Dynex/Rivett Inc. manufactures hydraulic components and systems sold worldwide for over 60 years. These products are used in demanding and critical applications on mobile, industrial and marine machinery.

Dynex pumps, motors, valves and power units provide long life, solving the toughest application problems, including high pressures and extreme temperatures. They operate reliably in dirty environments, under harsh conditions, with long, difficult duty cycles.

Checkball piston pumps operate at pressures to 20,000 psi. These pumps operate with mineral oil, and with a wide range of low-lubricity, low-viscosity fluids, including water glycol, Skydrol, Viscor, MIL-spec and other special fluids.

Dynex also manufactures 10,000 psi directional control valves, 15,000 psi pressure control valves, piston motors, electrohydraulic actuators, and custom hydraulic systems.

Dynex sells to customers in over 60 countries, through 40 worldwide distributors. The main manufacturing facility and headquarters is located in Pewaukee, WI, U.S.A.

Power units are fabricated in Ashland, MA, U.S.A. Specialized systems range from pump/motor units to large 200 gallon systems. Workers with experience piping for high-pressure systems assure trouble-free operation at pressures to 15,000 psi. Prime movers are available to 200 HP. For more information contact:
