Pump selection plays a vital role in the success of your irrigation and agricultural produce. The right irrigation pump ensures that your water requirements are met and your crops as well as livestock get the best watering efficacy.
Here, in this blog we will give you a step – by-step guide for you to find the right type of pump for your agriculture needs.
Understanding the Basics
Though there are several types of irrigation techniques in practice, the goal is the same – to pump water from the source and to distribute it evenly to your crops . The aim here is to keep the energy requirements low while ensuring that all plants receive adequate amounts of water – neither too low nor too high.
To ensure uniform irrigation of a field, the entire cultivable area is divided into smaller regions called as zones. Zones can be segregated based on soil types, crops cultivated, and irrigation requirements and so on. Each zone is watered with the help of pipes, tubes, sprinklers, and valves, which are connected to a pump.
Step 1 – Choose your Irrigation Equipment
Different equipment requires different amounts of water and pressure and different pumps. Hence, it’s vital that you choose the equipment first before selecting your pump. While choosing irrigation equipment, make sure to consider the controller of the pump .
The controller plays a crucial role in turning off and on water supply at specified periods, or during rains, heavy winds, direct sunlight, etc.
The controller is responsible for water conservation, as it turns off the pump at a pre-set time, so that water seeps adequately into the soil. This reduces runoff.
Step 2 – Consider the Water Source too
The general sources of irrigation water include groundwater from wells, springs or bore wells, surface water from lakes, rivers, reservoirs and other non-conventional sources of water like reclaimed water, drainage water, desalinated water, wastewater and so on. This will determine your choice of pump – centrifugal or submersible!
Step 3 – Determining the Irrigation Pump Type
The location of the water source plays a crucial role in determining the type of pump. Here’s a general guide on what pump works well for different water sources:
* Turbine pumps and deep-well submersible pumps are suitable to draw water from deep underground, think wells, bore-wells, etc.
* When it comes to surface water, you can use several different types of pumps. One advantage of using submersible pumps with groundwater is that the pump is not visible, thereby reducing chances of theft and reduced pump operation noise.
* Two elements necessary to ensure uniform flow of water are – availability of adequate water and the crop’s requirements.
* Instead, of one single large pump, using several small pumps offers various benefits like – reduced aquifer drawdown, decreased energy consumption, easy cut in/cut off pumps based on varying requirements, etc.
Step 4 – Figuring out the Right Size of the pump for your land
Generally, irrigation pump used in irrigation are either over-sized or under-sized. Choosing the correct pump size is essential for the success of your irrigation system.
Some factors to consider while deciding on the pump size are:
* Power consumption
* System pressure
* Variable speed controls
* Motor protection
Step 5 – Remember the System Integration
Today, pumps are no longer stand-alone devices. They have to be integrated with the rest of the irrigation system. This means the pump you choose must match the irrigation equipment perfectly for the best results. All the elements listed above must be integrated to provide the maximum cost savings and best efficiency in fulfilling all your water needs.
An important tip – You can reduce operational costs by ensuring that the water pressure is not higher than required and by using the right controls. Similarly, maintaining the correct water flow and pressure translates to more energy savings.
Apart from expenses, the right pump also ensures better water management, thus making sustainable agricultural practices possible .
