Field Servo Hydraulic Service, Maintenance & Engineering Consulting

When your testing laboratory faces mechanical downtime or requires system modernization, Servo Hydraulic Solutions delivers rapid, expert field servo hydraulic service and engineering support. Built on nearly 20 years of hands-on global experience, our team of engineers and technicians specializes in troubleshooting complex dynamic testing systems, earthquake simulators, and vibration platforms.

We do not force you into proprietary standard products. Instead, we listen to your operational requirements and provide tailored servo hydraulic consulting to design, upgrade, or maintain your equipment cost-effectively.

Existing Servo Hydraulic Maintenance and Repair

Many testing facilities are burdened by expensive OEM maintenance contracts that restrict replacement parts to proprietary catalogs. We take a smarter, highly cost-effective approach to existing servo hydraulic maintenance and repair:

  • Commercial Off-The-Shelf (COTS) Priority: By utilizing non-proprietary, open-architecture COTS hydraulic and electrical components, we typically deliver comparable or superior maintenance services at roughly half the cost of OEM plans.
  • Legacy System Rehabilitation: Rather than forcing costly full-system replacements, our engineers specialize in breathing new life into underused or older analog servo hydraulic equipment.
  • Digital Controller Upgrades: We revitalize legacy mechanical actuators and manifolds by retrofitting modern digital computer interfaces and automated control software.

Comprehensive Engineering & Laboratory Consulting Services

From component troubleshooting to complete laboratory infrastructure design, our specialized technical capabilities include:

  • Large-Scale Lab Design & Layout: We consult on and engineer complete dynamic testing laboratories—including strong floors and walls, reaction pit foundations, pump rooms, overhead cranes, and hydraulic piping distribution.
  • Hydraulic Power Supply (HPS) Optimization: Designing and servicing open-frame, laboratory-grade hydraulic power supplies with micro-clean filtration and quiet pump room configurations.
  • Turnkey Technical Support: Complete project management, CAD electrical schematics, stress analysis, welding engineering, and custom data acquisition system integration.

Frequently Asked Questions About Servo Hydraulic Services

1. What does your field servo hydraulic service include?

Our field servo hydraulic service includes on-site diagnostic troubleshooting, hydraulic actuator inspection, servo valve replacement, system calibration, digital controller retrofitting, and emergency mechanical repair for testing laboratories globally.

2. Can you perform maintenance and repair on existing servo hydraulic equipment from other manufacturers?

Yes. We specialize in existing servo hydraulic maintenance and repair for a wide range of third-party and legacy testing systems. Because we operate on open-architecture principles, we can service, troubleshoot, and upgrade equipment without proprietary vendor lock-in.

3. How does your COTS (Commercial Off-The-Shelf) approach reduce maintenance costs?

Traditional manufacturers often tie clients to expensive, proprietary replacement parts. By utilizing dependable Commercial Off-The-Shelf (COTS) valves, pumps, and electrical components, we make future repairs simpler, ensure parts are globally available, and typically reduce maintenance costs by up to 50%.

4. Do you offer servo hydraulic consulting for new laboratory design and layout?

Absolutely. Our servo hydraulic consulting team designs and constructs complete testing laboratories. Led by Doug Weller, we assist with structural strong floors, reaction walls, vibration-isolated pit foundations, low-noise pump room layouts, and high-flow hydraulic distribution lines.

5. Can you rehabilitate older or unused servo hydraulic testing equipment?

Yes. We frequently encounter labs with older or decommissioned seismic and vibration equipment. Instead of condemning sound mechanical assets, we revitalize existing hydraulic actuators and manifolds by integrating state-of-the-art computer controllers and automated testing interfaces.

6. Are your field services and consulting available internationally?

Yes. While we are headquartered in Boulder, Colorado, we provide remote diagnostics, engineering consulting, and on-site field service to universities, civil engineering laboratories, and industrial testing facilities across the United States and internationally.

High performance, cost effective, scalable hydraulic power supplies.

Servo Hydraulic Solutions’ Open Frame Hydraulic Power supplies are designed for precision control systems, featuring laboratory-grade pumps and micro-clean filtration for long-lasting, low-maintenance operation. Equipped with interlocks for failsafe continuous operation, these units are ideal for centralized systems serving large laboratories or multiple stations, requiring a dedicated pump room to minimize noise.

Robust motor pump units with oversized stainless-steel reservoirs ensure durability and easy servicing. The hydraulic pump, mounted with a bell housing for perfect alignment and replacement facilitation, is driven by a fully enclosed electric motor via a flexible coupling. The system operates at 1800 RPM (60 Hz) or 1500 RPM (50 Hz).

An oversized stainless-steel reservoir with baffling and diffusers allows air dissipation, with a removable top for easy access and cleaning. Hydraulic control components are integrated into a machined manifold block, facilitating the hydraulic interface with various test systems such as earthquake simulators, vibration testing systems, motion platforms, or shake tables.

Special Areas of Expertise

We frequently encounter underused or unused lab equipment post large experiments. Our engineers specialize in revitalizing existing equipment, breathing new life into it and exploring innovative uses that were previously overlooked.

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

Customers often wonder how to optimize their equipment’s performance. A practical solution is to consult with our experts in your lab. Unlike others constrained by proprietary products or costly upgrades, we advocate for using Commercial Off-The-Shelf (COTS) parts whenever possible. This approach offers flexibility and cost control, providing solutions that others may not offer.

Re-habilitation of Un-used Servo Hydraulic Equipment

Customers often wonder what to do with older equipment. A practical solution is to consult with our experts in your lab. Unlike others constrained by proprietary products or policies against reviving older equipment, we believe in maximizing the use of well-maintained assets. We prioritize using Commercial Off-The-Shelf (COTS) parts, offering flexibility and cost control for tailored solutions.

Maintenance of Servo Hydraulic Equipment

While many companies provide maintenance plans for testing systems, costs can be steep, and they often limit options to their own parts. Due to our smaller size and commitment to Commercial Off-The-Shelf (COTS) principles, we typically offer comparable services at about half the cost. Additionally, we provide recommendations for optimal conditions.

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.
