E-300PRO – The Next Generation of Electric Proportional Dosing

Accurate dosing is essential for efficient fertigation.
In modern agriculture, maintaining precise control over nutrient injection is critical for crop uniformity, resource efficiency, and overall farm performance.
Tefen Flow and Dosing Technologies introduces E-300PRO, an advanced electric proportional dosing pump designed for modern irrigation systems and demanding agricultural environments. Built on decades of expertise in proportional dosing technology, the E-300PRO brings a new level of precision and reliability to fertigation management.

The Challenge in Modern Agriculture

Today’s irrigation systems operate in complex and dynamic conditions. Growers and agronomists must manage nutrient delivery across large areas, varying terrain, and changing hydraulic conditions.

Without accurate dosing, irrigation systems may experience several challenges:

• Fertilizer waste
• Inconsistent nutrient delivery
• Reduced crop uniformity
• Increased operational costs

This is why more irrigation systems are adopting proportional dosing technologies that maintain a consistent nutrient ratio relative to water flow.

The Solution – Proportional Dosing with E-300PRO

The E-300PRO electric dosing pump delivers accurate proportional injection, ensuring fertilizers and nutrients are applied consistently according to water flow.
In Auto Mode, when connected to a water meter and/or fertilizer meter, the pump continuously calculates real-time water flow and automatically adjusts motor speed and injection rate.
This dynamic control allows the system to maintain a stable fertilizer-to-water ratio even when pressure or flow conditions change during irrigation.
The result is improved fertigation accuracy and more reliable nutrient delivery throughout the irrigation cycle.

Built on Decades of Proportional Dosing Expertise

For decades, Tefen Flow and Dosing Technologies has been designing and manufacturing hydraulic proportional dosing pumps used worldwide in agriculture and industry.
This deep engineering experience in flow-based dosing technologies has enabled the development of highly reliable and precise dosing solutions trusted by irrigation professionals.
The E-300PRO continues this legacy, combining Tefen’s proven proportional dosing expertise with modern electric pump technology that delivers:

• Precise proportional dosing based on system flow
• Reliable electric operation for stable performance
• Improved fertigation efficiency
• Designed for modern irrigation systems
• Simple integration into existing fertigation setups

Why Proportional Dosing Matters

The E-300PRO offers a wide dosing range of 0.1%-1%, allowing the system to adapt to different crops, irrigation strategies, and growth stages.

The pump is designed for ease of use and flexible installation. It can operate in both automatic and manual modes, and can be powered by 100-220V AC or 12V DC power, making it suitable for solar installations in remote agricultural locations.

These capabilities make the E-300PRO a practical solution for growers, irrigation system designers, and fertigation professionals seeking reliable and accurate nutrient injection, allowing growers to:

• Maintain consistent nutrient concentration
• Improve crop uniformity
• Reduce fertilizer waste
• Optimize irrigation performance

The E-300PRO is waiting for you

Whether managing a farm, designing irrigation systems, or optimizing fertigation processes, the E-300PRO delivers the precision and reliability required for modern agriculture.

The result is a fertigation system that not only sets the correct dosing ratio but maintains it consistently under real field conditions.
