DDPM-PCP (Progressing Cavity Pump)
DDPM-PCP (Progressing Cavity Pump) is an innovative, safe, and reliable custom-designed top drive head. The DDPM-PCP eliminates belts, pulleys, gear reducers and is installed to directly drive the polish rod of the PC Pump. This will in turn reduce failure rates and maintenance costs. The DDPM-PCP can run under extremely low speed range (0.6 - 500rpm) while directly outputting enough torque required by the downhole PC Pump. This will greatly improve efficiency, stability, and safety while reducing noise and footprint.
