Manual Screen Changer (MSC)

Get More from Your Process

Manual Screen Changers (MSC) are an ideal solution for minimizing labor and downtime for screen changes during routine line shutdown.  The compact design eliminates the need for line disassembly and uses a hand lever or optional ratchet to manually index the slide plate for screen change.  The heart of the Manual Screen Changer is a pressure-activated sealing system.  During screen change when the line is at rest, the slide plate coasts between the relaxed seals.  Once the new screen is indexed online and the line is restarted, the seal system activates to press the seals tightly against the slide plate for reliable leak-free performance. Manual screen changer model sizes accommodate rates to 2,450+ lbs/hr (930+ Kg/h) and can accommodate extruder screw pull-through for feed screws up to 5.5″ (139 mm) diameter.  

PSI Manual Screen Changers can be custom designed for specific applications and processes including higher pressures, integrated divert, and special materials.
