1. Rocker Arm Nozzle
The oscillating sprinkler is a commonly used irrigation device for outdoor spaces, serving as an essential watering tool in irrigation systems. This type of sprinkler boasts advantages such as balanced force distribution, reliable and stable operation, a relatively long spray range, and a wide flow-adjustment capability. Widely applied in landscaping irrigation, fruit and vegetable gardens, and horticultural sites, the oscillating sprinkler delivers consistently stable performance. It can be integrated into fixed, semi-fixed, or mobile sprinkler systems, offering medium-to-long-range coverage with steady operation and high uniformity. Available in three materials—solid copper, zinc alloy, and plastic—it supports both full-circle and customizable fan-shaped spray patterns.
II. Buried Rotary Nozzle
The underground rotary sprinkler is currently the most widely used type of sprinkler in landscape irrigation. Its primary operating principle involves water flow driving an internal impeller inside the sprinkler, which in turn rotates gears, causing the sprinkler head to spin steadily as it sprays. That’s why the underground rotary sprinkler is also known as a gear-driven sprinkler. These sprinklers feature a relatively large spray radius—ranging from 5 to 25 meters depending on the specific product model—and some specialized, larger-caliber models can even achieve a spray radius exceeding 30 meters.
3. Buried Scattering Sprinklers
The buried-type diffuser nozzle is a low-pressure, short-range sprinkler designed primarily for small lawns and green spaces supplied by standard tap water systems. Typically made from engineering plastic and stainless steel, it offers excellent corrosion resistance. It’s easy to install and highly durable against corrosive elements. The spray pattern features well-defined edges, helping minimize water waste while delivering consistent spray intensity. This versatile product is widely suitable for lawn landscaping, rooftop cooling, and other similar applications.
4. Buried Radiant Nozzles
In recent years, subsurface radial sprinklers have gradually gained popularity as a non-traditional irrigation method. Their biggest advantage lies in the ease of adjusting both the spray angle and range, helping to minimize unnecessary over-spraying. Compared to subsurface diffused sprinklers, radial sprinklers deliver a significantly lower flow rate. For instance, at the same spray radius of 5.5 meters, a diffused sprinkler with a 360° full-circle spray pattern delivers a flow rate of 1.21 m³/h per nozzle, whereas under identical conditions, a radial sprinkler produces only 0.3 m³/h. Additionally, radial sprinklers create a sleek, linear spray pattern that not only looks visually appealing but also enhances the overall landscape aesthetic.
