Thompson, CT USA - Numa, a leading designer and manufacturer of down hole hammers and bits, has introduced the Numa Champion 80 ME down hole hammer. This new design is perfectly suited for all drilling applications in the water well, construction, mining, quarry, oil & gas and environmental industries.

The Champion 80 ME enters the drilling market with a simplified hammer design. That was accomplished by eliminating several internal components and attaching the feed tube assembly within the backhead of the hammer. These changes promote much better alignment of all internal hammer parts resulting in longer hammer life, improved overall hammer performance and most importantly, faster penetration rates. Numa's Champion 80 ME stacks up as one of the fastest hammers in the industry today.

The new Champion 80 ME is capable of drilling holes 7-7/8" to 10" (200-254 mm) in diameter and has an overall weight of just 442 lbs. (201 kg). The hammer boasts the ability to efficiently operate at pressures as low as 150 psi (10.2 bar) while also being able to deliver an impressive 1600 blows per minute at 350 psi (23.8 bar). Back pressure poses no problems as the C80 ME drills efficiently against high heads of water. Typical horizontal and vertical applications include water wells, caissons, tie-backs, exploration holes, pile/rock sockets, tunneling under roads and other jobs where large volume of rock drilling is required.

Numa is a major manufacturer of down hole hammers and bits for the international drilling industry. The company designs and builds down hole hammers and bits for drilling vertical and horizontal holes 3-1/2 to 43 inches (89 - 1092 mm) in diameter.
