fluid pump
31Progressive cavity pump — A progressive cavity pump is also known as a progressing cavity pump, eccentric screw pump or even just cavity pump and, as is common in engineering generally, these pumps can often be referred to by using a genericized trademark. Hence names can …
32Heat pump — A heat pump is a machine or device that moves heat from one location (the source ) to another location (the sink or heat sink ), using work. Most heat pump technology moves heat from a low temperature heat source to a higher temperature heat sink …
33Gear pump — [ Gerotor pump] A Gear pump uses the meshing of gears to pump fluid by displacement. They are one of the most common types of pumps for hydraulic fluid power applications. Gear pumps however are also widely used in chemical installations to pump… …
34Peristaltic pump — A peristaltic pump is a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained within a flexible tube fitted inside a circular pump casing (though linear peristaltic pumps have been made). A rotor with a… …
35Diaphragm pump — schematic. A diaphragm pump is a positive displacement pump that uses a combination of the reciprocating action of a rubber, thermoplastic or teflon diaphragm and suitable non return check valves to pump a fluid. Sometimes this type of pump is… …
36Supercritical fluid extraction — (SFE) is the process of separating one component (the extractant) from another (the matrix) using supercritical fluids as the extracting solvent. Extraction is usually from a solid matrix, but can also be from liquids. SFE can be used as a sample …
37Ion pump (physics) — An ion pump works by creating an electric field across a fluid containing ions. An ion is an electrically charged atom or molecule. If the fluid does not naturally contain ions, then it must be ionized before an ion pump will work. A fluid is… …
38Eductor-jet pump — An eductor jet pump or aspirator can be used for draining areas which may contain combustible fluids (which could ignite if exposed to the workings of a standard electric or internal combustion powered pump) or high levels of debris which could… …
39Vacuum pump — A vacuum pump is a device that removes gas molecules from a sealed volume in order to leave behind a partial vacuum. The vacuum pump was invented in 1650 by Otto von Guericke. Types Pumps can be broadly categorized according to three… …
40Geothermal heat pump — A geothermal heat pump system is a heating and/or an air conditioning system that uses the Earth s ability to store heat in the ground and water thermal masses. These systems operate based on the stability of underground temperatures: the ground… …
