The Wilger Manifold System: A Cornerstone of Precision Liquid Application
At AgXcel, precision is more than just a goal—it’s a commitment. One of the key components that supports this mission is the Wilger manifold system, a highly adaptable and field-tested solution for managing and monitoring liquid flow in agricultural applications. Whether you’re applying liquid fertilizer in-furrow, mid-row, or through side-dress systems, the Wilger manifold plays a vital role in ensuring every drop is delivered exactly where it’s needed, at the correct rate, and with minimal effort.
Why the Wilger Manifold System Matters
The Wilger manifold system is known for its modular design, chemical resistance, and ease of maintenance. But what truly sets it apart is how it empowers growers to visually monitor and precisely regulate the flow of liquid fertilizers, micronutrients, and other ag chemicals across multiple rows.
When used in AgXcel’s proprietary systems—such as the GX1 Low Volume In-Furrow Pump Solution or the GX2 Dual-Pump Fertilizer System—the Wilger manifold becomes more than just a component. It becomes a central part of a broader solution that combines pump control, real-time monitoring, and flexible application.
Floating-Ball vs. O-Ring Seal (ORS) Manifolds: Two Reliable Choices
AgXcel offers multiple Wilger manifold options to suit a range of farming needs. Two of the most commonly used types are the Floating-Ball Flow Indicator Manifold and the O-Ring Seal (ORS) Manifold System.
Floating-Ball Flow Indicator Manifold
This is the most recognizable Wilger manifold setup, and for good reason. It uses transparent flow columns containing floating colored balls that provide instant visual confirmation that product is moving through each row. As fluid flows up through the column, the ball rises—making it immediately clear whether product is flowing and how much.
Key Features:
• Mounted on a laser-cut powder-coated bracket for durability and easy mounting.
• Includes 1-4 lb. check valves with integrated orifice cavities for accurate metering and backflow prevention.
• Comes with multiple orifice sizes to adjust flow rate depending on application needs.
• Swivel-mounted bracket allows for 90° of rotation to improve visibility from the cab or field side.
• Each assembly is pre-assembled and tested by AgXcel to ensure plug-and-play functionality.
Growers love this system for its clarity and reliability, especially during high-speed planting where monitoring flow at a glance is essential.
O-Ring Seal (ORS) Manifold System
The ORS system is built for scalability and customization. It features a modular block design with ported connections that use heavy-duty O-rings to maintain a leak-free seal even under variable pressure. This system is ideal for setups where flexibility, expandability, and chemical compatibility are critical.
Key Features:
• Made from glass-reinforced polypropylene, offering excellent chemical resistance.
• Configurations available from 1 to 4+ outlets, allowing growers to adapt based on implement size and flow needs.
• Each port can be equipped with a Wilger metering orifice, check valve, or both.
• O-rings made of Buna-N or Viton, depending on chemical compatibility.
• Tool-less design allows quick replacement or reconfiguration of ports and fittings.
• Optional integration with Wilger Combo-Rate electronic flow monitoring for data-driven application.
This option is especially popular for growers who are running more complex equipment setups or who want to scale their system as needs change.
AgXcel + Wilger: A Powerful Partnership
AgXcel integrates Wilger manifold systems into many of its most popular product offerings. For example:
• The GX1 Low Volume In-Furrow System includes a fully pre-assembled Wilger floating-ball manifold mounted to a swivel bracket, complete with check valves, filters, and spare orifices.
• The GX2 Dual-Pump System includes two independent Wilger manifolds, ideal for split applications where growers want to apply two different products simultaneously but at different rates.
• For more advanced needs, such as those in variable rate systems (GX30) or mid-row side dress applications, growers can opt for an ORS manifold setup with digital flow sensors and ISOBUS-compatible controllers.
All AgXcel systems featuring Wilger manifolds are tested in-house to ensure precise flow calibration. Each kit includes detailed instructions, spare parts, and mounting hardware for easy field installation.
Wilger Flow Monitoring: Visual and Electronic
AgXcel’s systems benefit from the best of both worlds—visual flow monitoring and electronic precision.
• Visual monitoring is made possible by Wilger’s floating-ball columns, which are color-coded based on flow rate (ranging from 0.01 to 2.7 GPM), giving the grower a quick diagnostic view of every row.
• For growers looking to integrate their data into a controller or virtual terminal, Wilger’s Combo-Rate electronic flowmeter system can be added to send digital feedback about flow consistency, underperformance, or failure in real time.
This dual-monitoring approach means that even in low-light or high-dust conditions, operators can trust their system is working correctly—and if not, they’ll know immediately.
Precision Backed by Simplicity
What makes the Wilger manifold system so effective in AgXcel’s lineup is its balance of complexity and usability. These aren’t over-engineered parts requiring constant attention. Instead, they are designed for:
• Quick setup
• Minimal maintenance
• Maximum reliability
• Long service life
And with AgXcel’s pre-assembled kits, everything arrives ready to mount, connect, and go.
