Parker High Torque Radial Piston Motors - Series MR*, have been designed to perform in demanding environments where consistent torque and efficiency are required. The motors are engineered for high mechanical and volumetric efficiency over a wide range of speed and torque. Due to their special design, the MR motors deliver their maximum performance when the application requires high torque values.

The MR motors are developed in a sturdy design, which ensures durability with resistance to thermal shock and low operational noise. They can be used for both continuous and intermittent duty cycles, allowing high starting torque, which permits small motor sizes without compromising performance. Parker MR* motors are compatible with fire-resistant and biodegradable fluids, broadening their application to more eco-friendly applications.

Parker MR Series is offered in multiple frame sizes and displacements and can have completely different shafts, speed sensors, and connection flanges. With optional accessories, such as gearboxes and parking brakes, it extends the usability of the series. These motors correspond to EN ISO 9001:2008, ISO 14001:2004, and OHSAS 18001:2007, which means that they can be used in the most demanding conditions, including mobile and industrial equipment applications.
