Dosatron® D45RE15 Injector

Product Overview

System shutdowns during the height of the growing season can lead to immediate crop loss and catastrophic turf damage. When your fertigation system fails, your clients face dead landscapes and missed harvest windows. With peak demand placing immense pressure on irrigation infrastructure, waiting for replacement parts is not a viable strategy. Supply chain fluctuations often result in long lead times for specialized injection equipment. Investing in high performance units now ensures you avoid the risk of back-orders while keeping your projects on a strict timeline and your clients' operations running without interruption.

The Dosatron D45RE15 offers a distinct technical advantage by operating entirely on water pressure without the need for electricity. This eliminates the labor costs and complexities associated with wiring or external power sources at remote sites. Unlike low grade venture injectors that suffer from inconsistent dosing during pressure fluctuations, this volumetric design maintains a precise ratio regardless of flow rate changes. By stocking these units, you provide your crews with a reliable solution that reduces long term maintenance callbacks and gives your business a competitive edge in professional chemical delivery.

Product Specifications

Available Models & Sizes

The D45 series is available in several configurations including various seal materials such as Viton or EPDM to accommodate specific chemical compatibilities. While this 20 GPM unit handles most mid-range commercial applications, please contact our sales team for full configurations, high-flow industrial models, or bulk pricing for large scale projects.

Key Features

• Piston driven motor ensures consistent chemical delivery even in remote areas without electrical access.
• Integrated adjustment sleeve allows your crews to dial in precise dilution rates with ease.
• Superior chemical resistance provided by high density plastic components designed for harsh fertilizers.
• Internal bypass capability protects the motor from damage during high pressure surges or non-injection periods.
• Simplified maintenance design allows for tool-free seal replacement and routine cleaning in the field.
• Compatible with standard 1 inch plumbing systems for seamless integration into existing fertigation manifolds.

Common Applications

• Commercial landscape irrigation for large scale turf management.
• Agricultural and crop irrigation for precise nutrient delivery.
• Greenhouse and nursery operations requiring accurate pesticide application.
• Sports turf and golf course maintenance for consistent fertilization.
• Municipal parks and public spaces where electrical access is limited.
• Chemical and fertigation delivery for hydroponic growing environments.

Installation Notes

Installation should include a 200 mesh or finer pre-filter to protect the internal piston from sand and debris. Secure the unit to a stable vertical surface using the included wall bracket and ensure flow direction follows the indicated arrow. It is standard practice to install a three-valve bypass manifold to allow for system servicing without shutting down the main water line. Always consult local backflow prevention codes to ensure your installation meets municipal requirements for chemical injection systems.
