Pumps, Valves & Accessories info:
A pump uses pressure differentials to transport various liquids and gases from one place to another. There are two major types of pump: positive displacement pumps, which force a specific volume of fluid through a pressurized discharge channel, and rotodynamic pumps, which use rotating blades to accelerate fluid and convert its kinetic energy into pressure. Positive displacement pumps can provide continuous material flow even at different pressures, and they are used in chemical processing, beverage and liquid production, and the pharmaceutical industry. Rotodynamic, or centrifugal, pumps are generally more powerful and can be found in a wide variety of applications, including irrigation networks and sewage systems.
A valve is a mechanism for regulating the flow of liquids and gases, and it is often found in pump systems. Valves manage material flow by opening, narrowing, or closing a pipe passage. They come in a wide range of physical dimensions and properties, such as gate, plug, butterfly, check, and ball valves. They are commonly used in plumbing, sewage systems, the oil and gas industries, and numerous residential applications.

What Is Water Hammer?
Outlining the various causes for the occurrence of water hammer or hydraulic shock in a pipe, this paper provides information on how to prevent or reduce water hammer. Water hammer is the momentary increase in pressure inside a pipe caused by a sudden change of direction or velocity of the liquid in the pipe. With the help of examples, the paper...
