• Pressure range: 0.3 ... 6 bar, depending on model
• Water flow rate: 5 ... 700 l/h
• Dosing feed: 0.0075 ... 38.5 l/h
• Dosing: proportional, e.g. setting to 1 % corresponds to a dosing of 1 : 100

• Repeatability: ± 3 % (API675)
• Pressure loss: 0.3 ... 1.4 bar

Mode of operation

Connected to the water supply, the dosing unit uses only the water pressure as a driving force. In this way, it draws in the concentrate, doses it to the desired percentage and mixes it with the drive water. The working solution produced in this way flows through the dosing unit. The quantity of product to be dosed is proportional to the water flow rate, even if the flow rate or pressure fluctuates.

Fields of application

• Disinfection, cleaning, fertilisation, pest control, lubrication, pH/TH regulation, flocculation, car wash
• Environment, hygiene, water treatment, food industry, car wash, metal processing, printing industry, horticulture

Areas of application

• Metalworking. The proportional dosing unit is connected directly to the water pipe and uses only the water pressure as the driving force. The device therefore doses a wide variety of concentrates directly into the storage tanks of traditional or CNC processing machines. Thanks to its precision and reliability, any incorrect dosing is ruled out, thus avoiding errors in the production of mixtures (emulsions and solutions).
• The D3IL10 produces a better emulsion thanks to the integrated emulsifying disc (1).
