Rain Gun Sprinklers in Kenya
Large-scale commercial farmers find it hard to irrigate crops uniformly and adequately using small sprinklers or drip or rain hose methods. To solve this, our rain guns enhance high-pressure water discharge with a wide coverage that enhances uniform and sufficient irrigation.
They are ideal for tall and high-water requirement crops such as cotton, sugarcane and animal pasture.
Specifications of Rain Gun Sprinklers
- Spray Radius: 25 – 50 meters
- Water Pressure Required: 2.5 to 5 bar
- Discharge Rate: 3,000 – 9,000 liters per hour
- Nozzle Sizes: 12 mm, 14 mm, 16 mm
- Material: Brass, Aluminum or Stainless Steel
- Rotation: Full circle (360°) or part circle (adjustable)
- Mounting Options: Tripod stand.
Advantages of Rain Gun Sprinklers
- Rain guns have a wide coverage and reduce irrigation duration.
- High flow rate thus lowers the irrigation frequency.
- A high radius of flow eliminates the need for a number of sprinklers.
- Uniform irrigation due to high pressure and heavy throws not affected by wind effect.
- Wide range of applications. Works efficiently in maize, pasture, vegetable, fodder and sugarcane irrigation.
Types of Rain Gun Sprinklers in Kenya
Brass Rain Gun Sprinklers
Impact Rain gun Sprinklers made of brass body material.
- Durable and corrosion resistant
- Ideal for long-term commercial use
- Higher upfront cost, lower maintenance
Gear-Driven & Flange Rain Gun Sprinklers

Rain Gun Sprinkler Prices in Kenya
Standard Impact Rain Gun Sprinkler Prices in Kenya:
- 1-inch Rain Gun Sprinkler: KES 8,000 – KES 10,500
- 5-inch Rain Gun Sprinkler: KES 13,000 – KES 17,500.

Rain Gun Sprinkler Prices in Kenya: Factors that affect Cost
- Spray Radius & Flow Rate
Larger coverage (50–80 m radius) means a large rain gun size, thus a higher cost and pump demand.
- Operating Pressure
High-pressure rain guns need stronger pumps, and in that case, high overall system costs.
- Material & Build Quality
Brass models cost more but withstand abrasive water and sun exposure.
- Brand & Availability
Locally stocked models are cheaper than special imports.
How to Choose the Right Rain Gun for Your Farm
Incorrect rain gun sizing leads to heavy water wastage and uneven irrigation. The factors below should be considered when choosing and sizing rain guns.
- Application – Match the rain gun sprinkler to the crop you are irrigating. For crops with high water needs, a larger or flanged rain gun would be appropriate.
- Farm Size – for big farms, large rain guns reduce fittings needed and lower installation cost compared to small sprinklers.
- Pressure needs – Understanding the pressure needs of the rain guns helps when sizing the pump for your impact rain gun. It is also important to account for pressure losses in the system.
- Water Source – assessing the pressure of your water source is important before you settle for a rain gun. This would be essential for deciding whether you buy a booster or a high-pressure water pump.
- Soil type – another important factor is the type of soil in your farm. For poor drainage soils use a low-pressure sprinkler. Sandy soil or highly drained soils may require high-pressure rain guns.
Impact Rain Gun Sprinkler Recommended Pump Sizing Guide
- Determine Required Flow Rate and Head: flow rate and pump head should be within the pump’s designated flow and head range.
- Calculate Total Dynamic Head (TDH): Add Static Lift + Elevation + Friction Loss + Required Pressure Head.
- Select Pump: Choose a pump whose performance curve shows it can deliver your required flow at your calculated TDH. A pump with a minimum 30-35 m head is often needed for basic rain guns.
- Consider Power: Match the rain gun sprinkler system to a pump that provides sufficient power (HP) to move water.
Rain Gun Sprinkler Maintenance Tips
- Install mainline pipe (PVC or HDPE)
- Mount rain gun on tripod or riser
- Connect to pump and test pressure
- Adjust nozzle angle and sector control
Impact Rain Gun vs Drip Irrigation
Rain gun: lower initial cost, higher water use
Drip: high efficiency, higher installation cost
Rain Gun vs Centre Pivot
Rain gun: flexible and portable
Pivot: automated but very expensive
