Calzoni

Calzoni High-Torque Radial Piston Motors revolutionize industrial fluid power with their patented Fluid Column Technology. By eliminating traditional connecting rods, piston pads, and pins, Calzoni motors deliver up to 96% starting torque and an outstanding 99% volumetric efficiency directly to the drive shaft. This zero-linkage propulsion system removes intermediate barriers, minimizes energy losses, and eliminates out-of-round cylinder wear caused by lateral forces. Engineered to manage peak pressures up to 420 bar (6,000 psi), these heavy-duty units combine massive power output with exceptionally smooth rotation down to 0.5 rpm
