Product catalog summary
Overview: The LP7.2 is a high-pressure pump designed for heavy-duty on and off-highway engines. It features an oil-lubricated drive, ensuring reliability in harsh conditions. Its compact design (252x110x230 mm) and lightweight (approximately 7 kg) make it versatile for various engine applications.
Specifications: The pump operates at a system pressure of 250 to 2,500 bar with a maximum flow rate of 265 l/h. It has a rated pump speed of 3,500 rpm at 2,500 bar and a maximum speed of 4,500 rpm at 1,800 bar. The drive concept is a roller tappet with two plungers, and it uses engine oil for lubrication.
Features: Key features include high hydraulic efficiency with digital inlet valves, a mechanical G-rotor feed pump, and compatibility with Euro VI, US 10, EU Stage V, and US EPA Tier 4f standards. The pump is designed with customized engine interfaces and offers variants with different rotation directions and connection orientations.
Technical Data: The pump's service life is 1.6 million km for on-highway use and 15,000 hours for off-highway use. It operates in ambient conditions ranging from -30 °C to 125 °C and adheres to vibration specifications VDI 3838 / ISO 10816-6. Fuel purity class is 12/9/6 (ISO 4406) with a filtration efficiency of at least 98.7% at 5 µm (ISO 19438).
Applications: The LP7.2 is suitable for on-highway, agriculture/forestry, civil engineering, and power generation applications.

Common Rail High Pressure Pump LP7.2-1

Short Description The LP7.2 high pressure pump is developed for heavy-duty on and off-highway engines. Like all of Liebherr’s common rail high pressure pumps, the LP7.2 also has an oil-lubricated drive, making it reliable even in harsh environmental conditions. The lightweight and compact design with external dimensions of 252x110x230 mm (LxWxH) and a weight of approximately 7 kg makes it easy to use in a wide variety of engine applications. With regard to its installation space, the roller tappet pump with cam drive has a high flow rate of 265 l/h at a system pressure of up to 2,500 bar. Digital inlet valves control fuel delivery and help to accurately determine the amount of fuel delivered to each cylinder individually. This increases hydraulic efficiency by up to 10 % compared to a volumetrically-controlled pump. Variants with different directions of rotation and variable connection orientation as well as flange geometry are available. Features • Pressure level 2,500 bar • Oil-lubricated • Cam drive • High hydraulic efficiency with digital inlet valves • Lightweight and compact pump design • Customised engine interfaces • Mechanical G-rotor feed pump • Euro VI, US 10, EU Stufe V, US EPA Tier 4f compatible
