Hydraulic impact hammer
Doofor DF560G is a high-frequency hydraulic impact hammer designed for the use of geothermal and other rotation drilling rigs.
The impact hammer has a rapid function control valve with a large surface for a high percussion frequency and optimal shock wave control. The valve optimizes the power distributed by the piston so, that the impact hammer is capable of delivering a full blow force in all hitting points.
The Doofor impact hammers utilize the Doofor – developed trapezoid impact piston, which increases the movement of the impact pulse in the drill tool string. The two high-pressure accumulators and the low number of serviceable parts make the impact hammers’ uptime a long one. The cast iron body is light and rigid. The four bolt connections in the front make the impact hammer easy to install.
