Description
Our proportional dosing pump is a precision-engineered, water-powered fertilizer injection device designed for agricultural irrigation, animal husbandry, and industrial applications. Operating without electricity, this hydraulic dosing pump uses the flow and pressure of water to drive the injection mechanism, delivering a consistent ratio of fertilizer concentrate into the irrigation line regardless of fluctuations in flow rate or pressure. These pumps provide solutions for commercial farms, greenhouses, orchards, and livestock operations, with construction optimized for agricultural environments.
We offer customization to meet specific operational needs: custom flow specifications, special dosing ratios upon request, threaded connection options (BSP/NPT), and alternative materials for specialized applications.

Product Features
The pump is driven entirely by water flow and pressure, requiring no external power source. This design enables operation in remote locations without access to electricity, reduces installation complexity and operating costs, and eliminates electrical safety concerns.
Maintains a preset injection ratio regardless of fluctuations in water flow rate or pressure. Whether the system operates at 25 L/h or 3200 L/h, the pump delivers the selected percentage of fertilizer concentrate, ensuring uniform nutrient application across all crops.
Available in models covering flow ranges from 0.02-5 m³/h up to 0.025-22 m³/h, with dosing percentages from 0.2% to 10%. This selection allows matching the pump to specific application requirements, from small greenhouses to large-scale agricultural operations. The pumps operate across a pressure range of 0.2-8 bar, making them suitable for diverse irrigation systems with varying pressure conditions.
Compact design with threaded connections (3/4", 1", 1-1/2", 2") allows installation into existing irrigation systems. Minimal moving parts reduce maintenance requirements and extend service life.
Product Uses
Our proportional dosing pump serves essential functions across multiple sectors: agricultural crop production for field crops, vegetables, orchards, and vineyards; greenhouse and nursery operations for uniform plant growth; animal husbandry as medicators for livestock watering systems; industrial processes including water treatment and cooling systems; hydroponic nutrient delivery; landscape and turf irrigation for golf courses and sports fields; and remote agricultural installations without electrical service.
Install the pump vertically in a protected location with access for adjustment. Connect inlet and outlet according to the marked flow direction, using PTFE tape on threaded connections. After use, flush the pump with clean water for several minutes to remove residual fertilizer and prevent crystallization. Regular maintenance includes inspecting connections for leaks and cleaning the suction line strainer.
FAQ
The pump uses a water-powered hydraulic motor. Water flow drives a piston or diaphragm mechanism that draws fertilizer concentrate from a container and injects it into the irrigation line in precise proportion to the flow rate.
We offer pumps covering flow ranges from 0.02 m³/h to 22 m³/h, with dosing percentages ranging from 0.2% to 10% depending on the model.
Most models operate from 0.2-8 bar. The 5 m³/h models operate from 1-8 bar. All pumps maintain consistent dosing throughout their specified pressure range.
The pumps are constructed from corrosion-resistant engineering plastics. Alternative materials are available for special applications upon request.
Regular maintenance includes flushing with clean water after each use, cleaning the suction line strainer, and periodic inspection of connections and seals.
