Numa products

Outdistances competitive hammers in both speed and longevity. Simplified hammer design with less internal components. Drills at high frequency to provide less vibration and smooth operation. More efficient design requires less air which equals fuel savings. Designed to operate at pressures up to 500 PSI (34.5 BAR). Ability to drill efficiently against high heads of water.

Valveless down hole hammer design. Designed to operate at pressures to 500 PSI (34.5 BAR). Reversible non-ported piston case for extended life. Ability to drill efficiently against high heads of water. Superior directional stability in horizontal applications. Ejecting cuttings through the collection tube eliminates traditional hole cleaning problems. Environmentally sensitive - no foam required for hole cleaning & lubricants are not free to contaminate the formation. Collection tube is easily replaced without hammer disassembly. Metering sleeve facilitates sample flow through collection tube

Valveless down hole hammer design. Ability to drill efficiently against high heads of water. Designed to operate at pressures up to 250 PSI (17.0 BAR). Reversible non-ported piston case for extended life.  Superior directional stability in horizontal applications. Ejecting cuttings through the collection tube eliminates traditional hole cleaning problems. Environmentally sensitive- no foam required for hole cleaning and lubricants are not free to contaminate the formation. Typical vertical and horizontal applications include: caissons, piles/rock sockets, tunneling underloads, foundation drilling and other jobs where large volume rock excavation is required.

Valveless down hole hammer design. Ability to drill efficiently against high heads of water. Designed to operate at pressures up to 200 PSI (13.6 BAR).  Superior directional stability in horizontal applications. Ejecting cuttings through the collection tube eliminates traditional hole cleaning problems. Environmentally sensitive - no foam required for hole cleaning and lubricants are not free to contaminate the formation.. Typical vertical and horizontal applications include: caissons, piles/rock sockets, tunneling under roads, foundation drilling and other jobs where large volume rock excavation is required
