A pump in which the pressure is imparted to the fluid by centrifugal force produced by a rotating impeller. centrifugal fan
A nonpositive-displacement pump in which the liquid-propelling parts are paddle wheel-like devices rotating within a case and generally capable only of delivering large volumes of liquid at low pressures. compare duplex pump, rotary pump, triplex pump.
A pump with a rotating element, shaft and impeller and a stationary casing. in this pump, fluid is propelled at high velocity as centrifugal force at the periphery of the impeller blades discharges pressurized fluid into the system.
