Dynex Power Units & Systems
Dynex hydraulic power units for high pressure and special fluids

Standard or Specialized Power Units for
High Pressure and Special Fluids


Select from a wide range of standard hydraulic power units. Systems are available for pressures from 3000 to 15 000 psi (210 to 1400 bar), with flows to 200 gpm (757 L/min).

Specify units for operation with various fluids: standard mineral-oil or low-lubricity fire-resistant and water-based fluids, including water glycol, Skydrol, other phosphate ester fluids, and various military fluids.

Specialized systems with custom fabrication are made to meet specific customer requirements. These custom power units can be built for high pressure operation to 15 000 psi (1040 bar).

Dynex hydraulic systems have been used worldwide for over 45 years in a wide range of indusrial and mobile applications.

See the Standard Selection Table below.

NFPA and JIC Standard Hydraulic Power Units

The Dynex power unit facility employs 3D CAD design and manufacturing techniques that adhere to NFPA and JIC guidelines.

Plasma cutting and MIG and TIG welding are used to assure quality fabrication. Custom tube-bending equipment can handle up to 1.5 inch (38,1 mm) diameter stainless steel.

Systems with Expert
High-Pressure Piping

Skilled workers with experience piping for high-pressure systems assure trouble-free operation. Port connection options include NPT, SAE, flange, socket weld, coned and threaded (Autoclave or Butech) and BSP (British Standard Pipe) fittings.

These power units provide long service-life and reduced maintenance with the use of metal tubing and custom bends where suitable. Stainless steel reservoirs, tubing and fittings can also be incorporated.

High pressure 10000 psi power units for special fluids

Hydraulic power units include high pressure HPVT Series, which operate to 10 000 psi (700 bar). These units are suitable for mineral oil, water glycol, Skydrol or other phosphate ester fluids. Because many conditions affect operation, review your special fluid application with the power unit sales department.
 

Custom Systems

Custom power units are made to meet exact customer specifications. Systems can operate to 15 000 psi (1040 bar) with reservoirs to 500 gallons (1893 L) and prime movers to 700 HP (522 kW). Learn more about custom systems.
