Portable Hydraulic Power Units for all hydraulic tools

Powerful hydraulic tools require reliable power sources. In cooperation with MAN Diesel, Wärtsilä and 2-stroke engine owners worldwide, Chris-Marine has developed a range of mobile Hydraulic Power Units HPU delivering up to 5 times the normal speed when needed, while fulfilling the requirement for pressures above 3000 bar. 

An HPU unit from Chris-Marine can loosen a cylinder cover on the world’s largest diesel engines in less than five minutes. The HPUs are not only suitable for closed-circuit tools, but can also be used for floating of camshafts as well as opening of SKF couplings. Special operation modes make it possible to operate several types of tool series safely with one unit only. 

Pneumatic-hydraulic power supply for hydraulic tools 

  • For operation of engine hydraulic tool series, i.e. hydraulic jacks
  • Internal pump(s), high-pressure pipes, connections, gauges etc are of top technical quality to ensure reliability and efficiency 
  • A series of power units covering most needs for most engines
  • Smaller units can also be powered by hand 
  • Can be adapted for special applications like opening SKF couplings, opening/separating turbo chargers etc.
  • Twin-pump models drastically reduce pumping time with about 80% of normal time, typical pumping time for a cylinder cover will be 2-6 minutes depending on engine size
  • Hydraulic pressure up to 3,500 bar @ 7bar air inlet pressure
  • Flow rates up to 1.9 l/min
  • Adjustable maximum outlet pressure for tool protection
  • Back-up hand power (optional)
  • Hoses and couplings (optional)
