The Water Line injection pumps expanded since the beginning of 2019 with a new metering pump that can dose chemicals up to 30 m3/h (maximum flow) without electricity.
Chlorine or other disinfection chemicals are in a proportional way dosed and always injected with water at the chosen dosage in order to have an optimum water quality.
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.
The D30WL chemical dosing pump must be assembled in by-pass as shown below.
An in-line assembly is possible but not recommended because it doesn't enable the dosing pump to be easily isolated for maintenance (necessary to cut off the water supply).
For installations from gravity tanks ensure that the minimum water pressure for the metering pump to operate correctly is available.
Installing the D30WL dosing system on a by-pass enables clear water to be supplied to the installation without operating the D30WL chlorine metering pump and enables it to be easily dismantled.
