A pump is a device used to move liquids or slurries. A pump moves liquids from lower pressure to higher pressure, and overcomes this difference in pressure by adding energy to the system (such as a water system). A gas pump is generally called a compressor, except in very low pressure-rise applications, such as in heating, ventilating, and air-conditioning, where the operative equipment consists of fans or blowers. A Pump is a mechanical device used to move fluids and slurries. ...

Pumps work by using mechanical forces to push the material, either by physically lifting, or by the force of compression.


The earliest type of pump was the Archimedes screw, described by Archimedes in the 3rd century BC, but used earlier by Sennacherib, King of Assyria, in the 7th century BC.[1] In the 13th century AD, al-Jazari described and illustrated different types of pumps, including reciprocating pumps, double acting pumps with suction pipes, water pumps, and pistons.[2][3] Archimedess screw (also the Archimedean screw) is one of several inventions and discoveries reputed to have been made by Archimedes. ...

A two-lobe pump (multiple rotor, positive displacement type)

Pumps fall into two major groups: rotodynamic pumps and positive displacement pumps. Their names describe the method for moving a fluid. Rotodynamic pumps are based on bladed impellers which rotate within the fluid to impart a tangential acceleration to the fluid and a consequent increase in the energy of the fluid. The purpose of the pump is to convert this energy into pressure energy of the fluid to be used in the associated piping system. Image File history File links Rotary_piston_pump. ...

A positive displacement pump causes a liquid to move by trapping a fixed amount of fluid and then forcing (displacing) that trapped volume into the discharge pipe. Positive displacement pumps can be further classified as either rotary-type (for example the rotary vane) or lobe pumps similar to oil pumps used in car engines. Another common type is the Wendelkolben pump or the helical twisted Roots pump. The low pulsation rate and gentle performance of this Roots-type positive displacement pump is achieved due to a combination of its two 90° helical twisted rotors, and a triangular shaped sealing line configuration, both at the point of suction and at the point of discharge. This design produces a continuous and non-vorticuless flow with equal volume. High capacity industrial "air compressors" have been designed to employ this principle as well as most "supercharges" used on internal combustion engines.

Reciprocating-type pumps use a piston and cylinder arrangment with suction and discharge valves integrated into the pump. Pump arrangements are from "simplex" one cylinder to in some cases four (quad) or more but usually are "duplex" two or "triplex" 3 cylinder. Furthermore they are either "single acting" independent suction and discharge strokes or "double acting" suction and discharge in both directions. The pumps can be powered by air, steam or through a belt drive from an engine or motor. This type of pump was used extensively in the early days of steam propulsion (19th century) as boiler feed water pumps. Though still used today reciprocating pumps are typically used for pumping highly viscous fluids including concrete and heavy oils. Another modern application of positive displacment pumps are diaphragm pumps commonly called "Sand Piper Pumps" and are used extensivley for dewatering and generally use compressed air as a motive source of energy.
In mechanics, a diaphragm is a sheet of a semi-flexible material anchored at its periphery and most often round in shape. ...


Centrifugal Pumps

Centrifugal Pumps are rotodynamic pumps which convert Mechanical energy into Hydraulic energy by centripetal force on the liquid. Typically, a rotating impeller increases the velocity of the fluid. The casing, or volute, of the pump then acts to convert this increased velocity into an increase in pressure. So if the mechanical energy is converted into a pressure head by centripetal force, the pump is classified as centrifugal. Such pumps are found in virtually every industry, and in domestic service in developed countries for washing machines, dishwashers, swimming pools, and water supply. The centripetal force is the external force required to make a body follow a circular path at constant speed. ...


A wide range of designs are available, with constant and variable speed drives. Horizontal shafts are the most common. Single-stage pumps are usual in the smaller ratings. Pumps with up to 11 stages are in service. A demanding duty is boiler feed, and today's designs are typically 3 - 4 stage, with speeds of up to 6000 revolutions per minute.


After motors, centrifugal pumps are arguably the most common machine, and they are a significant user of energy. Given design margins, it is not unusual for a pump to be found to be over-sized, having been selected poorly for its intended duty. Running a constant speed pump throttled causes energy waste. A condition monitoring test can detect this condition and help size a smaller impeller, either new, or by machining the initial one, to achieve great energy reduction.


Pumps also wear internally, at a rate varying with the liquid pumped, materials of construction and operating regime. Again, condition monitoring can be applied to detect and quantify the extent and rate of wear and also help decide when overhaul is justified on an energy-saving basis.

Pumps are used throughout society for a variety of purposes. Early applications includes the use of the windmill or watermill to pump water.

Sewage is the mainly liquid waste containing some solids produced by humans which typically consists of washing water, faeces, urine, laundry waste and other material which goes down drains and toilets from households and industry. ...


Because of the wide variety of applications, pumps have a plethora of shapes and sizes: from very large to very small, from handling gas to handling liquid, from high pressure to low pressure, and from high volume to low volume.


Pumps as public water supplies

One sort of pump once common was a hand-powered water pump over a water well or water main where people could work it to extract water, before most houses had individual water supplies.

A municipal water system is a large system of reservoirs and large-scale piping which supplies fresh water, suitable for human consumption, to houses and other residences. ...


From this came the expression "parish pump" for "the sort of matter chattered about by people when they meet when they go to get water", "matter of only local interest".
