Operating Recommendations

• Short-term high speed and short-term high pressure should not occur simultaneously
• Recommended filtration: ISO 20/16 cleanliness code; nominal filtration 25 microns or higher
• Use of high-quality mineral-based hydraulic oil HLP (DIN 51524) or HM (ISO 6743/4) is recommended
• Recommended minimum oil viscosity: 13 mm²/s [70 SUS] at 50°C [122°F]
• Recommended maximum system operating temperature: 82°C [180°F]
• To ensure optimal hydraulic motor life, fill with working fluid and allow the motor to operate under moderate load and speed for 10–15 minutes before maximum load

The MR 200 C hydraulic motor from M+S Hydraulic under the Hydro-pack brand is a reliable solution for equipment requiring high efficiency at moderate speeds and stable operation under loads. Thanks to the option to choose shaft, flange, and port variants, this motor easily integrates into existing hydraulic systems and provides a long service life when filtration and lubrication recommendations are followed.
