A new way to prevent varnish buildup

Lubrizol 6776 is designed to meet all of the traditional hydraulic oil requirements but also add a new benefit: It keeps hydraulic systems clean. A formulation containing 1.4 wt.% Lubrizol 6776 in Group I base oils was tested in an extended Eaton Vickers
35VQ-25 pump test that was allowed to run for 1000 hours. The result was a clean reservoir and clean system components.

Case Study on Potential Cost Savings

Large plastic injection molding company
Operates 24 hours/day for 5 days per week
Replaces or cleans 60 servo valves per year
Total cost to customer for valves and labor is $130K/year not including downtime

DIN 51524-2
Meets wear requirements for Eaton Vickers 35VQ-25.

Traditional
vs Clean

Lubrizol conducted extended Eaton Vickers 35VQ-25 pump tests. These tests were run under normal conditions except the test duration was extended to 1000 hours. Time after time traditional fluid technology showed the formation of varnish in the system reservoir and hydraulic components after only 500 hours of use.

Benefits of Lubrizol 6776

Excellent oxidation life, helping to extend life of oil and prevent varnish formation
High level of thermal stability, which helps minimize the formation of varnish
Excellent demulsibility, so water separates quickly
Outstanding antiwear system to protect system components
High level of rust and corrosion protection, extending component life
Excellent filterability
