The mini sprinklers mechanism is using a dynamic spinner, which is also the nozzle seating on a column which allows the spinner nozzle to spin. When water passes thru the nozzle it spins the spinner, which throws the water in a full circle to the diameter determined by the flow rate, pressure and the angle of the water leaving the spinner.
When low volume overhead irrigation is desired for an areas where drip emitters are not practical, the mini sprinkler, one of the micro sprinklers family can throw the water over wide area and can be used to water under tree canopy, seedlings, germination, flowerbeds, groundcover, young saplings, mature trees, in greenhouses and nurseries. The mini sprinkler operates at low pressure and have a wide range of flow rates with 10 to 42 GPH and diameters with 6 to 17’ of a full circle pattern. The mini sprinkler has a small droplets and low flow application rate. One of the main features of the min-sprinkler is that it can prevent plant stress by maintaining low water tension in the soil, using a low flow application rate.
One of the main features of micro sprinklers system is the range of the application rates. Using a micro sprinklers an application rates can vary widely from 0.05 inches/hour and up. Because there is a direct relation between application rate and irrigation duration, there can also be a range in the duration to complete an irrigation cycle. For example, 8 minutes is required to apply 0.4 inch of water with an application rate of 3 inches/hour, while 8 hours is needed to apply the same amount at a rate of 0.05 inch/hour. This range of rates is readily available using micro-sprinklers...

• Installation for Mini Sprinklers

  To install the 360 degree mini sprinkler use the complete assembly with spike micro tubing and barb. To replace the head of the mini sprinkler, pull the head with the nozzle out of the assembly and replace with a new head with nozzle. Make sure to flush the line before inserting the new head with the nozzle, no tool or glue is required.

  To install the mini sprinklers, first select the flow rate and the mini sprinkler diameter. Use the assembly with the spike and the micro tubing by first inserting the spike into the ground for about 2-4”, then punch a hole into the side of the drip tubing using a punch and then insert the barb on the micro tubing into the drip tubing.
