Herbicide Spray Systems

Precision Weed Control with Oberdorfer Gear Pumps

In modern agriculture, herbicide spraying is a critical process for controlling unwanted vegetation and ensuring healthy crop growth. Many herbicides—especially concentrated or oil-based formulations—are viscous and require specialized pumping systems to ensure accurate and consistent application. Oberdorfer gear pumps are ideally suited for this task due to their positive displacement design, robust construction, and chemical compatibility.

How the System Works

  1. Herbicide Tank: Stores the viscous herbicide solution.
  2. Oberdorfer Gear Pump: Draws the herbicide from the tank and delivers it at a controlled rate to the spray nozzles.
  3. Spray Boom or Nozzles: Distributes the herbicide evenly across the field.
  4. Tractor or Sprayer Integration: The pump can be powered by a PTO shaft, electric motor, or hydraulic drive.

Why Oberdorfer Gear Pumps Are Ideal for Herbicide Spraying

1. Positive Displacement Operation

  • Each revolution of the pump shaft displaces a fixed volume of liquid, making flow rate directly proportional to shaft speed.
  • This ensures precise dosing, even when spraying viscous or thick herbicides.

2. High-Quality Materials

  • Bronze housings and gears: Provide excellent corrosion resistance and compatibility with a wide range of agricultural chemicals.
  • 303 Stainless Steel shafts: Offer strength and durability in harsh environments.
  • Carbon-Graphite Bearings: Selected for wear resistance and long service life, even with abrasive or chemically active fluids.

3. Consistent Performance Under Pressure

  • Gear pumps are relatively unaffected by back pressure in the discharge line, ensuring steady flow even with long hose runs or multiple nozzles.

4. Compact and Field-Ready

  • Easily mounted on tractors, sprayers, or skid units.
  • Operates reliably in dusty, wet, and vibration-prone environments.

Benefits for Farmers and Applicators

  • Effective Weed Control: Ensures uniform herbicide coverage for maximum efficacy.
  • Reduced Chemical Waste: Accurate flow control minimizes over-application.
  • Lower Maintenance Costs: Durable components reduce downtime and servicing.
  • Versatile Integration: Compatible with a wide range of agricultural sprayers and control systems.

Typical Use Cases

  • Row Crop Farming: Spraying between rows of corn, soybeans, or cotton.
  • Orchards and Vineyards: Targeted application around tree bases or vines.
  • Pasture Management: Controlling invasive weeds in grazing areas.
  • No-Till Farming: Applying pre-emergent herbicides without disturbing the soil.
