In agriculture system applications, a submersible pump is a turbine pump close-coupled to a water-tight electric engine, which remove requirement of the lengthy drive shaft and bearing retainers compare to a profound well turbine pump.
The pump is over the motor and water enters the pump through a screen between the pump and motor. Since submersible motors are more modest in width, they are lower proficiency than those utilized for centrifugal or deep-well turbine pumps.
The motor may overheat or wear out if the dissemination of water past the motor is limited or lacking. The length of riser pipe should be sufficient to keep the bowl get together and engine lowered consistently. Likewise, the well packaging should be sufficiently huge to permit water to flow past the motor.
Submersible pumps utilized for water system should have three-phase electrical force and wiring from the pump to the surface should be watertight with all associations fixed.

What is submersible pump?
A submarine siphon is an impenetrable fixed engine close-coupled to the pump body and running under the water. The fundamental benefit of this sort of pump is that an issue related with a high rise (contrast among pump and liquid surface), forestalls pump cavitation and never requires any exertion of preparing as the entire gathering is lowered in the liquid. Submersible pumps burn-through less energy to move water into the pump, the water pressure drives the water into a submersible pump, accordingly “saving” a ton of the pump’s energy.
Type of submersible pump
All irrigation pumps have three main components a motor that drives the pump, an impeller that spins around pushing water from the inlet at the center of the impeller away from it and a diffuser which is a casing around the impeller that collects the moving water and moves it to the outlet. Out of the plethora of pump options listed in a typical pump catalog, there are relatively few that are used in irrigation systems. Before going into specifics let’s take a brief moment to talk about the different kinds of pumps used in irrigation applications.
The kind of submersible pump is openwell submersible pump and borewell submersible pump. In both submersible pumps both the motor and the impeller are placed below the water. The motor spins the impeller or impellers in the diffuser and this forces water up a pipe and into the irrigation system. In order to choose right type of pump you’ll need to know what and where your water source is.
If your water source is well the most common type of pump used is an openwell submersible pump. If the well deeper upto 25 feet you can use open well effectively. For bore well situations a submersible pump is lowered down the pipe and submerged into the water at the bottom of the well where it pushes water to the surface and into the irrigation system. For water source is deeper than 25 feet you will have to use a submersible pump.

Buying guide of submersible pump
There are many parameters to look at before buying submersible pump for agriculture, so that you can choose proper one according to your needs. Read this article to know more “Best Submersible Pump for Borewell”.
Advantage and disadvantage of submersible pump
Advantage:
- Can be used in deep wells
- Priming not needed
- Can be used in crooked wells
- Easy to install in case of open well
- High flow rate
- Reducing chances of theft, in case borewell pump
- Reduced pump operation noise.
Disadvantage:
- More expensive than monoblock and centrifugal pump
- Only electric can be used.
- Difficult to install, in case of bore well
- Maintenance cost is high in case of bore well
- Water movement past motor required.
Pump Sizing for Efficient Irrigation
Selecting and sizing of submersible pump depends on these factors.
- Water source: On based on the water source you can select centrifugal, jet, booster and submersible pump.
- Power: Source of power available 120v or 220v and single or three phase.
- Location of pump: it’s there a place to mount the pump or does the location require a submersible.
- Water quality require filtratio .
- Flow rate: making sure that there is enough flow GPM to feed the largest zone.
- Pressure: making sure that there is enough pressure PSI at the sprinkler at the end of the run.
- Friction loss: -Changes in elevation.
- – Loss through pipe, fittings and valves.
Above all that we’ll need to calculate the two crucial numbers for correctly sizing the pump – the flow rate and the pressure. For the flow rate you’ll need to know the flow rate in GPM of the largest zone in the system or if more than one zone will be running at a time the maximum flow rate that the system will use at any one time.
For the pressure you’ll need to know the pressure that’s needed at the sprinklers to operate the system. For a quick reference in a residential system rotors typically require 50 psi, rotary nozzles sprinklers typically require 40 psi, fixed sprays typically require 30 psi, drip irrigation zones usually require 30 psi as well on high pressure systems a pressure reducer is used to pressure down.
You’ll need to know the friction loss between the locations of the pump and the sprinkler with the greatest pressure loss. This includes things like changes in elevation between the pump and the highest point in the irrigation system and friction loss encountered in pipes fittings and valves.
Finally you’ll need to know about the water pressure or elevation of the water coming into the pump. This can be one of two different things the pressure coming into the system if it is connected to the city water. The height of the pump above the water level of a well or body of water which is called suction lift.
Calculating Flow
Before choosing submersible pump, you should calculate the amount of water to be applied during the peak period by multiplying the amount of water with the size of the field in inches. The result is measured in gallons per minute (gpm).
For example, to grow rice on a 10-acre field using water from a bore well, a pump with highest efficiency at 500 gpm could pump for 24 hours per day. However, by considering for system downtime and power cost windows, a larger pump will always be preferable, and a runtime of the pump between 12 and 18 hours per day.
If the pump’s runtime per day is 12-hour chosen, the pump must be able to pump double the amount—1,048 gpm. Using the curve in Figure 1, the maximum efficiency one submersible pump can provide 1,048 gpm. The calculation for water used by the crop and water loss is:
ETp × Kc = 0.5 × 1 = 0.5 inch per day
Where:
Evapotranspiration potential (ETp) in the area for rice = 0.5 inch per day
Crop efficiency (Kc) = 1
Assume that irrigation efficiency is 80 percent. Now the required amount per day is:
0.5 / 80 × 100 = 0.62 inch per day
With 1 acre inch of water equaling 27,000 gallons, the water needed per acre is:
27,000 × 0.62 inch = 16,740 gallons
A 100-acre field, therefore, requires 1,674000 gallons of water per day, or converted to gallons per minute, the amount required is: 1,674000 / 24 x 60 =1,162 gpm
Calculating Head
An irrigation pump has to overcome the following four elements of pressure:
- Pressure required for the application devices (such as sprinklers, spray heads and drippers)
- Friction loss from the piping system, pipes, screens, valves, elbows and tees
- Elevation lift
- Suction lift
For a deep-well pump, such as a vertical turbine pump or a submersible, another consideration is the drawdown of the static water level. The static water level is defined as the depth to water when no water is being pumped from the well.

Q- Which is the best submersible pump for agriculture in India?
Please read the above article to know about best submersible pump for agriculture.
Q- How to calculate the Efficiency of the Pump?
Calculating the overall efficiency of the pump is a must before selecting any irrigation pump. The electricity consumption depends on how many kW required to run the motor.
This is the simple formula to calculate the efficiency:
Efficiency% = Q * H / 3.67 * P1
Q = water flow measured in m3/h
H = head pressure measured in meters
P1 = the kW of the motor
Point to be noted that your pump must do more than delivering water to the pipes.
Q- Which pump is used for agriculture?
Water is exceptionally fundamental for productive cultivating. Regularly such water is found in different sources like Borewells, Ponds, Wells, Streams, and Rivers. Water pump machine is the best methods for lifting water from these sources. There are various sorts of pump accessible. Picking the right sort of pump relies on the attractions lift and conveyance head.
Centrifugal water pump is most generally utilized for horticulture purposes, it’s anything but a turning machine in which an impeller pivots inside a packaging, attracts the fluid at its middle, and tosses out the fluid through an opening along the edge of the packaging because of outward power.
