Testimonials
Mayer Brothers Construction improved roller efficiency using LE's 7500 MONOLEC Power Fluid.
key takeaways
Challenge
Using a commercial-grade lubricant led to high heat, causing viscosity breakdown and fluid degradation, which resulted in mid-day fade and power loss.
LE solution
LE’s 7500 MONOLEC® Power Fluid is recommended for combination gear-hydraulic systems, hydraulic transmissions, wet brakes, and torque converters due to its nonfoaming properties and ability to reject water.
Results
Using LE’s 7500 lubricant resulted in a 59°F cooler pump temperature, 40°F cooler reservoir, and 45°F lower oil cooler temperature compared to commercial-grade lubricant, potentially extending the life of the oil and equipment.
Customer Profile
Mayer Brothers Construction Company Inc. is an asphalt paving company located in Erie, Pennsylvania. They have been in business since the late 1800s and have been an LE customer since 1980.
Application
Mayer Brothers uses 3 to 5-ton Dresser pavement rollers.
Challenge
While using a commercial-grade lubricant, they were experiencing high heat, which caused viscosity and fluid breakdown that resulted in mid-day fade and lack of power.
LE Solution
The local LE Representative recommended 7500 MONOLEC® Power Fluid. LE’s 7500 is designed for combination gear-hydraulic systems, hydraulic transmissions, wet brakes, and torque converters. It is nonfoaming in service and rejects water.
Results
They used two identical pavement rollers on the same job on the same day. After nine hours, the temperature of the pavement roller using the commercial-grade lubricant read 287°F, compared to the pavement roller using LE’s 7500, which read 228°F at the pump. That is a 59°F difference! The pavement roller using LE’s 7500 also read 40°F cooler in the reservoir and 45°F lower at the oil cooler than the pavement roller using the commercial-grade lubricant. Lower temperatures typically increase the life of both the oil (less oxidation) and the equipment (less friction).
