Proportional dosers

Product description

• Dosing range: 0.15 … 5.5%
• Pressure range: 0.3 … 6 bar, depending on the model
• Water flow rate: 5 … 700 l/h
• Dosing feed rate: 0.0075 … 38.5 l/h
• Dosing: proportional, e.g. set to 1 per cent
• Typical dosing tolerance: ± 5 %
• Repeatability: ± 3 % (API675)
• Pressure drop: 0.3 … 1.4 bar

How it works

Connected to the water mains, the dosing unit uses water pressure alone as its driving force. In this way, it draws in the concentrate, doses it to the desired percentage and mixes it with the feed 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 in the event of fluctuations in flow rate or pressure.

Areas of application

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

Areas of application

• Metalworking. The proportional dosing unit is connected directly to the water supply and uses water pressure alone as its driving force. The unit thus dispenses a wide variety of concentrates directly into the reservoirs of traditional or CNC machine tools. Thanks to its precision and reliability, any incorrect dosing is ruled out, thereby preventing errors in the preparation of mixtures (emulsions and solutions).
• The D3IL10 produces a better emulsion thanks to its integrated emulsifying disc (1).
