Stromag launches SHPU range of hydraulic power units
Stromag has launched its all-new range of SHPU hydraulic power packs, which are suitable for use with Stromag hydraulic brakes and clutches. Replacing all previous hydraulic power unit (HPU) models, the new range offers customers simplified specifications, increased modularity and excellent performance rolled into a compact package.
Hydraulic brakes and clutches rely on a supply of pressurized hydraulic fluid from HPUs to operate. Depending on the complexity of the application, HPUs can vary in design and available options. Consequently, specifying a suitable HPU can be challenging. To solve this, Stromag has condensed its old range of HPUs down to three models which offer a full range of options and the performance to operate any of the hydraulic brakes or clutches in the range.
Developed entirely in-house by Stromag, a leading brand of Altra Industrial Motion Corp., the SHPU range is compact and offers high modularity. The SHPU1, SHPU2, and SHPU3 are available for different duty requirements, with each featuring a highly versatile standard architecture for easy customisation. For example, different motors, brackets, and tank sizes can be easily accommodated in the same SHPU model. This inherent flexibility means that the range can cover the full spectrum of hydraulic brake and clutch applications.
Ease of specification is ensured thanks to a public datasheet that shows the performance of every Stromag hydraulic brake when working with each SHPU model. The tables include the opening and closing times for brake and SHPU combinations, with performance data also available for systems incorporating multiple brakes. This useful reference tool allows engineering departments to easily see which SHPU is suitable for specific braking applications and configurations. Furthermore, customers can choose a more optimised solution, whether the SHPU is needed to power multiple fast-closing brakes or a single unit that only opens and closes once a day.
Standardised components, such as the manifold, aluminum tanks, and top motor mounting, are shared across the SHPU range, greatly simplifying the integration of additional features.
