  • A centrifugal pump is a rotating machine in which flow and pressure are generated dynamically. The inlet is not walled off from the outlet as is the case with positive dis- placement pumps,whether they are reciprocating or rotary in configuration. Rather, a cen- trifugal pump delivers useful energy to the fluid or “pumpage” largely through velocity changes that occur as this fluid flows through the impeller and the associated fixed pas- sageways of the pump; that is, it is a “rotodynamic” pump.

  • In the Department of Structural and Fluid Mechanics we are happy to present the first English edition of the book: ’The Centrifugal Pump’. We have written the book because we want to share our knowledge of pump hydraulics, pump design and the basic pump terms which we use in our daily work. ’The Centrifugal Pump’ is primarily meant as an internal book and is aimed at technicians who work with development and construction of pump components.

  • When Val and I decided to collaborate and write the first edition, our goal was to produce an easy-to-read, easy-to-understand, practical text- book stressing hydraulic design, that could be of hands-on use to the pump designer, student, and rotating equipment engineer. Although feed- back from readers indicates that we achieved our desired goal, we did recognize that we had omitted several important topics.

  • Low specific speed centrifugal pumps have low flow rates and high heads. They are widely applied in the petroleum, chemical, aerospace, pharmaceuticals, metallurgy, and light industries, among others. With the development of space technology and petrol chemical industry, the highly stable cavitation performance of centrifugal pumps has been put forward. Poor cavitation performance is one of the key problems in low specific speed centrifugal pumps.

  • A Liqui-Mover pump is a positive displacement pressure powered pump with a minimum of moving parts. The pumping action is accomplished using a positive pressure to push the liquid from the pump tank into the return line. The Liqui-Mover pump can handle high temperature and high pressure condensate without difficulty. Liqui-Mover pumps are available in nine sizes. They are available in many configurations, from individual components that are field assembled to complete packaged systems ready for connection to field piping.

  • Larry Bachus and Angel Custodio met each other in the early 1990s in Puerto Rico. Larry was working on a pump and seal conversion in a pharmaceutical chemical plant and Angel was installing a computerized preventive maintenance system in the same plant. They had passed each other in the administrative offices at the plant and one day the maintenance engineer introduced them and suggested they work together. They became fast friends and have worked together on numerous projects over the years since, including this book....

  • The centrifugal pumps with the actual configuration constitute a machine widely used for more than 150 years. The pumps are analyzed and examined in detail, a lot of experience from the design, construction and application of centrifugal pumps is accumulated worldwide but still there is an endless number of topics that need supplementary examination, mainly of topics arising from the interaction between the pump and the pumping installation.

  • What is a heat pump? A heat pump is a mechanical device used for heating and cooling which operates on the principle that heat can be pumped from a cooler temperature to a warmer temperature (cold to hot). Heat pumps can draw heat from a number of sources, eg, air, water, or earth, and are most often either air-source or water-source. Although heat pumps have been around for more than a 100 years, the technology has dramatically increased. Not only do heat pumps still operate the common refrigerator, but today, heat pump technology allows us to heat and cool residential...
