| Positive Net Suction NPSHA Analysis Formula |
| With the design of pump systems attention should be given to the pressure and temperature of the water as it enters the pump, especially in condenser towers, steam condensate returns, and steam boiler feeds. The pressure in excess of that required to prevent vapor pockets from forming is the Net Positive Suction Head Required (NPSHR). NPSHR is a characteristic of a given pump and varies with pump speed and flow. It is determined by the manufacturer and is included on the pump performance curve. |

| The Centrifugal Pump |
| ’The Centrifugal Pump’ is primarily meant as an inter-nal book and is aimed at technicians who work with development and construction of pump components. Furthermore, the book aims at our future colleagues, students at universities and engineering colleges, who can use the book as a reference and source of inspiration in their studies. Our intention has been to write an introductory book that gives an overview of the hydraulic components in the pump and at the same time enables technicians to see how changes in construction and operation influence the pump performance. |

| Hydraulic Ram for Pumping Water |
| Operation and Design Hydraulic Ram Pump for Pumping Water. The automatic hydraulic ram is a pumping device that has been widely used for nearly a century in rural areas, for lifting water to heights of over 100 meters |
|
| Fire Pumps |
| Fire pumps are used to move water through a fire sprinkler system or to manual hose bibs in commercial or industrial applications. The pump's intake is most often connected to an external water supply, though sometimes it can be connected to a local water source such as a tank or well. |
|
| Submersible Pumps |
| Submersible pumps are designed to function with both pump and motor submerged in the fluid to be pumped. The motor of this centrifugal pump is sealed in a way that prevents liquid from seeping in, protecting against short-outs. |
|
| Self Priming Pumps |
| A self-priming pump is a centrifugal pump that removes the need for external priming devices. |
|
| End Suction Pumps |
| End suction pumps are one of the most common types of centrifugal pumps. Learn more about these pumps and what applications they're used. |
|
| Vertical Turbine Pumps |
| Vertical turbine pumps are centrifugal pumps specially designed to move water from an underground well or reservoir. They're also known a deep well turbine pumps or a line shaft turbine pumps. |

| Scroll Compressor Review |
| A scroll compressor (also called spiral compressor, scroll pump and scroll vacuum pump) is a free standing involute spiral which is bounded on one side by a solid flat plane, or base.
