经ACS认证的氯制剂计量泵 - 水流量达8m3/h

为什么使用合格的加药泵很重要?

IIn 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.

由于很大一部分氯制剂需要中和这些有机物,计量泵输送的氯剂量将允许保留一部分,称为自由余氯,以处理未来可能出现的水网或家庭的污染。

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.

ACS认证--氯制剂计量泵

经ACS认证的Dosatron氯制剂计量泵符合法国公共卫生法(CSP)中规定的质量要求,该法沿用了1998年11月3日关于供人饮用的水的质量的第98/83/EC号指令。

证书的有效性可以通过联系发证实验室,或查阅Carso集团实验室公布的有效卫生合格证书清单来验证。


这些计量泵的具体特点是什么?

The D8WL range of chlorine dosing pumps meets dosing requirements for flow rates from 500 to 8,000 l/h (maximum flow).

The D8WL ACS chlorine dosing pumps have also obtained the mandatory French approval (ACS) for all equipment in contact with water intended for human consumption.  See more

These chlorine dosing pumps are characterized by:

  • An optimized design.
  • 按比例计量,无需用电。
  • Proportionality dependent on water flow.
  • Outlet injection.
  • AF seals adapted to alkaline products.

How our certified chlorine dosing pumps working ?

Installed on the water network, our metering pump uses water pressure as its sole driving force. 这样,它吸起浓缩的产品,以所需的百分比计量,然后将其与驱动水混合。

所得溶液然后被送往下游。The dose of product injected is always proportional to the volume of water flowing through our metering pump, regardless of variations in flow rate or network pressure.

See more on how our metering pumps work.


What is the best way to install my D8WL chlorine dosing pump?

In this installation, the injection pump is installed in by-pass in order to facilitate the maintenance of the pump without having to cut off the main water supply.
Be careful in this case the water will not be chlorinated anymore

This configuration also allows, if necessary, and if the main water flow is constant, to carry out a partial by-pass which allows only a part of the flow to go through the metering pump.

Upstream of the chemical dosing pump, on the main pipe, a 60 micron filter is installed to protect the dosing pump motor against impurities. After the filter, it is suggested to install a pressure reducer in order to be sure not to exceed the nominal pressure of the pump.

On the pipe, two taps are made, one before the dosing unit which will be used for the preparation of the mother solution. The other tap downstream of the dispenser can be used for testing the dispenser and/or priming it during start-up, during operation, for taking samples and finally, during maintenance, for rinsing the dispenser.

Finally, a non-return valve is required at the end of the dosing line to prevent water from flowing back into the dosing unit, which could in some cases return to the mother solution and dilute it or even cause the container to overflow.

During the installation, the dosing unit must be at a height higher than the mother solution and ideally not above but on the side.
