An impeller is a rotating component of a centrifugal pump, usually made of iron, steel, bronze, brass, aluminum or plastic, which transfers energy from the motor that drives the pump to the fluid being pumped by accelerating the fluid outwards from the center of rotation. The velocity achieved by the impeller transfers into pressure when the outward movement of the fluid is confined by the pump casing. Impellers are usually short cylinders with an open inlet (called an eye) to accept incoming fluid, vanes to push the fluidradially, and a splined, keyed or threaded bore to accept a drive-shaft.
The impeller made out of cast material in many cases may be called rotor, also. It is cheaper to cast the radial impeller right in the support it is fitted on, which is put in motion by the gearbox from an electric motor, combustion engine or by steam driven turbine. Therotor usually names both the spindle and the impeller when they are mounted by bolts.
Our ventilators are with fantastic fan with excellent performance and elegant shape for circular pipe. With the perfect match between new designed shell and backward centrifugal impeller, our ventilators have the best pneumatic and hydrodynamic performance as well as compact size and practical application, our ventilators are easy to be installed, lightweight, quiet, and able to provide strong power for air feeding, exhausting, returning and purifying. With extremely high pressure, our ventilators can be used for a pipe over several decameters long, able to control multiple areas by one ventilator and can be applied to buildings, indoor air exchanging and pipe pressurizing. Air intake and outlet are designed in compliance with standard pipe diameters and can be connected to a pipe directly at both ends. Our ventilators are wildly used in public places like hotel, hall, conference room, supermarket, station, airport, etc.
