Dynex Inc. in Pewaukee, WI, US (United States)

Dynex manufactures hydraulic components and systems for use on mobile and industrial machinery. These pumps, valves, motors and power units have been sold worldwide for over 40 years. 

Dynex has over 40 years experience building power units ranging from small portable power packs to large custom systems. These specialized units operate at pressures to 15 000 psi (1000 bar) and flows to 200 gpm (757 L/min). 

Dynex PF1300 and PF4300 Series hydraulic pumps are approved for use with various water glycol fluids. This makes them ideal for use in the oil & gas industry, for offshore applications on wellhead safety control systems and subsea systems. 

Dynex fabricates specialized hydraulic power units ranging from simple pump/motor units to large 500 gallon (1893 L) hydraulic systems. Prime movers are available to 700 HP (522 kW). 

Individual piston check valves direct flow from the inlet side of the pump to the outlet port in these high pressure hydraulic pumps. The positive-seating checkball valves provide better wear and high volumetric efficiency, especially at high pressure.
