3 4 5 Low pressure down the hole impactor for water well drilling

3"-5" Low Pressure DTH Hammers for Water Wells are engineered for efficiency in shallow drilling where air supply is limited. At Hubei Changyangsheng Drilling Tools Co., Ltd., our low pressure DTH hammer units start reliably at pressures as low as 7 bar, making them ideal for portable compressors used in water well projects. These small DTH hammer models feature an optimized valve system that maximizes impact frequency while minimizing air consumption. The air percussion mechanism is designed to reduce vibration, extending the life of your drill rig. Whether for agricultural irrigation or residential bores, this water well hammer delivers consistent penetration in soft to medium formations. Trust Hubei Changyangsheng for DTH hammer solutions that lower operational costs. Our low pressure DTH hammer technology ensures you drill faster with less fuel, making it the top choice for air percussion applications in remote areas. Choose our small DTH hammer for reliable performan

Our 3” hammers are available in the popular DHD 3.5 shank with foot valve type and without foot valve type with HD35A and Mission30 bit shank for operation at higher pressures ranges from 1.0-1.5Mpa.

Features of the with foot valve type:

1. More reliable air distribution.

2. Simple design of the piston, durability performance.

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.
