Common Rail high pressure pump LP11.5

The LP11.5 Common Rail high pressure pump is specially designed for large diesel engines, which are used primarily in mining, power generation, maritime and rail applications. Here, the oil-lubricated high pressure pump impresses with its long service life and exceptional reliability even under the harshest environmental conditions. The small difference between mean and peak torque also has positive effects on the wheel design and noise production.
