Advantages of gear Sprinklers
With throw ranges of 7-12 meters, Hunter's gear-driven sprinklers easily irrigate even large lawns. Gear-driven sprinkler units allow you to adjust the sector from 50° to 360° directly at the nozzle head, as well as the throw distance by varying the nozzle (a set is included) and water pressure. A robust construction, a reliable sealing system and a powerful return spring permanently ensure the functionality of your irrigation system. The gear unit has a mechanism that protects against accidental adjustment, damage and interference by vandalism.
The Hunter I-20-04-SS (Plug&Rain® PREMIUM) stainless steel riser maximizes the life of your irrigation system and is especially recommended for sandy, abrasive soils. The new FloStop®-control shuts off water flow to individual sprinkler heads when needed during operation. This makes it easier to replace the nozzles and can also be used to temporarily not irrigate individual sectors. An outlet shut-off valve prevents puddling caused by uncontrolled emptying of the lines after watering times.
Installation instructions for gear Sprinklers
For uniform watering, a head-to-head installation should be provided for in the planning. Only one type of irrigation is ever connected per irrigation circuit. Gear sprinklers have considerable water consumption when using a large nozzle. The available amount of water in your water supply must therefore be checked carefully. You can perform this check with our measuring device. For this reason, geared sprinklers are particularly suitable for use with a well.
Spraying range and precipitation amount are adjusted by the choice of the enclosed nozzles. These values are influenced by water pressure and set irrigation sector. This adjustment is made with the Hunter Gear Sprinklers using the Hunter Adjustment Wrench ZZ-HT172000.
Another tip from a professional - Calculating the precipitation of geared sprinklers
With geared sprinklers, the precipitation rate changes by the choice of nozzle and by the set irrigation sector. In order for a gear sprinkler with a 180-degree sector to achieve the same precipitation as a 90-degree sector, the nozzle of the 180-degree sprinkler must deliver twice as much water in the same time. Caution: Due to the built-in discharge stop valve, Hunter gear sprinklers must be blown out with compressed air for winterization.
