With double nozzle designs offering flow rates from 0.47 m³/h to 2.56 m³/h and spray radii from 9.5m to 16.0m depending on pressure, these sprinklers are ideal for vegetable fields, orchards, urban green spaces, and agricultural irrigation systems. Additional models include rotary sprinklers, insect-proof rotating sprinklers, and butterfly-type sprinklers for specialized applications.

Product Advantage

Here are the key advantages of our impact sprinkler series:

• High-Strength Nozzle Construction

Nozzles are manufactured from high-strength engineering plastics or metal materials, ensuring durability and long service life even in demanding agricultural environments. The robust construction withstands continuous operation and exposure to the elements.

• Excellent Hydraulic Performance

Precision-engineered nozzle design delivers exceptional hydraulic performance with stable operation across the working pressure range. The result is high spray uniformity and consistent water distribution across the entire coverage area.

• Fine Droplet Size for Gentle Irrigation

The optimized nozzle geometry produces small droplet diameters with good atomization effect, providing gentle irrigation that minimizes soil compaction and crop damage while maximizing water absorption.

• Double Nozzle Design for Extended Coverage

Most models feature double nozzle configurations (main nozzle + auxiliary nozzle) that increase flow rate and extend spray radius compared to single nozzle designs. This provides greater flexibility in matching sprinkler output to specific application requirements.

• Multiple Configuration Options

Available in various sizes and connection types:

- RS5022 series: 1/2" connection with 2.5-4.0mm main nozzle options

- RS5035 series: 3/4" connection with 4.0-5.0mm main nozzle options

- Rotary sprinklers (SP3302, SP3303) with blue or green nozzles

- Insect-proof rotating sprinklers (IPRS1001, IPRS1002)

- Butterfly-type sprinklers (BMS1001, BMS1002, BMS1003)

• Versatile Application Range

Suitable for vegetable fields, orchards, urban green spaces, and general agricultural irrigation. The wide range of flow rates and spray radii allows matching to specific crop types, field layouts, and water availability.

Product Uses

Our impact sprinklers serve essential functions across multiple agricultural and landscape applications:

• Vegetable Fields

Ideal for overhead irrigation of vegetable crops, providing uniform coverage without soil compaction. The fine droplet size prevents damage to delicate vegetable leaves while ensuring adequate water penetration.

• Orchards

Perfect for under-tree and overhead irrigation in orchards, with models offering spray radii up to 16m to cover mature trees. Suitable for apples, citrus, nuts, and other tree fruits.

• Urban Green Spaces

Excellent for parks, public gardens, and recreational areas where reliable, attractive irrigation is required. The durable construction withstands public use and environmental exposure.

• Nurseries

Suitable for container and field-grown nursery stock, providing gentle, uniform irrigation that promotes healthy plant development.

• Field Crops

Can be used for irrigation of grains, forages, and other field crops where overhead irrigation is preferred.

• Residential Landscaping

Ideal for large residential properties, golf courses, and commercial landscapes requiring professional-grade irrigation performance.

• Frost Protection

Impact sprinklers can be used for frost protection in orchards and vineyards, releasing water that forms ice and releases latent heat to protect sensitive crops.

• Specialty Applications

Insect-proof rotating sprinklers provide controlled, low-angle irrigation for specific applications where minimal water drift is required.

Product Operation Guide

• Installation Steps:

1. Select Correct Sprinkler Model: Choose sprinkler based on:

  - Required flow rate and spray radius

  - Available operating pressure

  - Connection type (1/2" or 3/4" thread)

  - Application (field, orchard, landscape)

2. Nozzle Selection: For RS5022 and RS5035 models, select appropriate nozzle size based on desired flow rate and spray radius. Refer to performance tables for guidance.

3. Riser Installation:

  - Install sprinkler on appropriate riser height for crop being irrigated

  - Use PTFE tape on threads for leak-free seal

  - Ensure sprinkler is plumb (vertical) for proper operation

4. Spacing Considerations:

  - Space sprinklers based on spray radius (typically 50-60% of diameter for overlap)

  - Consider wind conditions and adjust spacing accordingly

  - Refer to irrigation design guidelines for specific recommendations

5. Pressure Regulation:

  - Ensure system pressure is within operating range (0.15-0.4 MPa)

  - Use pressure regulators if necessary to maintain consistent pressure

6. System Check:

  - Pressurize system slowly

  - Check all sprinklers for proper rotation and coverage

  - Verify uniform water distribution

  - Adjust as needed

• Operation:

1. Normal Operation: Impact sprinklers rotate slowly, distributing water in a circular pattern. The double nozzle design provides both near and far coverage for uniform distribution.

2. Pressure Effects:

  - Higher pressure increases flow rate and spray radius (within limits)

  - Lower pressure reduces flow and radius

  - Operate within recommended pressure range for optimal performance

3. Part-Circle Operation (if applicable): Some models can be adjusted for part-circle operation to avoid watering roads, buildings, or non-crop areas.

• Maintenance:

1. Regular Inspection:

  - Check sprinklers for proper rotation during operation

  - Inspect nozzles for wear or damage

  - Verify uniform coverage patterns

  - Check for leaks at connections

2. Nozzle Cleaning:

  - Depressurize system

  - Remove nozzle from sprinkler

  - Rinse with clean water

  - Use soft brush if needed

  - Reinstall and test

3. Seasonal Maintenance:

  - Before winter, drain system completely

  - Remove and store sprinklers if freezing expected

  - Inspect and clean all components before next season

FAQ

Q1: What is an impact sprinkler?

A1: An impact sprinkler (also called a impulse sprinkler or rain gun) uses a spring-loaded arm that strikes the water stream, causing the sprinkler to rotate slowly and distribute water in a circular pattern. They are known for durability, reliability, and long throw distances.

Q2: What is the difference between RS5022 and RS5035 models?

A2: RS5022 has 1/2" connection and lower flow rates (0.47-1.43 m³/h) suitable for smaller areas. RS5035 has 3/4" connection and higher flow rates (1.45-2.56 m³/h) for larger coverage areas.

Q3: What nozzle sizes are available?

A3: RS5022 offers main nozzle sizes from 2.5mm to 4.0mm. RS5035 offers main nozzle sizes from 4.0mm to 5.0mm. All models include a secondary nozzle for extended coverage.

Q4: What is the working pressure range?

A4: Working pressure ranges from 0.15 MPa to 0.4 MPa (1.5-4.0 bar) depending on model. Refer to performance tables for optimal pressure for specific nozzles.

Q5: What are the available flow rates?

A5: Flow rates range from 0.42 m³/h to 2.56 m³/h depending on model, nozzle size, and operating pressure.

Q6: What is the spray radius?

A6: Spray radius ranges from 4.6m to 16.0m depending on model, nozzle size, and operating pressure.

Q7: What materials are used for nozzles?

A7: Nozzles are available in high-strength engineering plastics or metal materials depending on model and application requirements.

Q8: Can these sprinklers be used for frost protection?

A8: Yes, impact sprinklers are commonly used for frost protection in orchards and vineyards. The water released forms ice and releases latent heat to protect crops.

Q9: What is an insect-proof rotating sprinkler?

A9: Insect-proof rotating sprinklers feature a design that prevents insects from entering and nesting in the sprinkler mechanism. They provide small water volume, high uniformity, and water curtain effect – ideal for low-angle applications.

Q10: How do I select the right sprinkler for my application?

A10: Consider your required coverage area, available water flow and pressure, crop type, and field layout. Use the performance tables to match flow rate and spray radius to your specific requirements. Contact our technical team for assistance.
