Dosatron D45RE8 Water Powered Dosing Pumps

The Dosatron D45RE8 Series is a high-capacity range of water powered dosing pumps designed for accurate proportional injection of liquid concentrates, including fertilisers, nutrients, chemicals and treatment solutions, directly into large water systems.

Operating entirely from water pressure, the D45RE8 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 3–8% (1:33 to 1:12.5), the D45RE8 is designed for applications requiring higher concentration dosing. With a water flow range of 100–4,500 L/hr, these dosing pumps are suitable for large-scale irrigation, fertigation, horticulture, greenhouse systems, water treatment, industrial chemical injection and specialised dosing applications.

The D45RE8 combines Dosatron’s proven proportional dosing technology with high flow capacity and robust construction, providing an efficient solution where accurate concentrate mixing, reliable performance and operation without electrical power are required.
