Common rail high pressure pump LP11.6

The LP11.6 Common rail high pressure pump is designed for large diesel engines, which are primarily used in the mining industry, in marine and rail applications, but also in stationary applications. With a compact and lightweight design combined, variable connection options and directions of rotation, the pump offers engine manufacturers maximum flexibility in engine architecture. The service life of the rugged high pressure pump is independent of the quality of the fuel thanks to its oil lubrication.
