Impeller pitch explained
WitrynaAn axial-flow pump, or AFP, is a common type of pump that essentially consists of a propeller (an axial impeller) in a pipe.The propeller can be driven directly by a sealed motor in the pipe or by electric motor or petrol/diesel engines mounted to the pipe from the outside or by a right-angle drive shaft that pierces the pipe.. Fluid particles, in … Witryna23 wrz 2010 · "Pitch" Explained - "Pitch" Refers to the degree of angle of the impeller blades. Straight pitch impeller blade is angled the same from the front of the hub to the rear. Progressively pitched impellers change angle from the front to the rear. A lower number impeller produces more low end RPM, thrust and acceleration which will …
