Pumps
The HPS unit is a multistage diffuser pump; containing a selected number (application dependent) of impellers equipped with vanes, inside a closely fitted diffuser, located in series an axial shaft, driven by the electrical motor.
Radial / Francis / Mix-Flow Impeller Types Casing is radial split.
Stages
Each "stage" consists of an impeller and a diffuser. Again, the impeller takes the fluid and imparts kinetic energy to it. The diffuser converts this kinetic energy into potential energy (head).
Operation
Fluid enters through the intake, into the lower diffuser.
Impeller moves the fluid along the opening vane to the diffuser.
Diffuser directs the fluid direction up and changes the kinetic force into potential force or pressure.
Number of stage determine head developed, and also determines the horsepower requirement.
Radial Flow Stage
Discharges fluid at a 90° angle away from the rotation of the shaft
Higher head per stage compared to mixed flow pumps
Smaller vein clearance
Used for lower volume pumps
Mixed Flow Stage
Discharges fluid at a about 45° angle away from the rotation of the shaft
Lower head per stage compared to radial flow pumps
Large vein clearance
Used for high volume pumps
Impellers
Radial flow (Pancake), usually for small range production capacity
Mixed flow , usually for high production pump

Mixed flow
Pumps come in two basic varieties:
“Floater" construction - each impeller is free to move side to side on the shaft as it wants to so it is said to "float" on the shaft.
“Compression" construction - every impeller is fixed to the shaft rigidly so that it cannot move without the shaft moving. All the impellers are "compressed" together to make one rigid rotating assembly.
