2. Pump: A machine for adding energy to fluid

3. ...causing it to defy gravity

4. Energy in • Pressure and flow out

5. Trade-off: Your thumb over a garden hose

6. Main pump types
 Positive displacement
 Pushers
 Centrifugal
 Spinners

7. Positive displacement physically pushes the water

8. High, consistent pressures & specific volumes

9. Centrifugal pumps create pressure differential

10. Low pressure at eye, high pressure at discharge

11. Most collection system pumps are centrifugal

12. Impeller versus propeller

13. Containing the action of an impeller

14. Wearplate, impeller, shaft, sealplate, & seal

15. Three primary styles of centrifugal pump

16. Flooded suction

17. Submersible

18. Self-priming

19. Safety matters: Deadly gases

20. Safety matters: Falls

21. Safety matters: Electrocution

22. Always use the safest available pump

23. Where a flooded suction makes sense

24. Where submersibles make sense

25. Where self-priming pumps make sense
