Centrifugal pumps serve as workhorses in the chemical industry. However, highly variable flow rates and low net positive suction head (NPSH) operation can be tough on such pumps.

While standard centrifugal pumps are typically used for mixing, blending and transporting product from points A to B, moving product with minimal shearing requires a positive-displacement (PD) pump.

The most common electric bilge pumps found today are the Rule-type centrifugal pumps. While these pumps are very common, they are not the best bilge pumps in my opinion.

As the pump impeller rotates, the fluid flows outward from the central axis into a chamber where it is discharged. As the fluid leaves the the axis of the impeller, a low pressure area is created and

Centrifugal pumps are connected in series if the discharge of one pump is connected to the suction side of a second pump. Two similar pumps, in series, operate in the same manner as a two-stage centri

The original industrial pump which was installed failed to operate successfully requiring them to be replaced. Before replacements could be sourced, a detailed analysis of the pump system which had b

A centrifugal pump is known as a constant head machine and the head is measurable in either meters or feet. The liquid, usually water, will enter the pumping portion of the unit and then go through th

Key topics which the book homes in on are: the various types of centrifugal pumps; relevant pump terminology; pump characteristics and pump curves; pump calculations; auxiliary equipment associated wi
