Gear Motors GHM Series Product Range Produced in three different groups with very good power/weight ratio and power/size ratio allowing a wide range of displacements within each group (between 2.8 and 87 cc/rev). The wide range of allowed speeds, the excellent functionality also on their use in series, with strong counter-pressures and limited drain, give to motors of the GHM series very good characteristics even starting under load. The drain is always external and it is through a thread port on the cover. Arange of flanges, shafts, inlet and pressure ports are available. These motors are without external drain and can be used with counter-pressures of maximum 6 bars; they can be used in both left (GHM...S) or right (GHM...D) configuration. The available displacements for the GHM1 group are between 1.4 to 11 cc/rev, for the group GHM2 between 4.5 to 28.2 cc/rev while for the group GHM3 between 20 and 87 cc/rev. For applications that require counterpressures higher than 6 bar please contact jbj Techniques technical office, email: info@jbj.co.uk or telephone: +44(0)1737 767493. Mono-directional motors.
