Numa Lubrication System

Extend the Life of Your DTH Hammer

DTH lubricators

Numa’s pneumatic lubricators are positive displacement, air-operated, lubrication systems. Our lube for DTH hammers is designed to inject rock drill oil into the air line under positive pressure to ensure the proper amount of oil is supplied to the DTH 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 that is capable of pumping up to 20 quarts (18.9 liters) per hour at 1,500 PSI (103 Bar). 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.
