Technical data

Highlights

With its robust design, the LP11.2 Common rail high pressure pump is ideal for demanding off-highway applications in the building construction and civil engineering, agricultural and maritime sectors. Even in challenging environmental conditions such as extreme temperatures or high levels of dust, the combination of eccentric drive and oil lubrication ensures a long service life. Thanks to its robust construction and high efficiency, the high pressure pump is also ideally suited for use in on-highway applications.
