Flange Rain Gun Sprinkler

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

1. Material. Aluminum, brass, and steel
2. Nozzle sizes. 12mm, 16mm, 18mm, and 20mm
3. The diameter of spray. 35M to 40M for the 1-1/2” and 45M to 60M for the 2”
4. Discharge volume. 15 cubic to 30 cubic per hour for the 1-1/2” and 20 cubic to 45 cubic per hour for the 2″

 

 

Note that the diameter of spray and discharge volume is a factor of the nozzle size and diesel or electric pump capacity (engine/ motor size, pressure rating, and discharge rate)

 

How much is a flange rain gun in Kenya?

1. 1-1/2” is Kes 55,000
2. 2” is Kes 65,000

This cost is inclusive of the steel tripod stand

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 ground elevation, determine your pressure loss in the system and your pipe size. Work backward to determine the water pump type that matches your sprinkler choice. The frictional losses along the pipeline will be taken into consideration too

iii. Crop water requirement. This determines the time spent in irrigation

 

Summary

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 solanaceous crops such as; tomatoes, potatoes, 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.
