Certified chlorine dosing pumps for your water treatment

In order to make the water drinkable, the Dosatron ACS or NSF certified metering pumps, installed in line with the water pipe, inject a dose of chlorine (NaClo, CaClo) which allows the destruction of organic matter such as viruses and microbes contained in the water, in proportion to the flow rate.

Since a large part of the chlorine is needed to neutralize these organic materials, the dose of chlorine delivered by the metering pump will allow a part, called free residual chlorine, to remain available to treat possible future contamination of the water in the network or in the homes.

According to the WHO, in drinking water treatment, the free chlorine concentration of the treated water should be 0.2 to 0.5 mg/l.


NSF/ANSI certification - Chlorine dosing pumps

The NSF/ANSI 61 & 372 standard was developed to establish requirements for potential adverse effects on human health of equipment in contact with drinking water (production, transport).

The NSF/ANSI 61 & 372 certified chlorine dosing pumps were subjected to a detailed toxicological analysis. The composition of each device (sub-assemblies, materials, suppliers) was analyzed and referenced by NSF International. Each device has undergone release tests to confirm that harmful particles do not migrate into the water.

The integration of NSF/ANSI 61 & 372 certified chlorine dosing pumps in water treatment applications offers a real alternative to standard dosing technologies, providing precision, robustness and ease of maintenance while protecting the health of users.

ACS certification - Chlorine dosing pumps

Dosatron chlorine dosing pumps certified by the ACS comply with the quality requirements set out in the French Public Health Code (CSP) transposing Directive 98/83/EC of 3 November 1998 on the quality of water intended for human consumption.

The validity of a certificate can be verified by contacting the issuing laboratory, or by consulting the list of valid health certificates of conformity published by the Carso Group laboratories.

label solar impulse for chlorine dosing pumps

All the Dosatron chlorine dosing pumps have received the “Solar Impulse Efficient Solution” Label

One of the first labels for positive impact businesses bringing together protection of the environment and financial viability, the “Solar Impulse Efficient Solution” Label is attributed following an assessment performed by external independent experts. In collaboration with renowned institutions, solutions applying for the label must go through a neutral methodology based on verified standards. This label serves as an award for clean and profitable solutions.

Chlorine dosing pump specification, a well-mastered technology

Installed directly on the water supply line, the certified chlorine dosing pump works with the water in your network as the only source of energy.

The pressure and flow of water drives the engine piston, which is itself connected to a metering piston. Chlorine or other disinfection chemicals are proportionally dosed and continuously injected with water at the chosen dosage. The dose of concentrated product is directly proportional to the volume of water flowing through the dosing pump, regardless of variations in the flow rate and pressure of the water supply to the network.

Self-priming up to 4 meters, our dosing pumps are suitable for degassing products, they guarantee the homogeneity of the dilution. They allow direct reading and easy adjustment of the dosage value.

D30WL chlorine dosing pump operating principle

How our high flow (up to 30m3/h) chlorine dosing pump working ?

The pump technology :
A flow divider in the lower part (patented technology) which ensures a continuous flow division with a constant ratio of the input flow.
A certified chlorine dosing pump in the upper part ensuring the dosing of the desired additive, in proportion to the flow rate supplied by the flow divider. 

As all Dosatron dosing pumps, the dosing of the additive by the system as a whole is proportional to the volume of water, regardless of the variations in pressure and flow rate that may occur.
