) / (ρ g) + v22 / (2 g) (1) where h = total head developed (m) p2 = pressure at outlet (N/m2) p1 = pressure at inlet (N/m2) ρ = density (kg/m3) g = acceleration of gravity (9.81) m/s2
