The Gearboxes are designed for connecting gear pumps to farm tractor power take offs (PTO). Output speed of power take offs is 540rpm which can be compared with the proper running speeds of hydraulic pumps. Different input running speeds can also be suitable,provided that the gearbox output speed does not exceed 3000 rpm.

Shafts
Made in steel UNI 16 CRN4.They are coupled with gears via splined parts and are thus more suitable to stand the torques stated in the catalogue.
Pump assembly
