The drill pump NB-4 is designed to maintain constant circulation of flushing fluid during drilling.
The rotation from the engine to the pump is transmitted by cellet transmission (for greater reliability and safety, a special six -crushed pulley is used), and the transmission itself is closed with a casing). The belt tension is carried out by screws, and the sleeve for absorption with a snore is put on the pipe and fixed by brackets.
The drill pump NB-4 is good not only with its performance, but also by the possibility of installing on the car chassis. Due to this, he gains high mobility and can be easily transported to the place of drilling operations.
Additional equipment:
- with a gearbox;
- with an electric motor.
