Dosing station, proportional rate 0.1‒7.0 L/h, 60 L

Article : D03656025
  • For dosing of aqueous solutions of chemical reagents  ?
  • Simple and reliable expluatation  ?
  • Adjustable injection rate  ?
VAT NOT included

The Ecosoft proportional dosing station is used for proportional supply of reagents into the line with variable water consumption (e.g. dosing of sodium hypochlorite, sodium sulfite, pH adjusting agents). Proportional dosing is performed upon a signal from a pulse flowmeter.

Key advantages

  • Reliable and easy-to-use

  • Adjustable injection frequency

  • Protection against power surge and peak voltage

  • Chemical resistance of the pump elements to aggressive substances

Components of the station:

  • EMEC FAPVM+ dosing pump with pulse input

  • Foot filter with suction valve

  • Injection valve

  • Set of tubes for connection

  • Level sensor

  • Reagent solution tank

  • Impulse flowmeter

Operation of the dosing station presents accurate supply of small volumes of reagents from the tank into the water flow line with a dosing pump. The dosing pump sucks the solution out of the reagent tank, and delivers its certain volume to the system.

A filter is installed at the suction valve of the dosing pump to prevent sediments from entering the pump resulting in its clogging.

For sound and durable operation of the dosing station it is necessary to control the level of the solution in the reagent tank to prevent an emergency shutdown of the station.

If the reagent is going to be changed (and the pump materials allow that), the dosing station must be washed well with water to remove remains of previous solutions.

It is necessary to add the new portion of the solution to the reagent tank when there is still some solution left in it. The current volume of the solution in the tank should be taken into consideration when calculating the volume of water and reagents.

It is necessary to regularly clean and wash the foot filter installed at the suction valve of the dosing pump.
