Marzocchi Pompe has renewed its own range of products with the ALM (ALM1, ALM2 e ALM3) and GHM (GHM1, GHM2 e GHM3) external gear motors, suitable for the widest range of application, both in the industrial and the mobile field.

Marzocchi's external gear motors consist of a gear pair supported by a securing flange, a body,  two aluminum bushings and a cover. The low noise level during motor operation is ensured by the proper tooth profile design.

The ALM and GHM series motors from Marzocchi can be supplied in both unidirectional and bidirectional configurations.

Upon request, they can also be supplied with pressure regulation and check valves.

These motors are without external drain and can be used with counterpressures of maximum 6 bars; they can be used in both left or right configuration. The available displacements for the ALM1 and GHM groups are between 1.4 to 13.8 cc/rev, for the ALM2 and GHM2 groups are between 4.5 to 35.2 cc/rev while for the ALM3 and GHM3 group are between 20 and 87 cc/rev.

A very good power/weight ratio and power/sizes ratio are allowing a wide range of displacements (between 2.8 and 87 cc/rev) within each of the three groups.
