What Dynex does
Dynex/Rivett Inc. designs and manufactures high-pressure hydraulic components and integrated systems for industrial and mobile machinery, with a stated operating history of over 60 years and products rated up to 20,000 psi (1380 bar). The portfolio centers on a proprietary checkball piston pump architecture (PF and PV series), offered in fixed displacement and pressure-compensated variants, complemented by a full valve family (NFPA D03/D05/D08 directional control valves, HP-series high-pressure valves, 8800-series and VP/H8819 proportional pressure control valves, VST/VM seated and poppet valves, VSW sandwich valves), MF5000 hydraulic motors, remote proportional actuators, and hydraulic power units (QuickPack, motor/pump, and custom systems). Differentiated technologies include Split-Flow pumps delivering up to eight independent flows from a single pump, cold-weather operation to -58°F (-50°C) on the PF500-LT, and IACS-certified marine pressure-compensated pumps.
The company sells through three revenue streams: catalog hardware, custom-engineered systems built at its Ashland Power Units Division, and aftermarket service parts. Go-to-market combines direct technical sales with a worldwide authorized distributor network anchored by SunSource (oil & gas), HTM Group, Berendsen Fluid Power, and FP Hydraulique, plus industry trade show presence (OTC, MRO Americas/Europe, MINExpo, Kormarine, SPE Offshore Europe, Fabtech). Dynex is privately held with no disclosed institutional investors and is structured as a US corporation headquartered in Pewaukee, Wisconsin, with a manufacturing facility in Ashland, Massachusetts, and a sales office in Dubai (opened 2022). Customer base spans oil & gas, aerospace ground support, mining, marine, heavy lifting and structural jacking, steel and aluminum production, power generation, tunneling, and general industrial sectors, with named enterprise engagements in nuclear bolt tensioning (Hydratight) and press retrofit (Enprotech).
