Operating Recommendations

• Avoid simultaneous combination of short-term high speed and short-term high pressure.
• Recommended system cleanliness according to ISO code 20/16; nominal filtration 25 µm or better.
• It is recommended to use high-quality mineral-based hydraulic oil HLP (DIN 51524) or HM (ISO 6743/4).
• Minimum recommended oil viscosity: 13 mm2/s (70 SUS) at 50°C.
• Maximum recommended system operating temperature: 82°C.
• To ensure optimal hydraulic motor lifespan, before operating under maximum load, fill the system with fluid and allow the motor to run at moderate load and speed for 10–15 minutes.

The MP 25 C hydraulic motor is suitable for use in special machinery, mobile machines, agricultural equipment, and industrial drives where compactness, reliability, and high rotational speed are important. Thanks to precise tolerances and the possibility of ordering non-standard shafts, this model easily integrates into existing hydraulic systems and ensures stable operation according to the stated parameters.
