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
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...
Studies of ion pumps, such as ATP synthetase and Ca
-ATPase, have a
long history. The crystal structures of several kinds of ion pump have been
resolved, and provide static pictures of mechanisms of ion transport.
A displacement pump (also called positive-displacement, or just p-d) is a
pump which imparts energy to the pumpage (the material pumped) by
trapping a fixed volume at suction (inlet) conditions, compressing it to
discharge pressure, then pushing it into the discharge (outlet) line.
The performance characteristics of centrifugal pumps and fans (i.e., rotating fluid machines) are
described by the same basic laws and derived equations and, therefore, should be treated together
and not separately.
Operating / Parts Information
You must be familiar with the operation of this machine before you attempt to troubleshoot or make any repairs to it. Basic operating and maintenance procedures are described in the Operator’s Manual supplied with the machine. Keep a copy of it with the machine at all times. Use the separate Parts Book supplied with the machine to order replacement parts. If either of the documents becomes lost, please contact Wacker Corporation to order a replacement.
I will show you how to put your Bosch VE type injection pump head back on the pump body and how to install all the parts inside the pump. You most likely had leaking seals on your pump and pulled the head off to put a new seal on and everything fell inside and now you have a mess on your hands. This how-to shows the pump head and associated parts only. The injection quantity parts have been show in other threads. First, the only way to do this is take the pump off the car. Then take the...
The second volume of the book concerns the characterization approach of photonic crystals, photonic crystal lasers, photonic crystal waveguides and plasmonics including the introduction of innovative systems and materials. Photonic crystal materials promises to enable all-optical computer circuits and could also be used to make ultra low-power light sources.
