Lubrication Pumps L Series

Model: 000LE, 00LE, OLE, 1LE, 2LE, 5LE

The L Series Lubrication Pumps by Ingersoll Rand represent the pinnacle of engineering excellence in industrial lubrication and fluid transfer systems. With a history of innovation and precision design, these pumps cater to a variety of industries, ensuring reliable performance and maximum operational efficiency.



Ingersoll Rand L Series Lubrication Pumps – Precision and Durability

Advanced Internal Gear Design

At the heart of the L Series lies an internal gear design that ensures smooth, pulse-free flow. This technology minimizes energy loss, making the pumps highly efficient, high performance and ideal for lubrication systems, oil circulation, and low-pressure hydraulics.


Durability and Reliability

Constructed with cast iron housing, the L Series pumps are built to last in demanding environments. The pumps can handle fluid, high temperatures up to 475°F (246°C) and pressures reaching 500 PSI, making them ideal for heavy-duty applications in manufacturing, automotive, and energy sectors.


Materials of Construction

To ensure durability and compatibility, the L Series pumps are constructed using high-quality materials:

  • Housing and Cover: Cast iron (ASTM A48 standards).
  • Rotor and Idler: Steel components designed for stress resistance.
  • Seals and O-rings: Viton as standard, with Neoprene and EPR options available for specific applications.

Energy-Efficient Performance

The internal gear design of the L Series minimizes energy loss, making it one of the most efficient lubrication pumps in its class. Its smooth operation reduces wear and tear on system components, ensuring long-term savings on maintenance and operational costs.


Why Choose the L Series?

The L Series Lubrication Pumps are trusted by industries for their:

  • Exceptional Reliability: Heavy-duty construction ensures continuous operation under demanding conditions.
  • Ease of Installation: Designed with multiple mounting options, moving parts for easy integration.
  • Low Maintenance Requirements: Durable components reduce downtime and extend service life.

Compliance and Safety

The L Series meets international standards, including ATEX compliance, ensuring safe operation in hazardous environments. These pumps are UL listed for power-operated pumps in fuel oil service, providing additional peace of mind.


Conclusion

The Ingersoll Rand L Series Lubrication Pumps are the power generation, ultimate solution for industries seeking reliability, efficiency, and durability in their lubrication and fluid handling systems. With decades of proven performance, these pumps continue to set the standard for industrial excellence.


  • Compact Design:
    Its compact size enables easy integration into both new and existing setups, saving valuable space.

  • Reversible Flow:
    The ability to support bidirectional flow increases adaptability for OEM lubrication systems and diverse fluid transfer needs.

  • Single Mechanical Seal:
    Ensures leak-free operation even under high pressures, increasing reliability and safety.
