CPRM Hydraulic motor

CPRM Hydraulic Motors are spool valve type motors recognized for their compact design, making them ideal for applications with limited space. These motors incorporate an internal check valve, allowing usage without a drain line in certain scenarios. Additionally, they feature a high-pressure shaft seal, with 150 bar as the standard pressure rating.

CPRM Hydraulic Motors offer several advantages:

• Compact Design: Optimized for small spaces.
• Internal Check Valve: Enables operation without a drain line.
• High-Pressure Seal: 150 bar standard, ensuring reliable performance.
• Low Starting Torque: Facilitates smooth start-up.
• High Efficiency: Maximizes power output and minimizes energy consumption.

CPRM Hydraulic Motors come with various output shaft options, each with a specific maximum torque rating:

• C: Ø 25 mm cylindrical with parallel key, max torque: 34 daNm.
• CB: Ø 32 mm cylindrical with parallel key, max torque: 77 daNm.
• Co: Ø 25.4 mm (1") cylindrical with parallel key, max torque: 34 daNm.
• SH: Splined (SAE 6B), max torque: 40 daNm.
• SB: Ø 31.75 mm splined, max torque: 77 daNm.
• S: Ø 31.75 (1 ¼“) splined, max torque: 77 daNm.
• k: Conical 1:10 with parallel key, max torque: 40 daNm.

Note: Additional shaft options (*C1, *ka) are available upon request.

CPRM motors offer flexibility in mounting with various flange options:

• Oval Flange (2-hole): SAE A standard.
• Magneto Flange (4-hole): Designed for magneto mounting.
• Square Flange (4-bolt): Provides a secure and versatile mounting solution.

Selecting the appropriate motor involves considering factors like:

• Required speed and torque: Determine the operating speed and torque demands of your application.
• Load characteristics: Assess the type and magnitude of loads the motor will encounter.
• Duty cycle: Consider the duration and frequency of motor operation.
• Environmental conditions: Factor in temperature, humidity, and potential exposure to contaminants.
• Space constraints: Ensure the motor's dimensions fit within the available space.

Refer to the provided performance data tables and application calculation guidelines for assistance.

Implementing oil drainage from the motor's drainage space offers several benefits:

• Cleaning: Removes contaminants from the motor, promoting longevity.
• Cooling: Dissipates heat, preventing overheating and potential damage.
• Seal Lifetime Prolonging: Reduces wear and tear on seals, extending their service life.

The standard rotation for CPRM motors is clockwise when port "A" is pressurized. Conversely, pressurizing port "B" results in counter-clockwise rotation. You can customize the rotation direction during the ordering process.

The maximum return pressure varies depending on whether a drain line is used:

• Without Drain Line: The return pressure is limited to the maximum pressure specified for the drain line.
• With Drain Line: The return pressure should not exceed the maximum value indicated in the technical specifications.
