In the thermal separation process, a concentrate pump is used in addition to the feed pump. The gear pump at the bottom of the column enables the gentle and uniform discharge of the concentrated medium.
The design, materials and pump size are based on the properties of the feed medium, in particular the changes generated by the column in terms of viscosity and rheological behavior of the fluid.
If required by the process, a large pump inlet flange and optimized inlet geometry provide cavitation-free discharge even of highly viscous, viscous fluids.
Hydraulic heating by means of heat transfer oil allows not only the pump head to be heated, but also the discharged fluid.
The shaft seal is vacuum-sealed and designed in accordance with the TA Luft (German Clean Air Act). For example,buffered mechanical seals or combinations of threaded shaft seals and double, buffered stuffing boxes are used.
What are the special features of the concentrate pump?
The heating channels in the pump housing, which are arranged close to the friction bearings and gearwheels, and the heating channels in the pump covers ensure a uniform pump and media temperature. This ensures uniform temperature control and thermally gentle discharge of the sump product from the column.
Different combinations of seals are also available for different applications. For example, vacuum-tight shaft seals in the form of double-acting mechanical seals or threaded shaft seals in combination with stuffing boxes can be used.
