LP11.2
Common rail high pressure pump
The LP11.2 common-rail high-pressure pump is designed for off-highway applications in civil engineering and construction, agriculture and marine environments. With a suitable system design, its robust construction with eccentric drive and oil lubrication can support reliable operation under varying environmental conditions, including low or high temperatures and increased dust exposure. The LP11.2 high-pressure pump meets DNV certification standards for marine applications.
