Powerful hydraulic tools require reliable power sources.
That powerful hydraulic tools require great power packs is no secret. In cooperation with MAN Diesel, Wärtsilä and 2-stroke engine owners worldwide, Chris-Marine has developed a range of mobile Hydraulic Power Units (HPUs). When needed, he units deliver up to 5 times the normal speed when needed, while fulfilling the requirement for pressures above 3000 bar.

These Power Packs can loosen a cylinder cover on the world’s largest diesel engines in less than five minutes, which makes them very useful tools. 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 safely operate several types of tool series with one unit only.
About the HPU range
A series of power units covering most needs for most engines
Q: What’s the most efficient way to loosen a cylinder cover?
A: 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.
Q: Are Chris-Marine’s HPUs more reliable and faster than power packs of other brands?
A: Chris-Marine HPU’s are all equipped with internal pumps produced in-house as well as high-pressure high pressure pipes, connections and gauges of highest technical European standards. Heavy duty workshop versions are equipped with Twin or double acting pumps, which ensures stable performance and reduces operation time with up to 80%.

Q: Can Chris-Marine HPUs be powered by hand ?
A: All Chris-Marine power units are as standard pneumatically driven for faster and more stable performance. However, a few models (HPU 1500/1500-2) are also hand driven in case air supply is not available.

Q: What is the expected lifetime of Chris-Marine’s Power Packs?
A: When the recommended maintenance instructions are followed for the particular HPU model and genuine spares/consumables are used, the unit is expected to be operational for approximately the average lifetime of a freight vessel i.e. 20 years.
Q: Just how important is it to have a well-functioning hydraulic power unit onboard?
A: Without a hydraulic power unit, like HPU, you can’t finalize engine maintenance. You risk ending up in a costly off-hire situation.
