How do our D90WL water treatment dosing pumps work?

The only energy source required is the online use of the flow rate, no electricity or additional energy is required. No additional sophisticated equipment, a simple filter upstream and a non-return valve downstream are sufficient. In addition, the water treatment dosing pump is designed to manage the network filling phases and automatically restarts following the overflow of the water supply.

The dosage is adjusted by matching the top of the adjustment ring to the desired scale on the scale. The amount of product injected is proportional to the amount of water entering the dosing pump.

Thanks to its technological innovations, the D90WL water treatment dosing pump is designed to operate with flow rates up to 90m3/h. It is intended to accurately, and proportionally inject chemicals, such as disinfectants, coagulants, and pH adjusters, into water systems. This precise dosing ensures that water is treated effectively to meet quality and safety standards. The technology relies on water flow, eliminating the need for electricity or external power sources, making it versatile and cost-effective.

What is the best way to install my D90WL water treatment dosing pump?

The water treatment dosing pump should be installed in a full hydraulic bypass.

An in-line installation is possible but not recommended because it does not enable the dosing pump to be easily isolated for maintenance (the water supply must be turned off). A by-pass installation enables the system to be supplied with clean mains water when the water treatment dosing pump is not operating and enables it to be easily dismantled.

To prolong your D90WL water treatment dosing pump service life, it should be fitted with an upstream filter (e.g. 200 to 120 mesh – 80 to 130 microns, depending on the quality of your water). This precaution is essential if the water contains impurities or particles, especially if the water comes from a well or if it is surface water.
