1. Sprinklers

2. Nozzles
Controls distance and flow
Interchangeable

3. Operating pressure PSI – pounds per square inch
Rotary sprinklers: 35 to 45 psi
Sprayheads: <30 psi

4. Flow GPM (Gallons per minute) Controlled by nozzle size and PSI
Larger nozzles have greater flow and require greater PSI

7. Radius
Distance from the head
Increases with PSI and nozzle size

8. Water distribution pattern
Uniformity around sprinkler
Head-to-head spacing

9. Arc
Portion around sprinkler that gets watered

10. Trajectory
Angle above ground
Low trajectory
Wind
Under trees

11. SPRAY HEADS
No moving parts, except pop-up
Small areas
8’ to 15’

12. SPRAYHEADS

13. Blow-out Nozzles Purge debris from pipes
Pull up riser to install nozzle

14. Fixed Spray Nozzle Have matched precipitation rate (MPR)
Flow matched to arc
Q = 1 gpm
H = 2 gpm
F = 4 gpm

15. VAN Nozzle

16. Color-coded Nozzles
Buy nozzles separately

18. Pressure Regulating Screens

19. Rotary Nozzles
Fit on sprayhead body

20. Rotary Nozzles
Low drift
Pressure compensating

21. ROTARY SPRINKLERS
Rotating stream
Large areas
15’ to 100’

22. ROTARY SPRINKLERS
Gear-driven sprinklers

23. Gear-driven Sprinklers
Nozzle tree

24. Small Rotary
15’ to 25’

25. Standard Rotary
22’ and 40’

26. Interchangeable Nozzles

27. Interchangeable Nozzles

28. Interchangeable Nozzles

29. Adjusting Arc
One side is adjustable
The other side fixed

30. Gear-driven Sprinklers
Break-up screw
Shorten radius
Holds in nozzle

31. ROTARY SPRINKLERS Impact sprinklers
hammer to move sprinkler, makes the sprinkler sound

32. Impact Sprinkler

33. Valve-in-Head Sprinkler
Gear-driven sprinkler
Valve in bottom

34. Valve-in-Head Sprinkler

35. Swing Joint

36. Swing pipe

37. Swing pipe

38. Swing pipe

39. Pressure Regulating Sprinklers
PRS
No matter what PSI goes in sprinkler, a specific PSI comes out
All sprinklers run at same PSI
Prevents over PSI

40. Check Valve Installed in bottom of sprinkler
Prevents sprinkler from weeping after it runs due to elevation
