A pump is used to move fluids by using forces like air. Air moves forward from the way because the moving element starts to move. Generally, these are activated with electric motors that drive a compressor. Thus, a partial vacuum can be created because of the water movement, later it is filled with additional air.
How are pump and motor connected?
Pumps often taken directly coupled to the motor. In pump and motor coaxial connection can not be the case, the vast majority are connected by means of flexible coupling. Use flexible coupling, allowing a little misalignments (both axis of the angle or parallel) between the motor and pump shaft.4 ago 2016
