GEAR MOTORS ALM SERIES
Menu
The ALM Marzocchi gear motors of the ALM1, ALM2, and ALM3 series offer high torque, high volumetric efficiency, and long service life, with a compact and versatile design. Ideal for mobile and industrial applications, they ensure excellent performance even in harsh conditions.
ALM Marzocchi Gear Motors represent a highly efficient solution for industrial and mobile hydraulics. Available in the ALM1, ALM2, and ALM3 versions, these bidirectional and unidirectional motors stand out for:
Wide range of displacements: from 1.4 to 87 cm³/rev
High pressures: up to 270 bar peak
Speeds up to 5000 RPM
Excellent power-to-size ratio
Versions for high and low temperatures
Manufactured with a high-strength extruded aluminum body and case-hardened and tempered special steel gears, they ensure high hydromechanical efficiencies, low noise, and wear resistance.
ALM motors feature:
External drainage (R series)
Various flange, shaft, and port configurations
Compatibility with special fluids and harsh environments
Thanks to the axial compensation system, internal leakages are drastically reduced, improving durability and overall efficiency.
