Dosatron D45REIE3 Water Powered Dosing Pumps

The Dosatron D45REIE3 Series is a high-capacity range of water powered dosing pumps designed for accurate proportional injection of liquid concentrates, including chemicals, fertilisers, nutrients and treatment solutions, directly into large water systems.

Operating entirely from water pressure, the D45REIE3 dosing pumps require no electricity or external power source. As water passes through the unit, the concentrate is automatically injected in proportion to the water flow, ensuring precise and consistent dosing even when system flow conditions change.

With an adjustable dosing range of 0.5–3% (1:200 to 1:33), the D45REIE3 is designed for medium concentration dosing applications requiring reliable proportional injection. With a water flow range of 100–4,500 L/hr, these dosing pumps are suitable for irrigation, fertigation, horticulture, greenhouse systems, water treatment, industrial chemical injection and specialised dosing applications.

The D45REIE3 combines Dosatron’s proven proportional dosing technology with external injection capability and robust construction, providing an efficient solution where accurate concentrate mixing, chemical compatibility and operation without electrical power are required.
