Hydraulic Power and Distribution


MTS offers an extensive portfolio of components and systems designed to maximize safety, reliability and energy-efficiency of hydraulic power generation and distribution. These systems are renowned around the world for producing minimal ambient noise levels while delivering exceptionally well-controlled power across a wide range of testing environments.  MTS also provides complete hydraulic system design and integration support to test labs around the world. For more than 40 years, MTS has amassed extensive expertise in the engineering, fabrication and installation of hydraulic hardline and distribution systems, from simple piping to highly complex networking schematics developed prior to facility construction.

Decisions related to hydraulic power and distribution have a profound impact on lab productivity, and should be given the same attention as the test systems themselves. MTS engineers can work closely with you to assess current and future requirements, applying sound engineering practices to make sure you have the safest, quietest, and most efficient system possible.


HPU, pump, fluid power, SilentFlo, Silentflow; 505; Hydraulic Power Unit

MTS SilentFlo™ Hydraulic Power Units (HPUs) deliver superior performance in servohydraulic testing applications.  Operating at or below sound levels commonly found in labs and factory floor environments, the SilentFlo HPU can be deployed directly in the lab, eliminating the need for costly pump housing facilities and reducing supply line length and space requirements.

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.



Hydraulic Service Manifold - manifold; HSM; 293; pressure; flow; accumulator


MTS Hydraulic Service Manifolds (HSMs) provide independent pressure regulation for the precise control, isolation and distribution of hydraulic fluid to test stations.  By installing MTS HSMs into the hydraulic lines between the HPU and servovalve, you can turn each hydraulic circuit on or off and independently set low-pressure levels. This allows convenient, efficient test setup, operation and maintenance of individual test systems without disturbing other systems.

MTS HSMs also minimize the effects of the rapid application and removal of high pressure, reducing unexpected actuator movement that could damage the test article or the test system. They also provide rapid pressure reduction to ensure safety, as well as store energy for transient events that require peak performance.



Hardline & System Design - hardline options and placement, the materials, pipe sizes, and bend radii


When considering hardline options and placement, the materials, pipe sizes, and bend radii will all affect the efficiency and reliability of the hydraulic distribution system. Careful engineering and proper system design can improve test data integrity and maximize lab productivity.  On the other hand, one of the results of faulty design is oscillation—noise ripple—that can be carried by the hydraulic fluid throughout the system. These oscillations have the potential to impair test results. Configuring accumulators and other suppression devices into the system can help eliminate the problem.

We understand the demands of hydraulic distribution system design and installation and can help evaluate tradeoffs to create a system that meets your needs, both functional and economic. When you choose to modify or expand your system, we can help determine the best way to accommodate the change. And throughout your testing experience, we can provide the services you need to prolong the life of your equipment and keep your system operating safely, smoothly and reliably.



Isolation Manifold  - 225W


The MTS Isolation Service Manifold (ISM) controls the hydraulic fluid flow through your test system during power on, power off and in the event of a system problem or E-stop, to help you better protect your lab personnel and assets. This manifold is placed between the hydraulic power unit (HPU) and the hydraulic service manifold (HSM) to prevent system over-pressurization, provide full system pressure discharge, and allow for full hydraulic power isolation downstream of the device.  In the event of an unexpected system shutdown, the ISM performs a cascading sequence to bring the entire distribution system down in a controlled manner, while a redundant over-pressurization relief valve protects the test system nearest to the device. This consistent and purposeful control of your hydraulic distribution system allows you to meet the most recent European Norm (EN) machinery safety standards, including EN 13121, EN 13849-1, and EN ISO 4413.  Easy to set up and maintain, this manifold is a simple way to regulate flow control and improve safe operation throughout your hydraulic system.



Multi-Pump Control Manager


The MTS Multi-Pump Control Manager (MPCM) provides instant, visual access to your hydraulic system’s operational state from a centralized location. With a large touchscreen display you can monitor fluid demand, control fluid supply and balance the load to distribute hydraulic fluid power when and where it is needed. This ability to monitor and control your HPUs as a single system will help improve productivity, reduce energy costs and prolong equipment life.  You can turn on and off individual pump modules to selectively regulate hydraulic flow or you can set minimum flow requirements and then use the Run-on-Demand feature to let the system distribute the flow accordingly to minimize pump wear.

Additional options for the Multi-Pump Control Manager are designed to further enhance the productivity of your hydraulic distribution system. The MTS Station Flow Manager allows test station operators to input their anticipated hydraulic power needs, so that the MPCM can allocate hydraulic fluid efficiently. The System Status Light Bar provides at-a-glance visibility to the state of the hydraulic distribution system, allowing operators to more easily troubleshoot hydraulic flow issues.
