A pump is a device that moves fluids, or sometimes slurries, by mechanical action. Pumps can be classified into three major groups according to the method they use to move the fluid: direct lift, displacement, and gravity pumps. Electric motors are often used to drive centrifugal pumps for high-pressure systems that require large volumes of water or other liquid at a low flow rate (such as irrigation). Many reciprocating or syringe-type devices use suction via the Venturi effect in order to produce a pressure difference from one side of their chamber to the other. The pressure impeller has a series of blades that takes in dirty fluid from the inlet port and throws it out through the discharge port at high speeds which creates a vacuum on the other side. The vacuum draws in more dirty fluid through an inlet port resulting in circulation through one complete revolution of the impeller.

A pump is a device that moves fluids, or sometimes slurries, by mechanical action. Pumps can be classified into three major groups according to the method they use to move the fluid: direct lift, displacement and gravity. Direct lift pumps are typically used for liquids, such as water and other fluids with similar viscosity characteristics of liquid (low flow rate, high pressure head). Displacement pumps are used for high flow rates of viscous liquids, slurries and gases (typically low pressure head). Gravity pumps are used for liquids with low viscosity characteristics (high flow rate).

 

While many pumps fit into more than one classification, the main types are direct lift, displacement and gravity pumps. Direct-lift pumps deliver fluids against gravity. Displacement pumps use pressure to push fluids like hydraulic jacks and steam engines. The most common form of pump is the reciprocating engine which is a combination of the two other forms: displacement from the cylinders; however there are some sub-classifications of this group such as a rotary lobe pump or gear pump where rotation is involved in pushing oil up in an axial direction for example in a gasoline engine. Another type of pump used for high pressure applications is called a centrifugal pump. Centrifugal pumps rotate at high speeds inside a closed chamber using line pressure produced by the motor as motive fluid until it exits through an opening at one end of the chamber called an impeller that causes air pressure to push on fluids known as dynamic head at higher speed than they entered through another opening called a discharge nozzle that pushes liquids outwards against gravity away from the impeller towards tanks or other containers.

 

A pump is a mechanical device that moves fluids or slurries by mechanical action. The pump may be either below or above the liquid level. In the past, there has been considerable debate as to whether a particular device should be called a pump or an engine; many devices have been described as both. In general however. Pumps are not classified according to their external appearance but instead by how they work (International Organization for Standardization [ISO] 121952). All pumps work in a very similar way: modern pumps operate on [pressure] difference, whereas older ones to push liquid uphill. The energy for moving fluid must be obtained from somewhere like a battery, motor or turbine

 

A pump is a mechanical device that moves liquids, gases and slurries by generating a pressure difference across an aperture or hole. It consists of a suction side, which draws liquid in to the pump, and a discharge side where the liquid is ejected. A pressure vessel containing the fluid to be moved is usually attached to the discharge side.
