Numa’s pneumatic lubricators are positive displacement, air drilling, lubrication systems 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 multiple versions including:
♦ 5 gallon (19 liter) reservoir for 3″ to 6″ hammers
♦ 15 gallon (57 liter) reservoir for 12″ hammers and smaller
♦ 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.
