Intro to pumps in a collection system

  1. 1. INTRODUCTION TO PUMPS IN A COLLECTION SYSTEM Brian Gongol DJ Gongol & Associates, Inc. April 20, 2015 DMACC Collection Systems Class Ankeny, Iowa
  2. 2. Pump: A machine for adding energy to fluid
  3. 3. ...causing it to defy gravity
  4. 4. Energy in • Pressure and flow out
  5. 5. Trade-off: Your thumb over a garden hose
  6. 6. Main pump types  Positive displacement  Pushers  Centrifugal  Spinners
  7. 7. Positive displacement physically pushes the water
  8. 8. High, consistent pressures & specific volumes
  9. 9. Centrifugal pumps create pressure differential
  10. 10. Low pressure at eye, high pressure at discharge
  11. 11. Most collection system pumps are centrifugal
  12. 12. Impeller versus propeller
  13. 13. Containing the action of an impeller
  14. 14. Wearplate, impeller, shaft, sealplate, & seal
  15. 15. Three primary styles of centrifugal pump
  16. 16. Flooded suction
  17. 17. Submersible
  18. 18. Self-priming
  19. 19. Safety matters: Deadly gases
  20. 20. Safety matters: Falls
  21. 21. Safety matters: Electrocution
  22. 22. Always use the safest available pump
  23. 23. Where a flooded suction makes sense
  24. 24. Where submersibles make sense
