Nozzles for micro hydro applications
Standard Nozzle sizes and flowrate table (.pdf) or spreadsheet (.xls)
$20 Series 70 (3/8″ NPT) nozzles (#12 to #20)
$40 Series 80 (3/4″ NPT) nozzles (#22 to #40)
$96 Series 125 (1-1/4″ NPT) nozzles, custom machined brass in 3/4″, 7/8″, 1″ or 1-1/8″ bore.
Nozzles include PVC fittings as shown in photos above.
Nozzle sizes are referred to by # which is the bore in 1/64″ increments.
Nozzles come in “series” which refers to the pipe thread size, 70 series (named for the sprinker size) is 3/8″ NPT sizes #12 to #20, 80 series is 3/4″ NPT sizes #22 to #40, and 125 series 1-1/4″ NPT #48, #56 and #64.
The nozzle sizes #22 to #40 ($24 each) are mass produced for agricultural irrigation sprinklers.
The 125 series are much larger, custom machined and come with fittings for 3″ hose/pipe.
Anything larger is custom welded and machined stainless pipe fittings and will be by quote.
Design Note: Supply line should be at least 3 times the nozzle diameter to reduce losses and maintain flows.
