Available in an extremely wide displacement range, 33cc-23033cc, and pressure rated to 3,600psi continuous and 4350psi intermittent, the patented rotary motion design is achieved by use of a rotary valve and telescoping cylinder (piston) movement. The shaft contains an eccentric lobe and is rotated by a pressurized column of oil contained within telescoping cylinders. The cylinders seal against the eccentric lobe and actually push the shaft as they pressurize and extend. The rotary valve is a precise timing system that is pressure balanced and self compensating for thermal expansion. Coupled together, the rotary valve and telescoping cylinders produce a motor with extremely high mechanical and volumetric efficiency. Other features and benefits of the MR series include:

  • output torque is consistently smooth, even at low speeds;
  • high starting torque;
  • high volumetric efficiency;
  • high mechanical efficiency;
  • long service life;
  • resistant to thermal shock;
  • solenoid operated displacement regulator (dual displacement).

The full MR range comprises:

  • MR-MRE Series: LSHT small displacement radial piston motors, 33cc/rev – 8,200cc/rev fixed displacement;
  • MRD Series: LSHT dual displacement radial piston motors MR, MRDE: 300cc/rev – 8,200cc/rev; dual displacement;
  • MRV Series – LSHT variable displacement radial piston motors MRV, MRVE: 450cc/rev – 8,200cc/rev; variable displacement;
  • MRT Series: LSHT large displacement radial piston motors, MRT, MRTE, MRTF: 7,100cc/rev – 23,033cc/rev; fixed displacement.

Calzoni radial piston motors can also be directly interchanged with Italgroup radial piston motors – visit our Italgroup pages to find out more.
