rotor pump
11Progressive 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 …
12Turbomolecular pump — A turbomolecular pump is a type of vacuum pump, superficially similar to a turbopump, used to obtain and maintain high vacuum. These pumps work on the principle that gas molecules can be given momentum in a desired direction by repeated collision …
13Rotary 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 …
14Peristaltic 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… …
15Hand pump — This article is about water and air pumps. For the beer dispensing device, see Beer engine. A rural handpump in Belgium. Hand pumps are manually operated pumps; they use human power and mechanical advantage to move fluids or air from one place to …
16vane pump — A type of rotary pump with either a slotted rotor and sliding vanes or a rotor with hinged vanes; typically used for air pumps in secondary air injection systems, as a compressor in air conditioning systems, and in some transmission systems. See… …
17Centrifugal pump — Warman centrifugal pump in a coal preparation plant application A centrifugal pump is a rotodynamic pump that uses a rotating impeller to create flow by the addition of energy to a fluid. Centrifugal pumps are commonly used to move liquids… …
18Axial piston pump — An axial piston pump is a positive displacement pump that has a number of pistons in a circular array within a cylinder block. It can be used as a stand alone pump, a hydraulic motor or an automotive air conditioning compressor. Contents 1… …
19sliding-vane pump — A positive displacement pump in which an eccentric rotor revolves in an eccentric or circular case. Also see external vane pump. The pumping element consists of multiple blades which slide in slots in the rotor and divide the crescent shaped… …
20internal gear pump — A gear pump which has one rotor with internally cut teeth meshing with an externally cut gear idler; a crescent shaped partition is used to prevent liquid from passing back to the suction side of the pump; a typical oil pump, characterized by… …
