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 Pancake for small range production capacity Francis Mixed flow , usually for high production pump Mixed flow
Impeller & Curves
Typical Performane, Efficency & Thrust Curve
Pumps 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.
