Melt pump technology

Melt pump technology

Melt pumps, also called Meltpumps, are used to keep the melt pressure higher and/or constant. In the case of underwater granulation, it can be used to increase the pressure after a co-rotating extruder / compounder. Firstly, you then have enough pressure to granulate and get a nice grain. Secondly, the compounder is relieved and can do what it is for: compound and not have to build up pressure in the last section. Back pressure, material that comes out of the degassing, is thus avoided.

Even with very fine filtration with a melt filter, a melt pump may be necessary to supply the necessary pressure.

Applications where the pressure must be kept constant are, for example, cast film extrusion, ribbons and tapes, but applications where products (3D granulates) that are produced with strand granulation.

If you often change the recipe and/or colour, a melt pump in which the bearing lubrication can be flushed out is a good option.

With regard to the arrangement, there are several options that we would be happy to discuss with you. In the case of underwater granulation, we can integrate the control in the central control. Please contact Plastima for more information.
