When you need maximum power, durability, and performance, Foster Hydraulics delivers diesel hydraulic power units that are engineered to handle the most demanding conditions. For decades, we’ve been the trusted name in custom-built hydraulic solutions, serving industries nationwide with equipment designed for efficiency, reliability, and long-term performance. Whether your operation is on the Alaska tundra, an oil rig in the Gulf of Mexico, or anywhere in between, our diesel power units are built to keep your work moving.

Our diesel hydraulic power units are built stronger than industry standards—because heavy-duty should mean more than just a label. We use premium diesel engines from John Deere, Kubota, and Kohler, paired with thermostat-controlled heat exchangers, reservoir heaters, and pressure-compensated pumps to ensure smooth operation in even the harshest environments. Every unit can be customized with a range of hydraulic control valves, larger fuel tanks for extended run times, and oversized reservoirs for better heat management and improved system longevity.

No two projects are alike, and that’s why we offer fully customizable diesel hydraulic power units. From pump specifications and tank size to control valve configurations and specialized coatings, our team will design and build a system that meets your precise operational requirements. Optional features such as marine-grade powder coating, protective cages, crane lift points, and advanced flow meters ensure your power unit is ready for any job site. We also offer mobile and compact diesel units for projects that require portability without sacrificing performance.

Each diesel hydraulic power unit is designed for maximum efficiency, with features like electronic engine control consoles, heavy-duty skid platforms with forklift access, and electric start systems. Our standard models are available with multiple pump options—ranging from 10 GPM at 3,000 PSI to 15 GPM at 2,000 PSI—making them ideal for applications such as dewatering pumps, walking floors, and other high-demand hydraulic needs. With lead times as short as 7–10 business days for standard builds, we’re committed to delivering both speed and quality.

At Foster Hydraulics, we’ve been manufacturing high-performance hydraulic equipment since 1978. As a second-generation family-owned business, we combine decades of expertise with a dedication to customer satisfaction. Every diesel hydraulic power unit we build is backed by our commitment to quality, customization, and service you can trust.
