PIONEER ENERGY
SK-EP Brushless Motor Pulse Generator
The EP pulse generator is a bottom set type DC brushless motor pulser compatible with Tensor standards. It uses a motor to drive the ball screw to drive the actuated valve, generating mud pressure pulses. The pressure balance adopts a piston type. The intelligent control driving circuit adopts energy-saving design and intelligent scale, and its excellent resistance to high temperature, high voltage, and high vibration performance makes it suitable for the extreme working environment.

Product Features 


  • Brushless DC motor drive, low power consumption, and fast sending speed.
  • Adopting QPACK packaging for dual vibration reduction.
  • The pulling force of the actuated valve can reach 18KG, suitable for middle LCM. 

  • Piston compensation type, can adapt to even more harsh underground environments.
