What Are The Different Types Of High-Pressure Pumps For Agricultural Activities

Irrigation is essential in agricultural activities as it ensures plants receive enough water and nutrients. Irrigation systems rely on high-pressure water pumps to get adequate water from a source such as a dam to the farm. They also use pressure pumps and other components like sprinklers, drips, and hoses for additional agricultural applications like dewatering plants, cleaning livestock, and removing sludge and sediments from surfaces. Before buying a pump for agricultural activities, consider its intended purpose and other factors like flow rate, power and water source, total suction, and dynamic head. Below are different high-pressure agricultural pumps and their most suitable application.

Centrifugal Pumps 

These pumps transfer rotational energy from one or more driver rotors called impellers or boosters to the water flow. The impellers increase the water flow rate and pressure to enable enough supply in an entire system. That makes them suitable for agricultural activities that rely on water sources long distances from the farm, e.g., lakes, streams, reservoirs, and shallow ways. The pump maintains consistent pressure and water flow over distant places and prevents crops from drying up. Besides ensuring enough water supply, centrifugal pumps also come with simple, low-cost designs that enhance energy efficiency and user-friendliness. 

Positive Displacement Pumps 

Unlike centrifugal pumps, positive displacement pumps create pressure in the pumping system by changing the available volume or space. It uses pistons, valves, and a closed chamber which decreases pressure in the inlet side that draws water into the pump, thus increasing pressure on the outlets to force (displace) water out. One of the main advantages of using positive displacement pumps is that they can handle fluids with high and low viscosity. That means you can use them for various purposes other than irrigating the field, e.g., high force washing and transporting a slurry of wastes. Other essential benefits include high pressure, high efficiency, and durability.

Submersible Pumps

Submersible pumps are suitable for irrigation activities from a deep water source, e.g., a borehole. The pumps are submersed (lowered into water) and have a hose power cable, enabling pumping water from below the water surfaces. The pump system should be watertight to ensure an adequate flow rate to supply water throughout your farm. Submersion into the water helps avoid cavitation issues when pumps start to form vapor bubbles affecting their operation. Submersible pumps produce less noise and are convenient for agricultural activities in residential areas and places with noise control regulations.  

Conclusion 

Centrifugal, positive displacement, and submersible pumps are just but a broad overview of the many subcategories of high-pressure pumps available for agricultural activities. Before buying a pump, consult a reliable dealer to help you choose the best pump that will meet your needs.
