Application and Operating Recommendations

The MP 400 CD/4 hydraulic motor is designed for various special machinery and industrial equipment: loaders, manipulators, road and municipal vehicles, stationary drive units, etc. To ensure reliable operation and long service life, follow these recommendations:

• Avoid simultaneous occurrence of short-term high speed and short-term high pressure.
• Recommended working fluid cleanliness according to ISO code 20/16; nominal filtration 25 microns or higher.
• Use high-quality mineral-based hydraulic oils: HLP (DIN 51524) or HM (ISO 6743/4).
• Recommended minimum kinematic viscosity: 13 mm²/s (≈70 SUS) at 50°C.
• Maximum recommended system operating temperature: 82°C.
• Before operating at maximum loads, fill the system with working fluid and allow the hydraulic motor to run at moderate load and speed for 10–15 minutes for break-in.
