Rain gun Sprinklers
Our rain gun sprinklers for sale in Kenya specifications are of the new generation of high-volume, high-pressure rain gun sprinklers in Kenya. Our low-pressure rain gun sprinkler specification is 1” in diameter, with a throw of 12M in diameter
The larger ones; from 1-1/2″ throgh 2-1/2″ require high pressure. Rain gun sprinkler irrigation cost is lower than a drip system at the point of installation. However, rain gun sprinklers are more expensive to run than a drip irrigation system because they require a pump, while the latter will work with gravity flow. The cost of a rain gun sprinkler system installation is comparable to that of a rain hose kit
Rain gun pipes are; PVC or HDPE or delivery lay flat pipes, whose use is described in detail below.

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 rain guns and size. Before we install a rain gun 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

Types of Rain Gun Sprinklers In Kenya
Our rain gun sprinkler types are;
- PY series. PY 30, PY 40, and PY 50
- Plastic
- RM
- Flange rain gun
Grekkon Limited introduced a new model of the rain-gun sprinkler to the Kenyan market; the double nozzle steel and brass Rain-gun series.
These Rain gun 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.
How to use a rain gun; choice of crops to irrigate
- Horticulture. cabbage, spinach, kales, carrot, onion, garlic, strawberry, and pineapple
- Broad-acre crops. wheat, barley, canola, sugarcane, and corn/ maize
- Fruit orchards. citrus (orange, tangerine, and lemon), avocado, macadamia, papaya, guava, mango, tree tomato, and passion
- Forestry. seedlings and mature trees
- Pasture crop. lucerne, Rhode grass5, and all other pasture grass
- Herbs. mint, lemongrass, geranium, tagete, and so on
- Hedge plants. kei apple, bougainvillea, cypress
- Lawns
Are rain gun sprinklers 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 rain guns come with different detachable nozzle sizes
FAQs
A. How do you install a rain gun sprinkler?
- 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 rain gun sprinkler to the sub mainline using a delivery lay flat pipe, an HDPE pipe or PVC pipe
B. How do you design rain gun irrigation sprinklers system?
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 rain gun?
Booster pumps for water gun irrigation work well when drawing water from a tank. Use it with the 1″ rain gun.
D. How do I assemble a rain gun irrigation system?
i.Check that your rain gun sprinkler has no damaged or loose parts
ii. Connect the rain gun head to the tripod stand
iii. Attach a PVC, HDPE, or delivery pipe to the rain gun 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 rain gun 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 |

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 rain gun 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
G. What pressure is needed for a rain gun?
From a head of 30M or 3 bar
H. What is the difference between a sprinkler system and a rain gun?
A rain gun is large and covers a large area, thereby replacing several impact or pop up sprinklers
A porateble 16Hp engine, moderate pressure, high volume diesel water pump on display at Grekkon’s Athi River warehouse. This works pretty well with any raingun sprinkler
I. What size are rain guns?
1″, 1-1/2″, 2″ and 2-1/2″
J. What are the benefits of rain gun?
- It irrigates over a large swathe of farm land
- It irrigates over a short period of time due to its high water volume
- Chemicals and fertilisers can be aapplied via this sprinkler
- It is east to move about
- It is easy to assembly and disassemble
K. How much motor is required for a rain gun?
For electric pumps, motors from 2Hp will run these sprinklers depending on the size of the pump
L. What crops are irrigated by rain guns?
Vegetables, tree crops, lawns, pastures, and turf grass in sports arenas
How To Choose Rain Gun Sprinklers
- 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

How can a rain gun be used to irrigate tall grown maize say tasseling and flowering stage height

How many sprinklers will I need for 1/2 acre ? I have a well, can I use water from it ?…..which pump would you recommend to be used to draw water from the well and pump it to the sprinklers? Thanks
Dear Obodo,
One rain gun sprinkler of 1-1/2″ is enough. A high-pressure diesel or petrol generator pump will suction water up to 7M from your well. So if the water level is deeper, then you’ll need a submersible pump to evacuate it to a storage unit from which a generator petrol/ diesel or electric surface pump will pump from

It work well I really admired it thank
Thank you!
Just wanted to enquire can spinach be irrigated well by use of sprinklers
Hey Matin,

Can french beans be irrigated by the double gun. Half acre will require how many pumps.
Dear George,
It is possible to do so but we advise against the rain gun sprinkler because French beans are highly susceptible to blight and rust as a result of excess moisture on their leaves. Drip irrigation is the best for this crop.
