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.
DDPM-PJ (Pump Jack)
The Direct Drive Permanent Magnet Motor for Pump Jack’s (DDPM-PJ) couples directly to the Sucker Rod Surface Pumping Unit’s gearbox input shaft with is custom-fit technology, eliminating belts, sheaves, guards and other associated equipment.The DDPM-Motor for Sucker Rod Pumping units increases transmission efficiency by eliminating belt and drive transmission parts, significantly reducing maintenance and power consumption, while increasing the service life of the gearbox and bearings as there is no tensile force or side loading from belts. This is also a very important consideration for operational safety.
