Reality vs. Model
 Don’t be confused! Spot the difference
vs.
 Helpful hint: think function, not form
 Head, flow, speed, logic
Pumps: Reality
 Pump Choices:
1.
2.
3.
4.
5.
Pump Location: submerged or dry
Displacement type: positive or centrifugal (or axial)
Motor speed: variable or fixed
Orientation: horizontal or vertical
Appurtenances: grinders, screens
