Understanding Centrifugal Pump Curves - MGNewell

Understanding Centrifugal Pump Curves When selecting a centrifugal pump, one should match the performance of the pump to that needed by the system. To do that, an engineer would refer to a pumps composite curve. A typical composite curve includes the pump performance curves, horsepower curves and NPSH required.

Pump Training - EDGE

Pump Training Published by permission of Sykes Innovative Solutions, Australia Pump Terms Head Centrifugal pump curves show 'pressure' as head, which is the equivalent height of water with S.G. = 1. This makes allowance for specific gravity variations in the pressure to head conversion to cater for higher power requirements.

Assembly & Maintenance Exercise: In-Line Centrifugal Pump ...

In-line centrifugal pumps are a sub-category of centrifugal pumps. Centrifugal pumps are one of the most common types of pumps. In-line pumps are installed in the straight runs of pipelines. The difference between an in-line pump and a standard pump is that the intake and delivery connections of an in-line pump are on one axis.

Experiment (9): Centrifugal pump Introduction

centrifugal pump is, by contrast, a rotodynamic machine. Rotodynamic (or simply dynamic) pumps impart momentum to a fluid, which then causes the fluid to move into the delivery chamber or outlet. Turbines and centrifugal pumps all fall into this category. Centrifugal pumps are widely used in industrial and domestic situations.

Benefits of Pumping In Series with Centrifugal Pumps

When centrifugal pumps are connected in a line, head increases from one pump to the next, increasing fluid pressure as well. A multi-stage pump, like a vertical turbine, does essentially the same thing. When two of the same pumps are in series, the combined performance curve will have double the head of a single pump for the given flow rate.

These energy changes take place courtesy of two main centrifugal pump components – the volute or diffuser and the impeller. The diffuser is the stationary part which converts kinetic into pressure energy while the impeller is the component that rotates and transforms driver force into kinetic energy.

How To Operate Centrifugal Pumps In Series Or Parallel

Putting your centrifugal pumps in series, or connected along a single line, will let you add the head from each together and meet your high head, low flow system requirements. This is because the fluid pressure increases as the continuous flow passes through each pump, much like how a multi-stage pump …

Pump Basics Training Video - Convergence Training

A gear pump uses the pockets created by a pair of turning gears to transfer and pump fluid. At the inlet side of the pump, fluid flows into the area where turning gears separate from each other. As the gears rotate and meet the casing of the pump, fluid is trapped in the space between the teeth and the case.
