Operating Recommendations

• Do not allow simultaneous operation at intermittent speed and intermittent pressure.
• Recommended filtration: ISO cleanliness code 20/16; nominal filtration 25 µm or higher.
• It is recommended to use high-quality mineral-based hydraulic oils HLP (DIN 51524) or HM (ISO 6743/4).
• Minimum recommended oil viscosity: 13 mm²/s (70 SUS) at 50°C.
• Recommended maximum system operating temperature: 82°C.
• Before prolonged operation under maximum load, fill the system with working fluid and allow the hydraulic motor to operate at moderate load and speed for 10–15 minutes for optimal component break-in and extended service life.

The MP 400 C gerotor hydraulic motor combines compact dimensions with the ability to operate at moderate pressures in continuous mode or under short-term peak loads. Thanks to the availability of shaft options and standard seals, this unit is easily integrated into existing hydraulic systems.
