Numa’s pneumatic lubricators are positive displacement, air drilling, lubrication systems. Our hammer lubes and foam lubrication for DTH hammers are designed to inject rock drill oils into the air line under positive pressure to ensure the proper amount of oil is supplied to the air hammer while drilling. Numa offers hammer lube with a 5 gallon (19 liter) reservoir for 3″ to 6″ hammers, 15 gallon (57 liter) reservoir for 12″ hammers and smaller, or a 45 gallon (170 liter) reservoir for 18″ hammers and larger.
All models offer a positive displacement pump for oil drilling that is capable of pumping up to 20 quarts (18.9 liters) per hour at 1,500 PSI (103 Bar) to pneumatic hammers/bits and pneumatic rock drills. The required supply air pressure is a maximum of 85 PSI (6 Bar) while the supply to output pressure ratio is 17.6:1. The pumps are adjustable for stroke length and number of strokes per minute.
