Parker Calzoni MRD300D150N1NININ1N Radial Piston Hydraulic Motor
I. Product Overview
The Parker Calzoni MRD300D150N1NININ1N is a low-speed high-torque dual-displacement radial piston hydraulic motor from the Parker Calzoni MRD series. This motor features patented Fluid Column Technology and Balanced Forces Concept design, transmitting force directly to the output shaft through a pressurized oil column without traditional mechanical components such as connecting rods, piston slippers, etc. The simple structure delivers up to 96% efficiency and exceptional reliability.
The MRD series features dual-displacement design, allowing switching between two displacements via control valves to meet torque and speed requirements under different operating conditions. The motor adopts a 5-piston radial arrangement with flange mounting, suitable for heavy-duty transmission applications such as construction machinery, marine propulsion, mining equipment, oil drilling rigs, injection molding machines, winches, and more. The operating temperature range is -30°C to +80°C, adapting to harsh industrial environments.

VII. FAQ
Q1: What type of hydraulic motor is the MRD300D150N1NININ1N?
A: This model is a Parker Calzoni MRD series low-speed high-torque dual-displacement radial piston hydraulic motor, featuring patented Fluid Column Technology, with 304 cm³/rev displacement, suitable for heavy-duty transmission applications.
Q2: What does dual-displacement mean?
A: Dual-displacement design means the motor can switch between two different displacements (ratio 1:2). At smaller displacement, speed is higher and torque is lower; at larger displacement, speed is lower and torque is higher. Switching is controlled via valves based on operating conditions.
Q3: What are the max operating pressure and speed of this motor?
A: Max continuous operating pressure is 250 bar, max intermittent operating pressure is 300 bar, max speed is 300 rpm, and max power is 420 kW.
Q4: Can you provide detailed selection manuals and performance curves?
A: Yes. Please contact via email with your requirements, and we will provide detailed technical manuals, performance curves, and selection support.
