Center- Pivot Irrigation Machine

We are Making and Exporting Center- Pivot Irrigation Machines in Shijiazhuang, Hebei, China.

Equipment running track:

Circular(D). One end of the equipment is fixed in the ground. The motor section connects with the type section and rounds about its center point. Water flow from the center point and then spray from the evenly distributed sprinkler head on the equipment. Because of the circular track, it also is called circular sprinkler, and circular machine for short.


Equipment length:

The span length is 54.5m or 61.3m: the length of the cantilever is from 8m to 28m (4 different choices); the tail nozzle can be optional. Different number and length of span, cantilever and tail nozzle to get the irrigation radius as customers' requirements. The upper limit of the length is 500 meters.


Electricity and water supply:

Electricity supply mode: buried cable and generator set.

Water supply mode: buried pipe and water reservoir.


Span parameters:

Pipe diameter: 141/ 168/ 203/ 254mm;

sprinkler spacing : 0.76/ 1.25/ 2.23m;

through height : 3.25/ 3.4/ 3.9 /4.9m;

flange thickness :10mm;


Main features:

Compare with the other irrigation method, it is more durable and sturdy irrigation uniformity, save energy and labor. Compare with the large lateral move system, the land utilization is 78%. Its low cost of purchase, operation and management. Supporting facilities is simple. Irrigation cycle time is shorter.
