Covers 60 to 175 feet radius per nozzle. Suitable for farms from 0.5 acres to 50+ acres — for every crop, every pump size, every budget. Manufactured in Palani since 2003.
Get Free Consultation How to Choose ↓A RainGun is a high-pressure rotating sprinkler that throws water in a wide circular arc — just like natural rainfall — covering up to 350 feet in diameter from a single nozzle. Unlike drip irrigation, a RainGun requires no per-plant piping, making it ideal for open-field crops like sugarcane, fodder, groundnut, banana and sports fields.
Thumba's RainGun systems run on 1.5 HP to 40 HP pump sets — single-phase, three-phase, solar or diesel engine-powered. With over 20 years of R&D and manufacturing from Palani, our systems are built for Indian conditions: hard water, irregular power and uneven terrain.
For low-canopy crops (vegetables, coconut nurseries), our micro and impact sprinkler systems give finer droplets, gentler coverage and complete corner-to-corner reach.

Under 1 acre, 1–5 acres or 5+ acres? This decides gun size, pipe length and the number of positions per irrigation cycle.
Browse by Area ↓Tall crops (sugarcane, fodder) need big rainguns. Low canopy (vegetables, coconut) need micro sprinklers for full coverage without damaging plants.
Browse by Crop ↓1.5 HP covers ~2 acres per shift. 5 HP covers 3–5 acres. 10 HP+ covers large farms. Engine and solar options for off-grid areas.
Browse by HP ↓Own land of 2+ acres? Go permanent — less daily labour. Leased land or under 1 acre? Portable economic system keeps investment low.

After multiple failed irrigation attempts by other vendors, a major Assam tea estate approached Thumba. We designed a custom large-scale raingun system for their 500-acre estate — and it has been running successfully ever since.

From small farms in Tamil Nadu to 500-acre estates in Assam — Thumba raingun systems work across India.
A large tea estate in Assam had attempted raingun irrigation multiple times with other vendors — each time the system failed to perform at scale. Thumba's team designed a custom high-pressure system for their 500 acres of tea plantation. The system has been running successfully, documented in full on our YouTube channel.
"Been using Thumba's 5 HP raingun on my 4-acre sugarcane field for 3 seasons. Uniform coverage, no maintenance issues. Water bill dropped significantly compared to flood irrigation."
"Installed Thumba's sprinkler for our 2-acre fodder farm. The micro-climate it creates has improved green fodder yield noticeably. Our dairy herd now has consistent fodder through the dry season."
Yes — if your motor is 1.5 HP or above and the water source is within 20 feet depth, we can connect our raingun system directly to it. Our team checks compatibility before dispatch.
A 1.5 HP raingun covers 65 ft radius (130 ft diameter) — roughly 0.4 acres per position. Shift it 3–4 times per day to irrigate 1.5–2 acres. Larger HP systems cover more per position.
For open-field crops (sugarcane, fodder, groundnut), raingun wins — no per-plant piping, no blockage, no rat damage. For orchards and trellis gardens, drip irrigation is better. We advise based on your specific crop and layout.
Yes. Thumba provides installation guidance, demo and after-sales support. Spare parts, replacement nozzles and pipes are available at our Palani service centre (Mon–Sat, 9 AM–6 PM).
Yes. Our portable 1.5 HP systems can be configured for solar operation, making them ideal for remote farms without grid electricity. Ask our team for solar-compatible pump recommendations.
Our permanent systems are designed for 15–20 years with basic maintenance. HDPE pipes have a 25-year lifespan. Nozzles and fittings may need replacement every 3–5 years depending on water quality.
