Product Description

The original and most used style of pivot irrigation applies water in a circular pattern, pivoting around a central point in the middle of the field. A pivot system consists of a lateral, stainless steel pipeline mounted across adjacent, mobile truss structures that support the pipe. Each truss is mounted on motorized wheels, allowing the entire length of pipe to move through the field.

 

Meanwhile, the growing use of farm management software allows farmers to monitor and capture their irrigation records, including analytics like use frequency, costs and ROI results. Farm management software like AGRIVI helps farmers better manage the sustainability of any type of irrigation system and assess the economic trade-off between installing a center pivot versus other irrigation systems such as flood irrigation, sprinklers or drip and micro-irrigation.
 

 

Center pivots are adaptable to different terrains and can be used in fields with up to a 30% slope, although 15% is recommended. They can even be used across rolling terrain, making center pivot systems accessible for many agricultural regions. This also means farmers don't have to move dirt, do field leveling or build the levee and dikes needed for flood irrigation systems.
 

Before motorized well pumps, water was drawn out of shallow wells pumped by hand or run by windmills. Motorized pumps allowed wells to be dug deeper and much more water to be pumped out at greater and faster volumes. Rapid expansion of motorized pumped groundwater wells happened around 1945, especially in areas located over aquifers with appropriate agricultural soils.

Nelson Sprinkler nozzles are installed along the pipeline or hang down from the lateral pipe on smaller pipes or cables. Flow rates and gallons per minute (GPM) can easily be adjusted in a center pivot system and pressure regulators can be utilized to create either a high-flow or low-flow system depending on water use needs.
 

The largest irrigation covering.
    No need digging or much earthwork, only water recourse like well or surface water, one single pivot could cover 1200acres within a short time. Bigger field, smaller investment.
 Highest mechanical and automatic irrigation way. 
     One single labor could manage 10000acres field, as far as increasing productivity.
Water saving 30%~50%,  spray uniformity reach 90%, adjust field climate, 20%~50% increasing of productivity is approved obviously.
Equipping with other agriculture machine to achieve irrigating, seeding, fertilizing,  gathering in one step

1.What kinds of pivots do fenglian produce?
Our products can be classified into three categories: fixed center pivot, towable center pivot, and lateral move system.
The main difference between these systems is their mobility.
1.The fixed system has one stationary end of the machine, while the other moves clockwise by motorized wheels.
2.Towable pivots have three or four wheels assembled at the center of the pivot, making it towable by tractor.
3.Lateral move systems work in a linear fashion, driven by motorized wheels. Unlike center pivots, where area is determined by the length of the machine, lateral move systems depend on both system length and distance traveled.A towable center pivot should be a maximum length of 300m for safe towing, but fixed pivots can be much longer.
Compared with both fixed and towable systems, lateral move systems depend on the source of water. Ditch fed machines recieve water from the built ditch. Hose fed machinery recieves water from underground pipelines with hydrants. For hose fed systems, the maximum length is 450m because connecting one hydrant to another incurs labor costs.
2.PIVOT DESIGN CHOICES
When purchasing a center pivot system one must select:
 Mainline size and outlet spacing;
Length, including the number of towers;
Drive mechanisms;
Application rate of the pivot;
The type of water applicator.
These choices affect investment and operating costs, irrigation efficiency, and crop production. Wise decisions will result in responsible water management and conservation, flexibility for future changes, and low operating costs.
3.What is the warranty on your products?
Warranty covers our center pivot and lateral move systems up to 1 year concerning electrical equipment, and 10 years or 10,000 working hours for gearboxes and gear motors-whichever expires first.
We guaruntee 15year use concerning our galvanized eqipment against corrosion, and 3 years for our tires and rims.
4.How much does your equipment cost?
Our pricing depends on the machine you are looking for, along with several other variables. In regards to our center pivots, we have both fixed and towable pivots and lateral move systems available. We will need to know your preferred water source (ditch or hose fed), land data and the types of crops that will be irrigated. Given this information, we will also determine the necessary sprinklers for your system.
