Unlike centrifugal pumps, positive displacement sliding vane pumps are dry-run capable, which means they do not need to be pre-primed, resulting in higher suction-lift ...

As addressed in an earlier article of this series, centrifugal pumps are the most common pumps in a process plant, and an operator’s understanding of how these systems work often will impact how much ...

Boiler feed pumps (BFPs) play a major role in the capacity and heat rate of a power-generating unit. As such, they merit routine performance testing to assess their condition and trend deficiencies to ...

Centrifugal pumps are the most common pumps in a process plant. Despite their pivotal role in operations, however, they are often the plant's least understood and most inefficiently operated equipment ...

Centrifugal pumps are one of the most popular types of pumps used both domestically and in industrial settings. There are various designs of centrifugal pumps (Figure 1), and they all work in a ...

Fire pump primers may not be glamorous, but priming systems are critical to pump drafting performance. Pulling a prime quickly is key to fast water delivery, a basic fireground necessity. Last month, ...

An important step when selecting a centrifugal pump and an electric motor for an application or when troubleshooting operation issues is to determine how much power the pump should be using. The ...

Fluid-handling or transfer devices are not basically concerned with the modulation or transfer of power, but only with the movement of fluid. Two major types of fluid-transfer pumps are ...
