Dosatron D25RE4 Water Powered Dosing Pumps

The Dosatron D25RE4 Series is a range of water powered dosing pumps designed for accurate proportional injection of liquid concentrates, including fertilisers, nutrients, chemicals, additives and treatment solutions, directly into water systems.

Operating entirely from water pressure, the D25RE4 dosing pumps require no electricity or external power source. As water flows through the unit, the concentrate is automatically injected in proportion to the water flow, maintaining a consistent dosing rate even when system flow conditions change.

With an adjustable dosing range of 0.5–4% (1:200 to 1:25), the D25RE4 is designed for applications requiring medium to higher concentration dosing. With a water flow range of 10–2,500 L/hr, these dosing pumps are suitable for irrigation, fertigation, horticulture, greenhouse systems, livestock applications, water treatment, cleaning processes and general chemical injection applications.

The D25RE4 combines Dosatron’s proven proportional dosing technology with durable construction and easy adjustment, providing an efficient solution where precise concentrate mixing, reliable performance and operation without electrical power are required.
