Our flange rain gun sprinkler models irrigate large acreage of horticulture, fruit, corn, wheat, barley, canola, and potato crops. Every flange rain gun sprinkler in Kenya by Grekkon Limited is from 1-1/2” to 2” inlet diameter size.
Flange rain gun sprinkler specifications
- Material. Aluminium, brass and steel
- Nozzle sizes. 12mm, 16mm, 18mm and 20mm
- Diameter of spray. 35M to 40M for the 1-1/2” and 40M to 60M for the 2”
- Discharge volume. 15 cubic to 30 cubic for the 1-1/2” and 20 cubic to 45 cubic per hour
Note that the diameter of spray and discharge volume is a factor of the nozzle size and pump capacity (engine size, pressure rating and discharge rate)
How much is a flange rain gun in Kenya?
- 1-1/2” is Kes 55,000
- 2” is Kes 65,000
How to work with flange rain gun requirements
i. Water availability. It requires 30 cubic per hour as a minimum. If irrigation takes 5 hours per day, then 150 cubic must be available
ii. Pressure. Check your growund elevation, determine your pressure loss in the system and your pipe size. Work backwards to determine the water pump type that matches your sprinkler choice
iii. Crop water requirement. This determines the time spent in irrigation
Your sprinkler will have a tripod steel support stand. The water delivery pipe is attached to the hollow bottom of the stand
The water drops are fine to use on flowering crops without causing flower abortion. On solanacious crops such as; tomato, potato, peppers, irrigate in the morning hours and not in the evening. This allows the moisture to dry off from the leaves, which minimises blight infection.
Before installation, our technical team makes a site visit to make the system layout plan. This is important to ensure that every inch of the farm is covered during irrigation and that there are no dry ‘shadows.’
These giant sprinklers irrigate over a short period of time, in a large area.
