Description
Our raingun sprinkler price in Kenya is for the new generation of high-volume, high-pressure raingun sprinklers in Kenya. Our low-pressure raingun sprinkler specification is 1” in diameter, with a throw of 12M in diameter. The larger ones require high pressure. Raingun sprinkler irrigation cost is lower than a drip system at the point of installation. However, raingun sprinklers are more expensive to run than a drip irrigation system because they require a pump, and a consume large volume of water, while the latter will work with gravity flow, and low water volume Rain gun pipes are; PVC or HDPE or delivery lay flat pipes, whose use is described in detail below

Cost per acre (installation cost)
The cost of a sprinkler system in Kenya is from Kes 65,000 an acre without the water pumping system. It varies with the types of rainguns and size. Before we install a raingun sprinkler system in a farm, a site assessment visit is carried out to determine;- the appropriateness of this overhead irrigation system to the crop
- the farm terrain
- amount of water available
- the water pump specs where one exists

- Flange raingun
Grekkon Limited introduced a new model of the raingun sprinkler to the Kenyan market; the double nozzle steel and brass raingun series.
These raingun specifications are; 2 nozzles, a main top nozzle of 16mm, and a small underneath nozzle of 8mm. The purpose of the small nozzle is to eliminate any water shadow areas or sections within the irrigated farm that remain dry.

- Pasture crop. lucerne, Rhode grass5, and all other pasture grass
- Herbs. mint, lemongrass, geranium, tagete, and so on
- Hedge plants. kei apple, bougainvillea, cypress
Is raingun good for irrigation?
Crops that are easily susceptible to fungal infections as a result of dampness on their leaves such as tomatoes and peppers are better irrigated using the drip irrigation system method
Our RG sprinklers work best at a pressure rating of 30M to 40M head or 3 bars to 4 bars of pressure. When determining a suitable water pump to power these sprinklers, one must consider the water discharge rate and the pressure rating. The water pump must meet these specs. When connecting say 2 RGs of 2″ each to a water pump, the water discharged by the pump will be 15 cubics per hour by 2 units so 30 cubics per hour. The water pump water discharge specs must meet this specification. This however does not factor in frictional losses, which are determined by the; pipe diameter, the total horizontal and vertical pumping distances
Our flange type rainguns come with different detachable nozzle sizes

FAQs
A. How do you install a raingun?
- Lay the mainline which is connected to your high-pressure water pump
- Lay and connect the lateral or sub mainline to the mainline
- Connect the raingun sprinkler to the sub mainline using a delivery lay flat pipe, an HDPE pipe or PVC pipe
B. How do you design a raingun irrigation system design?
The input pipe will be; PVC, HDPE, PPR, or a delivery pipe. Since the sprinklers work under high pressure, each of these pipe’s pressure rating should be a PN8 at the minimum. Each rain-gun sprinkler has a 1M steel tripod stand for support. The sprinklers can be manually adjusted to spray at any angle from 10 degrees to 360 degrees
C. Can I use a booster pump for the raingun?
Booster pumps for water gun irrigation work well when drawing water from a tank. Use it with the 1″ raingun
D. How do I assemble a raingun irrigation system?
i. Check that your raingun sprinkler has no damaged or loose parts
ii. Connect the raingun head to the tripod stand
iii. Attach a PVC, HDPE, or delivery pipe to the raingun sprinkler inlet at the base
iv. Adjust the water gun sprinkler to the desired angle of irrigation water delivery
v. Start your irrigation water pump
E. How much area does a raingun sprinkler cover?
This depends on the inlet size, type of RG sprinkler, pressure rating and flow rate. The table below provides details
| Type | Make | Inlet Diameter | Max Spray Diameter | Min Head (Pressure Rating) | Max Flow Rate |
| Flange (F) | Metallic (M) | 2″ | 60M | 40M | 60M3/ Hr |
| F | M | 1.5″ | 45M | 40M | 40M3/ Hr |
| PY 50 | Metallic | 2.5″ | 40M | 30M | 25M3/ Hr |
| PY 40 | Metal | 2″ | 35M | 30M | 17M3/ Hr |
| PY 30 | Metallic | 1.5″ | 30M | 30M | 8M3/ Hr |
| RM | Metal- Brass | 1.5″ | 30M | 30M | 8M3/ Hr |
| Plastic | Plastic | 1.5″ | 30M | 25M | 7M3/ Hr |
| RM | Metallic | 1″ | 20M | 30M | 6.5M3/ Hr |
| Plastic (P) | Plastic- Hard Black | 1″ | 12M | 10M | 3M3/ Hr |
| Plastic | P | 3/4″ | 7.5M | 10M | 2M3/ Hr |
| None Metallic | Plastic | 1/2″ | 5M | 10M | 1.5M3/ Hr |
When procuring a rain gun sprinkler, it is important to understand this tabulated information so a to settle on the most appropriate type
F. How much horsepower (Hp) does a raingun sprinkler need?
This depends on the inlet size of your rain gun sprinkler, the larger it is, the greater the water discharged, and so the more horsepower required 1″ and 1.5″ from 8.5Hp 2″ and 2.5″ from 10Hp

How To Choose Your Raingun Sprinkler
- Diameter of spray. The choice of diameter of spray is determined by the acreage under irrigation. A grower with 10 acres will pick a larger diameter of spray than to a 1/4 acre farmer because s/he has a larger coverage.
- Flow rate. The flow rate preference is a factor of the crop type because different crops have different needs. A livestock farmer will grow his grass pasture well with a lower flow rate than a vegetable horticulture farmer. This is because the vegetables require much more water than grass. Another contributing factor to flow rate is the amount of water present, both must be aligned to avoid drying up the water source
- Pressure rating. This determines the water pump size to use with the sprinkler. The water pump’s head must be greater than the sprinkler’s to accommodate pressure losses during reticulation
