Pumps generally than the speed in the 30~300 runoff type, 300~500 use of mixed flow, more than 500 of the use of axial flow.
But can not be divided than speed, because some than speed can be used in this form can also be used in that form, the key is to see which form is better.
Centrifugal pump, axial flow pump mixed flow pump into the pump as design parameters can be divided according to specific speed. Specific speed centrifugal pump from about 30 to 300, from about 350 to 600 mixed flow pump, axial flow pump is greater than 600.
From the liquid flow to see; centrifugal pump inlet and outlet into a 90 degree angle, axial flow pump inlet and outlet into 180 degrees. Mixed flow pump, also known as the diagonal flow pump outlet and inlet into a certain angle. Of course, not to be exported.
Look at the impeller structure; centrifugal pump impeller for radial, axial inflow, radial water.
Axial flow pump impeller axial inflow, axial water.
Mixed flow pump axial inlet, outlet and axis has a greater than 90 degrees.
