Proportional dosers

FLEXIBLE AND WITHOUT NEEDING ELECTRICITY

DOSATRON’s water-driven proportional dosing units work extremely precisely and absolutely reliably without needing to be connected to a power supply. The dosing unit uses only the power of the water flowing through it and calculates the quantity of additives accordingly. The dosage of the prepared stock solution remains constant at all times thanks to the coupled operating principle of the proportional dosing units.

 

PRECISE AND RELIABLE

The way DOSATRON’s water-driven proportional dosing pumps work allows them to be used in a wide range of applications, such as water treatment, food production, dosing of coolants and lubricants, cleaning and disinfection, liquid fertilisation and many more.

DOSATec proportional doser D45

Proportional dosing with external adjustment

Product description

  • Dosing range: 0.03 – 8 %
  • Pressure range: 0.5 – 5 bar, depending on the model
  • Water flow rate: 100 – 4500 l/h
  • Dosing feed rate: 0.033 – 360 l/h
  • Dosing: proportional, e.g. a setting of 1% corresponds to a dosage of 1 :100
  • Average dosage tolerance: ± 10 %
  • Reproducibility: ± 3 % (API675)
  • Pressure loss: 0.2 – 2.3 bar

How it works

When connected to the water mains, the doser uses the water pressure as its driving force, which causes it to draw concentrate in, dose it at the required concentration and mix it with the drive water. The stock solution made in this way flows through the doser. The amount of product dosed is proportional to the water flow rate, even if there are fluctuations in the flow rate or water pressure.

Areas of application

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

DOSATRON | 100 % CONVINCING

Proportional dosing using DOSATRON's dosing pumps opens up even difficult areas of application.


The benefits of this solution are obvious:

  • Water-driven proportional dosing independent of the mains power supply using the driving force of the water flowing through the device.
  • Ideal for mobile use, as it is self-priming (up to 4 metres) and runs without electricity.
  • The dosage is controlled by the water flow via a servo valve.
  • Consistently stable dosing rate and excellent homogeneity of the solution.
  • Environment-friendly operation by avoiding over- or under-dosing.
  • Compact design and rapid deployment thanks to easy adjustment of the dosing rate.
  • Precise and constant dosing of the solution, irrespective of flow rate or pressure fluctuations.
  • Simple installation and maintenance.
