100 meter rain gun price in Kenya start at KSh 4,000 for a 35 metre radius impact gun and reach about KSh 60,000 for a flange-inlet model in the shop guide. The 100 meter figure describes a wetting circle 100 metres across. That class needs a 2 to 2.5 inch gun running at higher pressure than a smallholding pump usually delivers.
This guide separates the two questions buyers mix up: what the gun costs, and what the pump, pipe and hose add. It also gives the flow and pressure figures that decide whether a 100 metre circle is realistic on your water source.
100 Meter Rain Gun Price in Kenya
Eunidrip stocks two rain guns in the online shop and lists three more sizes in the rain gun buying guide. The two shop models are the entry point. Both are impact guns, which means a spring arm breaks the jet into droplets and the head rotates on a bearing.
| Model | Wetting diameter | Flow | Pressure | Price |
|---|---|---|---|---|
| Impact rain gun, 35 m radius | 48 to 72 m, commonly 56 m | 10,000 to 25,000 L/h | 4 to 5 bar | KSh 4,000 |
| Gun Sprinkler, 1 to 2.5 inch | 40 m as listed | 8,000 to 50,000 L/h | Set by nozzle | KSh 8,500 |
| PY metallic, shop guide | 20 to 50 m typical | Model specific | Model specific | KES 14,500 |
| RM metallic, shop guide | 20 to 50 m typical | Model specific | Model specific | KES 17,000 |
| Flange metallic, shop guide | Largest listed | Model specific | Model specific | KES 60,000 |
The KSh 4,000 gun is the one most smallholdings buy. However, its 56 metre wetting circle is not a 100 metre circle. A farmer who needs the full 100 metres must step up to a larger inlet and a stronger pump.
The 35 metre radius gun is sold as a complete head with a tripod stand. It suits a quarter acre of pasture, an orchard row or a vegetable block. Also, it can be moved between positions by hand, which keeps the pipe run short.
What a 100 Meter Rain Gun Covers
A rain gun is sized by its wetting diameter, not by the length of its body. Therefore, a 100 meter gun throws water about 50 metres in every direction from the stand. The circle it wets is roughly 7,850 square metres, which is 0.78 hectares or about 1.9 acres.
That is a large area for one position. Because of this, a 100 metre gun is normally used on open pasture, fodder, orchards and plantation blocks rather than on garden beds. The jet is coarse and the droplets land hard, so young seedlings need either a smaller head or a raised stand.
Impact guns work by interrupting the jet with a spring-loaded arm. The arm swings back and forth and rotates the body in steps, which is what produces the even circular pattern. The Wikipedia entry on irrigation sprinklers describes how that mechanism developed, while this page keeps to what it means for a purchase.
Wind is the main limit on coverage. A 50 metre throw measured in still air can shrink by a third in strong afternoon wind, and the pattern becomes lopsided. As a result, spacing on exposed land should assume a smaller circle than the catalogue figure.
100 Meter Rain Gun Price in Kenya: 2026 Table
The table below separates the gun price from the parts that complete the set. The gun is the cheapest item in most installations. In addition, the pump usually costs more than the head, and the hose and stand add again.
| Item | Typical price | What it covers |
|---|---|---|
| Impact rain gun, 35 m radius | KSh 4,000 | Head and tripod stand |
| Gun Sprinkler, 1 to 2.5 inch | KSh 8,500 | Head only, size to be chosen |
| Flange metallic rain gun | KES 60,000 | Largest model in the shop guide |
| Suction and delivery hose | Quoted | Length and diameter decide it |
| Pump, 10 HP class | Quoted | Selected against flow and head |
A working set therefore lands well above the head price. For example, a 100 meter rain gun price in Kenya at KES 60,000 for the flange model. The pump, hose and fittings for that flow can add a similar amount again, so budget for the set rather than the head.
What Changes the Price of a 100 Meter Rain Gun
Five factors move a rain gun quote more than anything else. The first is inlet size, because a 2.5 inch body carries more water and costs more to cast than a 1 inch body. The second is material, since brass and treated alloy outlast plastic but cost more.
The third factor is nozzle size, which sets both flow and throw. A larger nozzle gives a longer throw but needs more water and more power. The fourth is the stand, because a fixed stand, a wheeled trolley and a tall tripod are priced differently. Finally, freight to the farm changes with distance and with the bulk of the set.
Flow rate ties all of these together, and it is the main reason 100 meter rain gun price in Kenya span such a wide band. A gun rated at 10,000 litres per hour can run on a small pump and a 25 mm line. However, a gun rated at 50,000 litres per hour needs a large bore delivery pipe. Otherwise, friction will eat the pressure before the water reaches the head.
Pump, Pressure and Horsepower
Horsepower is not a property of the gun. Rather, it is the result of the flow and the pressure the gun needs. The estimate below uses the standard pump formula. It assumes 55 percent efficiency, so treat it as a planning figure rather than a guarantee.
| Flow | Pressure head | Shaft power | Nearest motor |
|---|---|---|---|
| 10 m³/h | 40 m | 2.0 kW | 3 HP |
| 18 m³/h | 45 m | 4.0 kW | 5.5 HP |
| 25 m³/h | 50 m | 6.2 kW | 10 HP |
| 35 m³/h | 50 m | 8.7 kW | 12.5 HP |
Pressure at the head is the figure that matters. One bar is about 10 metres of head, so a gun rated at 5 bar needs 50 metres of head at the nozzle. Because of this, a pump rated at 5 bar at the outlet may deliver less. Pipe, elbows and the height of the stand all take their share.
Suction conditions decide whether the pump performs at all. A surface pump above a river lifts water through a suction hose, and that lift counts against the total head. Also, a long suction run with air leaks will cut output even when the pump itself is correctly sized.
Solar pumping is an option on sunny sites. However, the panels must be sized for the daily water volume, not for the peak flow. The irrigation equipment range covers the pump and panel combinations available.
How Many Guns Does an Acre Need?
The acreage a gun covers explains why 100 meter rain gun price in Kenya vary so much between models. One 100 metre gun covers about 1.9 acres from a single position, assuming no wind and a full circle. As a result, a five acre block needs three positions with overlap, not one. Overlap matters because the edge of a circle receives less water than the centre.
A smaller 35 metre gun covers about 0.7 acres per position. Therefore, the same five acres would need eight positions, plus a longer pipe run and more labour to move the stand. That trade-off is the real reason buyers ask for the larger gun.
The application rate follows from flow and area. For example, 25,000 litres per hour spread over 7,850 square metres is 3.2 millimetres per hour. A gun at 50,000 litres per hour doubles that to 6.4 millimetres, which is closer to the peak demand of a mature fodder crop.
Errors That Waste Money on a Rain Gun
The first error is buying the gun before measuring the water source. A borehole that yields 8 cubic metres per hour cannot feed a gun rated at 25 cubic metres per hour. In that case the pump runs dry or the jet collapses.
The second error is ignoring the delivery pipe. A long 25 mm line carries far less than a short 50 mm line, and the loss appears as weak pressure at the head. Because the pipe is invisible, buyers compare 100 meter rain gun price in Kenya head to head and forget that a cheap gun on a long thin line performs worse than a dearer gun on a short mainline. The sprinkler irrigation system guide explains how mainline size affects the whole block.
The third error is buying a 100 metre gun for a small plot. On a quarter acre, most of the water lands outside the crop. Instead, a 35 metre gun or a set of smaller heads gives better control and costs less to run.
The fourth error is skipping the stand. A gun lying on the ground throws a short, uneven pattern, and the gear will wear faster from grit. Finally, buyers often forget that a rain gun needs a dry, firm base, because the stand sinks into wet soil and tilts.
Frequently Asked Questions About 100 Meter Rain Gun Price in Kenya
How much does a 100 meter rain gun cost in Kenya?
100 meter rain gun price in Kenya run from KSh 4,000 for a 35 metre radius impact gun to about KES 60,000 for the flange model in the shop guide. The 100 metre class sits at the top of that range. The pump is quoted separately.
Does 100 meter mean the throw or the diameter?
It means the wetting diameter. Therefore, a 100 metre gun throws about 50 metres from the stand in every direction, and the circle it covers is roughly 1.9 acres.
How much water does a rain gun use?
The two shop models are listed at 10,000 to 25,000 litres per hour and 8,000 to 50,000 litres per hour. Because of this, the water source must be measured before the gun is chosen.
What pump does a rain gun need?
A gun taking 25 cubic metres per hour at 50 metres of head needs about 6.2 kW at the shaft. That means a 10 HP motor once efficiency is allowed for. A smaller gun at 10 cubic metres per hour needs about 3 HP. This pump requirement is the largest hidden cost behind 100 meter rain gun price in Kenya.
How many acres will one gun cover?
About 1.9 acres for a 100 metre gun and about 0.7 acres for a 35 metre gun, with no wind. In practice, overlap and wind reduce that figure, so plan for more positions.
Can I move a rain gun between fields?
Yes. The 35 metre gun is sold with a tripod stand and is light enough to move by hand. However, a 2 inch gun needs two people and a vehicle for longer moves.
Order a 100 Meter Rain Gun in Kenya
To get a quote, send four figures: the water source yield, the area you intend to irrigate, the pump you already own and the distance from the pump to the field. Those figures decide the gun size, the pipe bore and the price.
The two shop models can be ordered online, and the larger sizes are quoted on request, because 100 meter rain gun price in Kenya depend on the pump that feeds them. Delivery is arranged at the time of order. Also, the rain gun buying guide shows the installation steps for the 40 metre model.
Finally, the pop up sprinkler installation guide is useful if the same pump will also feed a buried lawn line. Both systems draw from one source, so the pump must be sized for the combined flow.
