About diesel irrigation pump

Types of Diesel Irrigation Pump

The diesel irrigation pump is one of the most popular pumps for farmers. As people say, agriculture is the backbone of the economy, and water is considered the blood of agriculture as it nourishes the plants. With water being this important, irrigation pumps come in handy to help in the supply of water to the crops. A pump is a mechanical device that moves fluids or semi-solids by using a vacuum, which is mainly used in the field of irrigation.

Irrigation pumps have existed since ancient times. Earlier, irrigation practices were done by utilizing what nature offered, such as rivers and rain. However, modern irrigation systems enable farmers to deliver water to crops consistently, improving crop health and quality. Different types of irrigation pumps help the farmers deliver water appropriately, and they include the following.

Self-Priming Centrifugal Diesel Pump

Self-priming centrifugal diesel pumps can be used in different types of irrigation, like surface flood and furrow irrigation. These pumps can be self-priming, making them different from normal centrifugal pumps. This means they can remove air from their casing when initially filled with water, allowing them to be used without having to prime them constantly. They are often used for transferring large quantities of liquid with moderate viscosity. They also have a larger variety of impeller designs, which helps in pumping different types of irrigant solids.

Vortex Diesel Pump

Vortex diesel pumps are mainly used when the irrigation fluid contains a lot of solids, as their impeller helps minimize damage caused by the solids. The resulting flow that comes out from the vortex pumps is less contact from the impeller to the solids resulting in slower disintegration. This makes them suitable for irrigation areas that have effluent or irrigation fluid that is not clean. Vortex pumps are not commonly used, but when needed, they help in adequately irrigating the land.

Submersible Diesel Pump

Submersible water pumps for farms are used for different irrigation methods, including localized, surface, and flood irrigation, which can help lessen the water wastage that goes on. They are designed to be submerged in water to collect the water and push it to the surface. This makes them ideal for drawing water from deep wells, boreholes, and reservoirs. Submersible pumps are horsepower efficient and less noisy, making them an ideal water source for remote areas of the farm.

End Suction Pump

End-suction diesel pumps are used for different irrigation types, like sprinkler irrigation. These pumps are commonly used to reduce solids that have been suspended. They are the most common centrifugal pumps, with the water entering axially and exiting radially from the pump's volute. They are used in different applications, such as irrigation, where they deliver high volume flow rates against medium to high-pressure requirements.

Industrial Applications of Diesel Irrigation Pump

Diesel irrigation pumps are not only used for agricultural irrigation but also provide various industrial services.

Irrigation of Agricultural Lands

Diesel irrigation pumps are used in industrial agriculture for irrigating large areas of farmland. With strong builds, they can handle a variety of water sources, such as rivers, wells, or reservoirs, and provide a consistent water supply to crops, ensuring optimal growth even in dry seasons.

Mining Operations

Mining operations, especially those in remote areas without access to electricity, rely on diesel irrigation pumps for dewatering and irrigating vegetation in areas that have been cleared. These pumps are used to help control water in the mining pits, which allows mining to continue and minimizes flooding. Also, the water that has been extracted through irrigation can be used for dust suppression and mineral processing.

Construction Projects

Diesel irrigation pumps are used on construction sites for concrete mixing, dust control, and irrigation of the site vegetation. They are used to dewater excavations and keep the working areas dry. Also, the water is used to keep the soil stable and an ideal working area for the constructors.

Emergency and Fire Fighting

Diesel irrigation pumps are used in emergencies, such as flooding and firefighting. In firefighting, they irrigate large areas quickly, helping mitigate fires in forests, brush, and rural areas. During floods, they can be used to remove excess water from flooded regions, temporarily alleviating water and helping protect properties and infrastructure.

Industrial Cooling Systems

In industrial settings, diesel irrigation pumps are used for cooling system water circulation in power plants and factories. These pumps help maintain the required temperature levels by moving large volumes of water for heat dissipation, thus ensuring the smooth operation of machinery and equipment without overheating.

Water Transfer

Diesel irrigation pumps are used to transfer water between different sources, like moving water from a reservoir to irrigation fields or from one mine site to another. They can also be used to provide emergency irrigation water to areas that have been affected by drought.

Product Specifications and Features of Diesel Irrigation Pump

Technical Specifications

  • Engine Specification: Most diesel pumps come with reliable diesel engines that deliver plenty of power to handle large volumes of irrigant. The engine's horsepower usually ranges from 5 to about 500, depending on the pump's size and irrigation needs.
  • Maximum Head: The maximum head is the highest point the pump can raise water, usually measured in feet or meters. Diesel pumps can handle a lot, with some going up to 485 feet (around 148 meters) or more. This makes them suitable even for deep wells or elevated fields.
  • Flow Rate: Flow rate measures how much water the pump can move in a certain period, often expressed in gallons per minute (GPM) or cubic meters per hour (CMH). Many diesel pumps pump thousands of GPM, making them helpful over large areas.
  • Fuel Tank Capacity: Fuel tank capacity determines how long the pump can run before needing a refuel. Larger diesel pumps can hold more than 50 gallons (about 189 liters) of fuel, giving them long operation for big irrigation tasks.
  • Outlet Diameter: Outlet diameter states how large the water exits the pump, commonly ranging from 2 to 6 inches. Bigger diameters mean more water moves out, which is good for large fields.
  • Wet Steam: Wet steam is the recommended max temperature for the water entering the pump, often in degrees Fahrenheit or Celsius. Many irrigation pumps handle up to 80°F (27°C) without issues.

How to Install

  • Installing the Pump: The installation of the pump depends on the type of pump the user is using. Centrifugal pumps should be installed close to the water source, while submersible pumps should be inserted into the water source.
  • Connecting the Engine: The diesel engine should be connected to the pump shaft using couplings.
  • Fuel System: The fuel system should be installed depending on the manufacturer's manual to avoid incidences.
  • Water Intake: The water intake hose should be connected to the pump and placed into the water source to prevent movement.
  • Outlet Pipe: The irrigation area should be connected to the outlet pipe to prepare for the pump.
  • Starting Up: The engine should be started to ascertain that the diesel pump is working perfectly; water should come out from the irrigation area.

Maintenance and Repair

  • Engine Maintenance: The engine should be checked always by ensuring that the diesel level is at an optimum level. The oil and filters should also be changed regularly for effective functioning.
  • Water Source and Irrigant Check: The water source or irrigant should be checked to see if there are any foreign materials that can affect the pump or crops.
