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

Pancake Francis Mixed flow

Impeller & Curves

Typical Performane, Efficency & Thrust Curve

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.

HPS Considerations

 Quick Delivery - 8 to 12 Weeks  Low Capital Cost  Extended Run Life Increased Reliability & MTBF Low Maintenance  High Quality Standards  Modular Design Easy replacement & minimal “down-time” Easy to Re-rate in the future Minimal Spare Parts Inventory  Environmentally Friendly  Low Life Cycle Cost

Why use HPS?

 Reduced Radial Shaft Loads

Diffuser Style Advantage
