Brevini SH7V, SH7VR and SH11C hydraulic motors

The SH7V and SH7VR variable displacement hydraulic motors from Brevini Australia offer significantly improved performance than the previous H2V model, with very high power density and improved efficiency, even at low speeds.

Currently used in drilling rigs in Italy, China, USA and Japan, the SH7 108 and 160 are now field proven for use in heavy-duty transmission applications. Featuring a displacement ratio of 5:1, there are three displacements available from 75-160 cc/rev, with a continuous pressure of 430 bar and peak of 480 bar.

The motors are of bimetal barrel construction, with seven single-piece pistons made from 31CrMoV12. A special carbon coating is used to reduce friction and is sealed with a Viton shaft seal. The 28˚ bent axis angle does away with the need for a joint linking the barrel with the output shaft.

The compact size offers high power-to-weight ratio and can be used in both open and closed loop applications. The SH7V is available in ISO and SAE mount, while the SH7VR is the gearbox plug version.

Brevini has also announced the SH11C fixed displacement motor, featuring a 40° bent axis angle. With 12 displacements up to 180 cc/rev, the motors are suitable both for open and closed circuit application and can be used on heavy-duty applications for industrial applications on stationary machines and on mobile vehicles. The motors utilise convex valve plates to provide high-performance units capable of up to 430 bar continuous and 480 bar peak pressure.
