Gear pumps for agricultural machines

Gear pumps are positive displacement pumps that are commonly used in various industrial applications to transfer fluids. Their efficiency, reliability, and precise fluid delivery are why gear pumps are trusted for varied applications. Primarily two metallic interlocking gears housed within a casing make up the working of gear pumps. When power is supplied to the gear pumps the interlocking gears rotate in opposite directions in process creating vacuum chambers between the gear teeth and the casing allowing the fluid to enter and exit the pump.

The gear pump works when the fluid is sucked into the vacuum created by the separating gears while rotating. The fluid is then carried off to the discharge port as the previously vacuum portion of the gear seals the fluid between the gear and the casing. As the gears are made of with precision, they do not allow any backflow and the continued meshing makes sure the fluid is pushed towards the outlet. This displacement mechanism ensures a steady flow of fluid with minimal pulsation.

Gear pumps offer several advantages over other types of pumps:

Efficiency
High volumetric efficiency is the strongest calling card of gear pumps. Regardless of the pressure variations the delivery of flow rate is constant. With no backflow, the positive displacement design ensures a constant output.
Compact Size
Gear pumps are relatively smaller than other pumps which allows for installation in machines where space is limited or customers are going for compact design. This also makes it easier for gear pumps to be integrated into existing sytems.
Self-Priming
Self-priming is possible in gear pump, which means fluid cab be drawn into the pump without additional external priming mechanisms.
Wide Range of Fluid Compatibility
Whether it is abrasive materials or viscous fluid, gear pumps can handle wide variety of liquids. Due to the variety offered, industry limitation for gear pumps is not particularly high.
Reliable Operation
With minimalistic design, few moving parts and robust build quality, gear pumps offer reliable operation. Even servicing and maintaining the pump is easier which allows for little down time and overall efficiency of the machine.

Despite their numerous advantages, gear pumps also have some limitations

Limited Pressure Capability
The pressure range for gear pump is limited and high-pressure utilization is not always possible. It is possible to manufacture gear pumps for use in high-pressure environment but those pumps are noisy and they require continued surveillance.
Susceptible to Damage from Contaminants
Solid particles in fluids being pumped can wear on the gears of the pump and can damage the overall displacement of the pump.
Noise and Vibration:
Gear pumps are relatively on the noisier side. This can be mitigated to an extent with material and design but noise can still be substantial and grating over longer periods of use.
Limited Speed Range
Speed is one of the biggest limiting factors for gear pumps as the precision of the gears and the tolerances within the casing limit the speeds the pump can be used at. High speed means faster wearing of the gears.

Despite the limitations, there are more and more industries that employ gear pumps in their machine for their pumping needs. One such industry that relies heavily on pumping fluids, lubricants and power transmissions is agricultural industry. The precision offered by gear pumps as well as the reliability makes them ideal for use in agricultural machinery. Some of the agricultural machinery that use gear pumps are listed below;

Tractors
In tractors gear pumps are employed to power hydraulic systems responsible for operating implements, such as front loaders, backhoes, and hydraulic cylinders. The pumps provide the necessary hydraulic pressure which in turn controls the implements, ensuring efficient operation.
Sprayers
Whether mounted or boom attached, sprayers use gear pumps to provide precise and consistent fluid delivery. Gears pumps constant flow supplies the spray nozzles with the required volume and pressure, ensuring even distribution of the chemicals over the fields.
Harvesters
Harvesters, including combine harvesters and forage harvesters, rely on gear pumps to power hydraulic systems that control the movement of cutting blades, conveyors, and other components. They also facilitate the lubrication of critical parts.
Irrigation Systems
Similar to sprayers, gear pumps ensure the transport of water from source to irrigation fields. The gear pumps utilize the even flow and pressure to distribute water equally through the system and ensure there is no over or underwatering of crops.
Seeders
Seeders, as the name suggest are agricultural machines that optimize the seeding process of a field. Gear pumps are used in seeders to provide hydraulic units with power which in turn allows for precise and consistent placement of the seeds. Depth control, seed delivery, even primary watering can be controlled with the help of gear pumps.
Fertilizer Spreaders
Unlike seeders, there is not precision to fertilizer spreader. Still, gear pumps are used to power the hydraulic system that either powers the conveyer or the roller system as well as movable floors in some machines to spread fertilizers over the field being cultivated.
Feed Mixers
In feed mixing machines, gear pumps power the hydraulic system which allows the transport, mixing and delivery of the feed mix used in animal husbandry. The pumps powering the hydraulic system ensures consistent mixture and even distribution of the nutrients for healthy feeding of the animals.
