Axial Flow Pump Diagram

An 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.

Axial flow pump diagram. Axial flow pumps are sometimes called propeller pumps because they operate essentially the same as the propeller of a boat. The image above shows a typical performance curve for an axial flow pump depicting the relationship between head flow rate power and efficiency. However from the outside looking in axial flow pumps look a lot like turbines so we ve included them in this category. Axial piston pumps are used to power the hydraulic systems of jet aircraft being gear driven off of the turbine engine s main shaft the system used on the f 14 used a 9 piston pump that produced a standard system operating pressure of 3000 psi and a maximum flow of 84 gallons per minute.

Fluid particles in course of their flow through the pump do not. As shown in the diagram the shut off zero flow head of an axial flow pump can be as much as three times the head at the pump s best efficiency point. 1 schematic diagram of axial flow pump and impeller the water from the sump well is sucked into the suction pipe in an axial direction and passed through the runner vanes impeller and finally discharged through another set of guide blades into the delivery pipe. Axial flow pumps are low head high flow designs and aren t true turbines.

Axial flow pumps are typically designed for heads no greater than approximately 30 ft and are often designed to lift water just a dozen feet. Hydroflo pumps manufactures assembles and delivers the most dependable purpose engineered pumps on the market including all stainless steel zero lead turbine pumps. Below are downloadable axial flow pump curve cut sheets showing the tdh and gpm at set rpms. In an axial flow pump the impeller pushes the liquid in a direction parallel to the pump shaft.

The impeller of a typical axial flow pump and the flow through a radial flow pump are shown in figure 7. Layne bowler low head pumps are ruggedly designed for long years of trouble free continuous. Axial flow is a common type of pump that essentially consists of an impeller in a pipe operating in a casing. We serve the agricultural commercial and municipal markets plus specialized markets such as mine dewatering and nuclear plant cooling towers.
