Your Single Source for Fluid Power:
Design, Build, Service

Grimstad designs, builds, and services complete fluid systems in-house, from hydraulic power units and custom manifolds to component distribution and capital equipment. As both an OEM and a systems integrator, we bring every piece together, engineering, manufacturing, and support, under one roof.

Custom Hydraulic Power Units

Grimstad designs, builds, and tests hydraulic power units ranging from 2 to 2,000+ gallons, engineered for precision and repeatable performance. Packaged systems can include integrated electrical controls, with custom paint capability available to match your equipment standards. Every HPU is designed, built, and tested in-house before it ships.

Custom Manifold Assemblies

Custom manifold assemblies are designed in-house, built to handle nitrogen, air, or oil depending on your system’s needs. We offer the full range of valve configurations, including top-mounted, slip-in, and screw-in cartridges, to fit your application. Every manifold is built to trusted quality standards to ensure consistent performance on every job.

Electrical Controls

Electrical control panels are designed, built, and tested in-house through a UL508A certified shop, with on-staff programmers supporting a range of control platforms to match your system’s needs. Panels are built to NEC standards and backed by Rockwell Automation System Integrator expertise for tightly integrated automation. Every panel is fully tested before it leaves the shop, so it’s ready to run the moment it’s installed.

Component Distribution

Grimstad partners with premier product lines across pumps, valves, cylinders, filtration, instrumentation, and more, backed by a network of trusted industry partners. Our team helps match the right component to your application, whether you need a single part or an ongoing supply solution. With decades of applied hydraulic expertise behind every recommendation, you get the right part the first time.

Mooring Winch Sales & Repair

We are a trusted source for Collomatic mooring winches, serving Great Lakes vessels, marine terminals, and shipping operations that demand reliable, heavy-duty winch performance. Our team provides new Collomatic winch units, rebuilds, and on-site repair, ensuring safe and dependable mooring operations for commercial marine fleets.



Metal Baling & Recycling Equipment

We supply and support Galland Henning scrap balers, including cover balers, shear balers, and full baler systems built for high-volume metal recycling operations. From new equipment sales to parts and field repair, we help scrap yards, recyclers, and metal processors keep their baling equipment running at peak capacity, backed by genuine OEM parts and decades of applied hydraulic expertise.

Field Service and Repair

GT Hydraulics, our in-house service team, keeps your equipment running with installs, field repair, rebuilds, and on-site support backed by decades of applied hydraulic and electrical expertise. From new equipment installation to ongoing maintenance support, our technicians work to minimize downtime and get your equipment back in operation fast. Every repair is backed by our premier distribution network, so the right parts are always within reach.

Engineering Services and Design

Grimstad’s in-house engineering team acts as an extension of your engineering department, from initial concept and sizing through 3D design and system integration. Our engineers bring decades of applied fluid power and electrical controls experience to solve application-specific challenges, not just spec parts. Whether you need a full custom system designed from scratch or support optimizing an existing one, we’re involved from the first conversation through startup.
