Pump A small, electrically powered pump A large, electrically driven pump for waterworks near the Hengsteysee, Germany A pump is a device that moves fluids (liquids or gases), or sometimes slurries, [1] by mechanical action, typically converted from electrical energy into hydraulic or pneumatic energy. Pump , a device that expends energy in order to raise, transport, or compress fluids. The earliest pumps were devices for raising water, such as the Persian and Roman waterwheels and the more sophisticated Archimedes screw (q.v.). The mining operations of the Middle Ages led to development of the Types of Pumps Pumps are classified into two types namely Dynamic pumps as well as Positive Displacement Pumps. Types of Pumps Dynamic Pumps Dynamic pumps are classified into different types but some of them are discussed below like Centrifugal, Vertical centrifugal, Horizontal centrifugal, Submersible, and Fire hydrant systems. PUMPS 1. Introduction The Pump is used to import energy to a fluid in a fluid system. It is run by using an external source such as electric motor. So that it can import pressure energy of kinetic energy or both energies to the fluid. In a pump the fluid flow takes place from the low pressure side to the high pressure side of the pump . By rotating the pump impeller by external source the fluid flow is accelerated to enable it to move from low pressure side to the high pressure side ...
