61Infusion pump — A type of infusion pump, manufactured by Fresenius. An infusion pump infuses fluids, medication or nutrients into a patient s circulatory system. It is generally used intravenously, although subcutaneous, arterial and epidural infusions are… …
62Fire pump — A fire pump is a part of a fire sprinkler system s water supply. The pump intake is either connected to the public underground water supply piping, or a static water source (e.g., tank, reservoir, lake). The pump provides water flow at a higher… …
63Sorption pump — The sorption pump is a vacuum pump that creates a vacuum by adsorbing molecules on a very porous material like molecular sieve which is cooled by a cryogen, typically liquid nitrogen. The ultimate pressure is about 10 2 mbar. With special… …
64Diffusion pump — Six inch oil diffusion pump. Diffusion pumps use a high speed jet of vapor to direct gas molecules in the pump throat down into the bottom of the pump and out the exhaust. Presented in 1915 by Wolfgang Gaede[1] and using mercury vapor, they were… …
65Diaphragm 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… …
66Negative-pressure wound therapy — Application of a vacuum pump using a foam dressing to a wound Negative pressure wound therapy (NPWT) is a therapeutic technique using a vacuum dressing to promote healing in acute or chronic wounds and enhance healing of first and second degree… …
67force pump — noun pump used to force a liquid up and expel it under pressure • Hypernyms: ↑pump * * * noun : a pump with a solid piston for drawing and forcing through valves a liquid (as water) to a considerable height above the pump or under a considerable… …
68Heat 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 …
69Rotary vane pump — 1. pump housing 2. rotor 3. vanes 4. springA rotary vane pump is a positive displacement pump that consists of vanes mounted to a rotor that rotates inside of a cavity. In some cases these vanes can be variable length and/or tensioned to maintain …
70Ion 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… …
