Servo Hydraulic Services


Servo Hydraulic Solutions is a forward-thinking global, highly interactive company that takes pride in our ability to attract and retain a staff of Engineers, technicians, and consultants who innovate solutions to tough problems.

Servo Hydraulic Solutions allows custom design earthquake simulators, vibration testing systems, shake tables and motion platforms. We will not force you into a standard product. We listen to your specific needs and craft a solution to meet those requirements.

No project is too small, no problem is too challenging. We will always arrive at the optimal solution.

High performance, cost effective, scalable hydraulic power supplies.

The Servo Hydraulic Solutions Open Frame style Hydraulic Power supplies are laboratory quality pumps designed to meet the exacting requirements of Servo Hydraulic Control Systems. These power supplies utilize quality components and micro-clean filtration to provide trouble-free long life with minimum maintenance. A complete system of interlocks and controls allow failsafe unattended continuous operation. These units require a pump room to prevent noise from entering the test cell. They are the perfect match for installations that need one centralized system that provides oil for a large laboratory, or for many stations.

Rugged and serviceable motor pump units are coupled to a common oversized stainless steel reservoir. The hydraulic pump is mounted with a bell housing which provides the pump with perfect alignment and facilitates replacement. Pump drive is from a face mounted, fully-enclosed, fan-cooled electric motor coupled directly via a flexible drive coupling with replaceable insert spider. The pump drive speed is 1800 RPM at 60 Hz (1500 RPM at 50 Hz).

System oil is stored in an oversized stainless steel reservoir, which contains baffling and return line diffusers to allow dissipation of entrained air. The reservoir has a full-size removable top for unrestricted access and clean-out.

The hydraulic control components are incorporated in a machined manifold block, which is mounted on the perimeter of the unit. This manifold serves to provide the hydraulic interface from the pump and reservoir to the test system – be it an earthquake simulator, vibration testing system, motion platform or shake table.

Special Areas of Expertise

We have had many instances of lab equipment being underused, or not used at all after one large experiment. Our engineers will work with the customers to make existing equipment come “back to life” or better yet – give if a new life that was not previously thought of.

Lab Design & Layout of Large Scale Testing Labs

SHS provides dynamic testing systems and also designs and constructs entire testing laboratories. These include such components as strong floors and walls, flat and pit foundations, control rooms, pump rooms, overhead cranes, lab buildings, information technology, and similar infrastructure. Contact SHS to discuss custom laboratory designs to meet your testing needs.

Up Grading Existing Servo Hydraulic Equipment

Our engineers often find customers asking themselves the question “how do I get more performance out of my equipment?” A reasonable solution is to call in one of our experts and have a chat at your lab. We have many solutions that others can’t use because they are tied to the company products, or their up-grades are more expensive than the original parts. We bring a philosophy of using Commercial Off The Shelf (COTS) parts whenever we can. This allows us to be more flexible, and keep costs under control.

Re-habilitation of Un-used Servo Hydraulic Equipment

Our engineers often find customers asking themselves the question “What can we do with some of the older equipment we have on hand?” A reasonable solution is to call in one of our experts and have a chat at your lab. We have many solutions that others can’t use because they are tied to the company products, or their policies are to not bring the older equipment back to life. Our belief is if it’s still in good shape, why not use it? We bring a philosophy of using Commercial Off The Shelf (COTS) parts whenever we can. This allows us to be more flexible, and keep costs under control.

Maintenance of Servo Hydraulic Equipment

Many companies offer some type of maintenance plan for their testing systems, but the costs tend to be pretty high for the work, and they only offer their parts. Because of our smaller size, and our COTS philosophy, we can usually offer the same service for about ½ the cost that others are able to do. We will also make recommendations about the conditions around us.

Doug knows what he is doing. He has great technical skills in hydraulic actuators, controlling system, and data acquisition. Doug did a great job for us building new actuators for quasi-static testing.

About Servo Hydraulic Systems

Led by Doug Weller, Servo Hydraulic Solutions in Boulder, Colorado uses commercial off-the-shelf components allowing a unique end product-be it an earthquake simulator, vibration testing system or earthquake shake table.

We listen to customers and propose ideas that support your individual needs. Our goal is for our customer to be heard and well taken care of. With nearly 20 years of installation experience and testing, we offer solutions that better fit our customer’s needs. We also provide remote services in the US and abroad.

If you have a current system that is not fully functioning, Servo Hydraulic Solutions can troubleshoot and add computer interfaces bringing the old system back to life. Analog systems may need updating. With our experience and wealth of knowledge, we are confident working on existing shake tables.

We utilize local labor and materials more than most companies. It is our opinion that this increases the quality of the product as local workmen have a sense of responsibility to the project. We firmly believe that when local professionals are used, those skills to maintain your system stay with you, thus avoiding unnecessary service calls. We want to save you money when possible.
