Back to Basics: Pump Types - End Suction Vs. Double Suction ...

An end suction water pump would probably have the lowest initial cost for most applications, with reasonable efficiency. However ... Double suction, between bearing, split case pumps (see figure 3) are the second most popular centrifugal pump configuration, second only to the more common end suction, radial split design.

Numerical Prediction of NPSHR Characteristics of Double Suction ...

Abstract - The pressure at inlet of pump is mostly below atmosphere pressure and may come below the vapour pressure of water depending on installation and operating condition. This situation may lead to cavitation in pump and it is one of the leading causes for reduced reliability on performance of centrifugal pumps.

A steel plant has received offers for cooling water pump from four manufacturers. The pump is required to be run over a wide range of flows. On scrutiny, all four pumps are found to operate at or very close to B.E.P and their efficiencies are identical. The installation has flooded suction (NPSHa = 10 m).
