Constant-throughput backush screen changer with
integrated melt accumulator

The backush screen changers are based on
the sturdy and proven double-piston design.
With just two hydraulic rotary-lift cylinders,
the patented new development offers a mostcompact design. The adjustable backush volume and pressure permits highly effective
screen cleaning and multiplies the number of
cleaning cycles.
An integrated diverter valve enables to discharge the extruder start-up melt. The simple
and robust design, with no additional sealing
elements, ensures a reliable and leakage-free
continuous operation.
