Properties
The Groeneveld BreakAlube-3 pump unit has been specially developed for use on an excava-
tor equipped with a hydraulic hammer.
Characteristics:
• Variable grease delivery between 0.2cc and 4cc per minute with an activated hydraulic
hammer;
• Monitoring of the grease delivery by the pump;
• Monitoring of any exceeding of the maximum admissible grease pressure (300 bar);
• Monitoring a minimum threshold grease pressure (20 bar) each grease cycle;
• Monitoring of the minimum grease level in the reservoir;
• Monitoring of the electrical connections and components;
• Possibility of switching off the hydraulic hammer if the greasing system is no longer func-
tioning, e.g. due to an empty reservoir.
