DMI with P3-System for the dosing
of very small quantities
New pump solves old problem
ALLDOS has launched the DMI P3 system dosing pump for gassing chemicals
such as sodium hypochlorite. This pump is capable of dosing amounts from
0.3 l/h up to 5.2 l/h. In connection with the Etron electronics with stroke
frequency control, it is possible to reduce the dosing flow down to approx.
0.05 l/h whilst retaining accuracy.
Special highlight:
The drawing-in of small dosing quantities, well-known as critical among specialists,
is no longer a problem.
Traditional dosing pumps on a suction lift application with hypochlorite
tend to airlock and hence have an adverse effect on the process.
The new P3 system overcomes this problem by having a priming
chamber built into the dosing head design as an integral working
part. This larger output dosing head continuously draws liquid at
a constant rate into the priming chamber while the smaller front
dosing head can be fed from an integral calibration unit always
under flooded suction conditions. The liquid is then transferred
accurately dosed into the process line. Any overspill as a result
of the lower dosing output from the front head is returned to the
chemical carboy .
With it's high precision, the easy drawing-in and the economical
use of dosing media, the P3 system is the solution for difficult
liquids. The twin-chamber dosing head was especially developed for
highly concentrated, gas-evolving liquids which have to be dosed
in very small quantities and with accuracy
The Plus3 system yet has an additional economical effect: Because there will always be chemical in the priming chamber, it is possible to change the chemical carboy without stopping the dosing pump
Three features avoid unnecessary process interruptions
 |
|
Accurate dosing of very small
capacities with a new double diaphragm system. |
|
|
Reliable dosing
of gassing chemicals with automatic deaeration via a priming
chamber. |
|
|
Precise dosing of concentrated
liquids due to accurate calibration whilst in operation |
|
|
Plus additionally:
Exchanging the containers whilst the pump is running due to constant admission
pressure the priming chamber. |
