It is a kind of valveless high air pressure HD55 DTH Hammer DHD350R Hammer COP54 DTH Hammer with foot valve.
HD55 DTH Hammer 5" has the following advantages: 1. Valveless air distribution. More reliable. 2. Simple design of the piston, long life. 3. More efficient energy transfer, faster drilling speed, lower air consumption and lower oil consumption. 4. Fewer internal parts, simple structure, longer life, less failure and easier to maintain because all the parts are heat treated. 5. Easy to disassemble because the top sub, the drive chuck and the external cylinder are connected by multi-step thread.
It is a kind of high air pressure HD45A DTH hammer without footvalve, our newest design. It is also one of the most advanced DHD340 DTH hammer in the world.
Our COP44 DTH hammer has the following advantages: 1. Out of the trouble of foot valve fracture and expansion and contraction. 2. Lower energy consumption and higher impact frequency. The drilling speed is 15%-30% higher than the one with foot valve. 3. Simple structure, reliable parts, long life, easy and cheap maintenance. 4. Lower air and oil consumption. The oil consumption of HD45A DTH Hammer is about 10% lower than the one with foot valve.
