MTS Systems
Landmark® Servohydraulic Test Systems
From complex thermomechanical fatigue studies to standard tension and compression tests, MTS Landmark systems deliver accurate, repeatable results.
MTS Systems — HPU
SilentFlo™ 515 & 525 Hydraulic Power Units (HPU)
With features that maximize electrical efficiency and minimize water consumption, and options for remote monitoring of pressure, temperature and fluid level, these HPUs will help reduce facility energy costs. For additional energy savings, the larger units can be equipped with a run-on-demand option that reduces electrical power and cooling water consumption when the system is not running at full capacity.
Key Features & Benefits
- Energy Efficient — New Model 525 HPU reduces energy use by 35% or more compared to older HPUs
- Cost Efficient — Easy to install pump/motor modules add capacity at a fraction of the cost
- Innovative Technology — Remote monitoring and control options available
- Quiet Operation — Up to 30 dB(A) quieter than conventional HPUs
