Hydrex 5003 - Ultra high pressure hydraulic system for expanding heat exchanger tubes with a minimum internal diameter of 7,00 mm ( 0.276" )

Hydraulic expansion finds its best application in the expansion of welded tubes for the fixing of the tube in the tube sheet hole, thanks to its exceptionally fast and competitive "single pass" execution, especially for expansion lengths exceeding 100 mm ( 4" ) where it replaces traditional expansion.

Attentive to the increasingly stringent specifications dictated by designers in the petrochemical field, Maus Italia has designed and built the Hydrex 5003, a fourth generation product which has, over more than 15 years, garnered the approval of its customers.
An evolution of the preceding model, the Hydrex 5003 features:

  • Very high pressure max 5000 bar
  • Continuous control of the very high pressure with digital programming
  • A new lightweight model of probe holder fitted with a highly ergonomic handle
  • Updating of the mechanics and electronics which makes it easy to use and flexible
  • New software that allows you to export/print various work reports

Control console Hydrex 5003



Control console with 9" touch screen display for intuitive control of all working parameters.

Thanks to the use of a last generation touch screen control panel, the Hydrex 5003 is extremely simple to learn and use on a daily basis.

  • The CCP software, designed by Maus Italia, allows the continuous control of the high pressure needed for expansion in order to eliminate out-of-tolerance expansions.
  • The SAC software is an advanced calculation system for determining the working pressure according to the characteristics of the tube and the tube sheet.
  • Capacity to store work reports and save on a memory stick programs and reports of pressure values.
