Why Pressurised Irrigation Needs a Special Pump

Modern farmers now irrigate with RainGun, sprinkler and drip systems instead of flooding the field. These are pressurised systems. A RainGun or sprinkler needs 3–4 kg/cm² at the nozzle for good performance and uniform wetting, and it is the pump that has to deliver that pressure together with high discharge.

Most motors already on farms, and most pumps on the market, are designed for flood irrigation, which needs high discharge at low pressure. On a RainGun line they give poor coverage and uneven wetting.

Why We Build Our Own High Pressure Pumpsets

Our R&D team has spent more than 23 years designing and customising submersible pumpsets for pressurised work in agriculture. Today we offer 100+ pump models, custom designed for 3–10 kg/cm², delivering 600–2,000 LPM and running 2–20 RainGuns at a time.

The same high pressure design serves lift irrigation pipelines of 3–20 km, drip irrigation, household bore wells, high pressure cleaning, and fire fighting with a water jet of up to 120 ft.

Our Milestone: The Mariner on Just 10 HP

We designed and introduced a 10 HP high pressure submersible pumpset that runs the world famous Mariner big RainGun (2.5″, Sime, Italy). Sime recommends more than 20 HP for the Mariner. Our 10 HP runs it with 130 feet radius and 900 LPM discharge. It also runs Skipper and Tublex RainGuns at 120 feet radius, wetting 1.75 acres at a time. It is the only 10 HP motor in India that does this.

Frequently Asked Questions

Why can't I use a standard market pump for raingun irrigation?

Most submersible pumps sold in India are designed for flood irrigation — high discharge at low pressure. Raingun and sprinkler systems need 3–5 kg/cm2 at the nozzle for proper coverage. Standard pumps cannot deliver this, resulting in poor spray radius and uneven wetting. Thumba's pumps are custom-engineered with the right pressure-discharge balance for raingun operation.

Which HP submersible pump do I need for raingun irrigation?

For 1–2 acres with 1.25-inch rainguns, a 5HP or 6HP pump is sufficient. For 3–5 acres with medium rainguns, a 7.5HP pump is recommended. For large farms running Tublex or Mariner big guns, a 10HP pump is required. Thumba provides a free site assessment to recommend the right model for your farm size and water source depth.

Can a 10HP submersible pump run the Mariner big raingun?

Yes — Thumba's 10HP high-pressure pump is the only 10HP motor in India that successfully runs the Mariner (Sime Italy) big raingun. Sime recommends 20HP or above for the Mariner, but Thumba's custom-engineered 10HP delivers 750 LPM at 5 kg/cm2, covering 1.4 acres (140-foot radius) with a single raingun.

What is a multi-stage high head submersible pump?

A multi-stage pump has multiple impeller stages stacked together, each adding pressure. Thumba's 6-stage and 16-stage models generate 10–15 kg/cm2 pressure — suitable for deep bore wells (150–300 feet), long-distance pipelines up to 6 km, and elevated field locations requiring 100+ feet of vertical lift.

How deep can Thumba's submersible pumps work?

Standard open-well models work from depths up to 50 feet. Multi-stage high-head models are designed for bore wells between 150 and 300 feet deep. The 6-stage 6HP suits wells of 40–50 feet, the 6-stage 7.5HP suits 40–60 feet, and the 10/16-stage 10HP suits 150–300 feet.

Can these pumps be used for long-distance water pipelines?

Yes. Thumba's high-head multi-stage models can push water up to 6 km through pipelines at 100 feet of vertical elevation. They are used for lift irrigation projects where water must be brought from a distant canal, river or reservoir to the farm.
