Gearboxes for largesingle-screw extruders

The ZPE range of gears by Zambello Riduttori has been enlarged with new torque multipliers. The new devices - named ZPE2 and ZPE3 450, ZPE3 500 and ZPE 560 -  are designed above all for large-size single-screw extruders, feature a case of spheroidal grey cast iron and can be equipped with thrust bearings of different sizes. The new series of multipliers is rounded off with the top-of-the-range ZPE 630 model with electrowelded case and an output torque reaching 450,000 Nm.
