How to choose the right agriculture pump?

As one of the most under-rated utilities of all time, the modern-day water pump plays a pivotal role in meeting the requirements of your irrigation needs. Selecting the right irrigation pump for agricultural land will not only result in better crop yield but also help save money and power.

Choosing a poor pump, in turn, results in increased power consumption, poor yield, and poor water supply to the crops. So, here are a few pointers to consider before selecting a pump that is worth investing in.

Before the Pump Selection, let us start with the basics:

Measurement of the land parcel.
Crop’s intensity of water intake.
Frequency of water flow.
Source of water-open well, borewell, pond, drain from the river.
Distance between the source of water and the land.
The Ph level of water.

So, now that you have done the first exercise, let us understand the different types of pumps for agriculture and irrigation that are available in the market.

Borewell Submersible Pumps

These pumps are usually underwater, completely sealed with heavy motors to draw water from large depths and they are largely used for irrigation. These pumps are defined in stages if the water is to be drawn from the borewells. (Watch the case study of CRI pumps drawing water from over 2000 feet with its 113 stage submersible pumps). Borewell Submersible pumps are thin and tall to fit inside the Borewell. The size of the pumps is measured in mm, depending on the size of your bore.

Open well submersible pump

These pumps are again widely used for agriculture and irrigation, but these pumps are used in open wells. These pumps vary from 1 HP to 10 HP in general and are used to draw water for irrigation. Openwell submersible pumps come in vertical and horizontal format.

Centrifugal monoblock pumps

These pumps are again widely used for agriculture and irrigation, but these pumps are used in open wells. These pumps vary from 1 HP to 10 HP in general and are used to draw water for irrigation. Open well submersible pumps come in vertical and horizontal format.

If you require pumps to run for a long duration in a day, these pumps are powered by an enclosed fan-cooled motor. Due to this, the heat resistance will be reduced and the water can be pumped for a long duration.

Compressor pump

If you require water to be extracted from a low-lying area, you require compressor pumps that are usually fitted with a compressor to push water.

Solar pump

Operated with solar energy, these pumps can operate with the lowest power consumption. For solar pumps, though the initial cost may seem high, most governments offer a significant subsidy to promote green energy.

Well, which one to choose now?

The location of the water from where it is drawn plays a crucial role in determining the type of pump. For example, turbine pumps and deep-well submersible pumps are ideally used to draw water from underground like wells, borewells, etc. While there are different types of pumps to help draw water from the surface level.

The pump you purchase must fit perfectly with the rest of the irrigation system. All the specifications listed above must match to maximize cost and energy savings. Choose a pump that helps reduce operational cost, by considering the water pressure and the flow. The right pump helps draw water at the right accuracy and at the right time to help yield better crops, better harvest, and thereby leading to better profitability.

Meanwhile selecting the right pump will ensure better water management, thereby making agriculture a sustainable practice.

Asking the right questions:

1. Is the pump durable?

2. Can this pump run for a long time in a day?

3. Determine the quality of the pump?

a. Installation of these pumps is expensive. So if there are any repairs in the pumps, imagine going through the whole process once again, bringing a jack, lifting the pumps outside the waterbody, carrying them to a mechanic shop, repairing the pumps, and shipping back and reinstallation. Not just the physical pain, but during the peak irrigation times, these could cause severe challenges in the irrigation itself, when your plants will dry of no water.

b. The quality of the pumps plays a major role. Here when we say quality, understand where all the pumps may go wrong usually.

Coil windings: If the pumps get heated up, the coil may burn (Tip: ask if the coil has a protecting guard)
Mud filter: Do the pumps have mud filters and can avoid the clog. (Tip: Only a few specific companies have mud filters.)
Rust formation: What the pump& outer layer coating? (Tip: check for 304 steel or fabricated SS or the outer coating has anti-corrosion treatment done. Also, check for the casting grade)
Co-efficient of friction: Okay, in simple words when the sand falls into the motor, what happens and how to avoid it. This increases the heat and for the failure. (Tip: ask for carbon bush based water pumps)
Coupling portion: Check for the protection and damage history of the brand in the coupling portion. For higher stage pumps the coupling portions have challenges. (Tip: Check for shaft drive-in with 100% SS drive)
Impellers: The fans in common slang. The blades and veins in the impellers need to be in perfect alignment to increase the outcome. (Tip: Check if the impellers are laser welded)

4. What is the warranty offered and after-sales service?

Usually, companies offer 12 months warranty, but in special cases, you may get more.

Before landing on an irrigation pump, choose a pump company that is reliable and highly reputable. Though the branded pumps are a little expensive compared to the local pumps, you can expect the quality to be much better compared to the local players. Imagine the situation of repairing the pump, which shall cost around 25% of the cost of the pump itself, leaving aside the hardships and mental agony of fixing and the loss of the irrigation season.

A durable pump with a technology up-step along with a service backup, will help your irrigation season and empower your agriculture needs. So think smart and pick a quality product that will last longer and support your growth.
