Gearboxes for single-screw extruders

The ZPE series for single-screw extruders confirms Zambello’s position on the world top level
as to the transmissible torque as referred to weight and dimension of the gearbox.
The series of this range are absolutely complete and go from the smallest gearbox,
of size 90 (for extruders with 25/30 mm screw diameter) up to gearboxes of size 630 (for big extruders
with 300/400 mm screw diameter)

The excellence level of this range concerns the design and the execution of the gears,
manufactured and tested entirely by Zambello, as well as the components, supplied by the major European manufacturers.
Due to the politics of the constant extension of the spare-parts stock,
Zambello is able to ensure the punctuality of the delivery times.
The ZPE range provides 3 different series:
ZPE1 for high speeds (reduction ratio from i=2 to i=5.6)
ZPE2 for medium speeds (reduction ratio from i=6,3 to i=28)
ZPE3  for medium and low speeds (reduction ratio from i=6,3 to i=125).
