Senninger (Wobbler) sprinklers and pressure regulators

Senninger has been a dedicated supplier of agricultural irrigation solutions for over 59 years. Their innovative water application products are designed to effectively address the irrigation needs of farmers, providing crop solutions for centre pivot irrigation, nurseries, and greenhouses. Their extensive range of products is essential for ensuring successful (fruit) crop growth through proper field irrigation. Additionally, their pressure regulators help conserve water and energy, enabling farmers to maintain desired performance and consistent pressure to their sprinklers. Choose Senninger for high-quality agricultural irrigation solutions that improve crop yields and save resources.

Spread water in an instantaneous, uniform pattern

Efficient water application

59 years experience

Save water and energy

Senninger's Wobbler Technology, first introduced in 1978, is a groundbreaking innovation in the world of sprinklers that offers both water and energy savings. These highly efficient sprinklers are renowned for their ability to spread water uniformly across a large diameter with very low operating pressures.

  • They go up from 0.7 bar to 2.0 bar
  • Low operating pressure
  • Uniformity over a large diameter
  • Resistant to high winds and temperatures
  • Prevents over-watering and run-off

Frost Protection for Crops

Senninger's Wobbler® technology helps protect crops from frost through agricultural irrigation. Overhead sprinklers apply water uniformly to the entire plant, helping prevent plant tissue from losing heat energy and possible damage. Overhead irrigation provides the highest level of protection compared to most available systems, and Senninger's Xcel-Wobbler™ and mini-Wobbler™ use less water than conventional impact sprinklers.

Control the pressure

Pressure regulation is essential for achieving the intended distribution pattern and application rate. Pressure regulators can automatically adjust their opening area as water enters the device at fluctuating pressures to help ensure the outlet pressure stays at a relatively constant level. To select the right pressure regulator model, you need to consider the sprinkler pressure requirements and maximum inlet pressure, sprinkler flow that falls within the regulator's designed flow range, inlet, and outlet connection size.

Irrigation for nurseries

One of the key goals of an irrigation system for nurseries is to achieve high uniformity in water distribution. Senninger offers a range of sprinklers that can achieve this goal, taking into consideration factors such as spacing, operating pressure, and application rate. The sprinklers can deliver an average application rate of approximately 0.5 in/hr (12.7 mm/hr), which is ideal for most nursery plants. Senninger's irrigation systems can help improve plant growth, reduce water waste, and save time and labour costs.

Frequently asked questions

What is uniformity? Why is it important?

Uniformity is the ability of an irrigation system to apply water evenly across the soil surface. If an irrigation system has poor uniformity some plants won’t get enough water, some will get too much, and excessive water will leach below the root zone and be lost. In order to adequately irrigate all plants in a field with an irrigation system that has poor uniformity, excess water must be applied. This is wasteful and expensive.

What is LEPA?

LEPA (Low Energy Precision Application) irrigation is a water-efficient irrigation practice that uses low-pressure bubble applicators to deposit water gently from a height of 8 to 18 inches (20 to 46 cm) above the ground, reducing wind and evaporation loss. Compared to conventional spray heads, at least 20% more water reaches the soil surface with LEPA sprinklers.

Do I need a pressure regulator for drip irrigation?

It is recommended to use a pressure regulator for drip irrigation. Drip installations operate at relatively low pressures, and even minor pressure variations can significantly affect how evenly the system applies water to the crop. Pressure regulators help maintain a constant pressure and flow rate, resulting in uniform water distribution throughout the system. They also help reduce system strain and prevent drip lines and fittings from blowing apart.
