Course 5 - Pump Selection

NOTE: Participants are expected to know Pump Fundamentals 101 with knowledge of pump curves and basic theory of how different pumps work.

Course Outline:

Picking the correct pump type for specific applications:

• What type of pump to pick for light hydrocarbon (ethane, propane, etc.)​
• Viscous applications (bitumen, cold crude, etc.)
• Light abrasive services (ore preparation area in oil sands mining, sump tanks, light slurry like lime or Magox)
• Low NPSHa applications (API Type VS6, when is a larger slow model applicable, what model has tolerance to run dry or better handle cavitation issues)
• Self-priming versus sump pumps (are modifications necessary)
• Low shear applications (positive displacement pumps)
• Run dry applications (multiphase, pad pumps, AODD, hydraulic diaphragm, sliding vane, lobe pumps)
• Low flow, high head applications

Sometimes there would be multiple types of pumps that could be selected, sometimes it would be limited. When not to use a certain type of pump is also important

Course covers:

• Horizontal centrifugal​
• Vertical centrifugal
• Inline pumps
• Regenerative turbines and side channels
• All types of reciprocating pumps
• All types of rotary positive displacement pumps

Application type case studies that have challenges could be reviewed, such as:

• Boiling fluids from a bullet,​
• Flare knockout drum service (VS4 sump pump, PC pump, and other low NPSHr pump types)
• Pipeline pump - variable suction pressure and flow
• Blending - constant discharge with variable flow
