Discontinuous hydraulic slide plate screen changer
30 - 7 500 kg/h | FSC Maag Pump Systems

FSC screen changers from Maag Pump Systems are equipped with a pressure-adaptive sealing system as a standard. Thanks to this sealing system, the required sealing forces are adjusted to the actual melt pressure
automatically. Their solid and robust construction, available in all sizes and designs, ensures a reliable and leak-free filtration of molten polymers for many years. This series of screen changer is especially suited for being used in applications with thermally sensitive materials.
On the inlet side, the rheologically optimised flow channel directs the melt flow into the screen cavity, where the breaker plate is located. The molten plastic material flows through the breaker plate which is equipped with screen mesh selected according to the required filtration rate. Downstream of the screen, the cleaned melt stream leaves the filter housing through the flow channel.
The screen supporting plate is moved outside the housing for screen changing, and at the same time, the externally located clean screen is moved to the production position. Depending on the desired drive design, this might be done manually, electrically or hydraulically. Changeover, takes only a fraction of a second, providing continuous operation for applications that are not sensitive to pressure fluctuations.

* Simple operation and uncomplicated screen changing
* High operational reliability
* Short material residence time
* Leak-free mode of operation
* Low pressure consumption
