Axial-flow pump

An axial pump conveys the fluid axially, i.e. in parallel to the pump shaft (as opposed to the radial pump). Because the fluid is not ( as in the case of a piston pump ) carried as a closed volume, but rather by differences in pressure due to the movement, a part of an axial flow pump to pump the flow. In contrast to the radial pump the operating principle of an axial flow pump does not require reversal of the flow.

The axial flow pump consists of a tubular pump housing in which rotates the propeller-like pump impellers. Axial pumps are used when it comes to gentle handling. It is driven in large pumps mostly by a flow-around on the medium to drive gondola, in which engine and transmission are, or by means of a system established by a pipe bend shaft. It is also possible to drive purely magnetically an axial pump from the outside, this end is to the pump blades, an annular phase motor squirrel-cage attached. Around the tubular pump housing is the stator of the motor. This motor is hermetically sealed and suitable for aggressive or dangerous goods. The rotor bearings can also be made magnetic.

Axial or Mikroaxialpumpen be used as a blood pump for cardiac assistance.

Axial compressor rotor possess, carry the blade rings with up to several hundred blades. They are usually multiple stages and between the blade rings of the rotor are wreaths with blades, which along align the conveyor beam back to the compressor axis. Axial compressors are an integral part of aircraft engines, where they are needed to compress the air for the combustion chamber, as well as for the generation of mantle flow.
