PMM PCPs - Advanced Artificial Lift Solutions
overview
ANVEY PMM‑PCP is a next‑generation artificial lift system that utilizes a permanent magnet motor (PMM) to drive a progressive cavity pump without the need for sucker rods. This efficient system delivers 15–98 m³/day per 100 RPM from depths of up to 2000 meters, ensuring high efficiency, deep-set capability, and a long service life even in abrasive, solids-laden wells.
The permanent magnet motor sits at the base of the assembly and provides high torque with low electrical losses. A circulation impeller mounted on the motor shaft continuously moves well fluid around the motor housing, maintaining thermal distribution even at low flow or high viscosity. Above the motor, a high-capacity thruster absorbs axial loads and safeguards the motor bearings from the dynamic thrust generated by the progressive cavity pump.
A specially engineered orbital tube encases a sealed double‑cardan joint that operates fully immersed in well fluid. This joint effectively converts the PCP rotor’s natural elliptical orbital motion into smooth, concentric rotation for both the thruster and the motor. The orbital tube is designed with intake ports that allow well fluid entry while preserving structural integrity and flow efficiency.
The upper section of the system carries the PCP assembly, which is chosen from market-proven geometries capable of managing solids and abrasive production. Additionally, the system is outfitted with flush valves for controlled startup, shutdown, and wellbore cleaning.
A surface controller oversees the entire artificial lift system, providing features such as speed control, torque management, soft-start/stop, overload protection, thermal monitoring, and production optimization. A specialized variant of the ANVEY PMM‑PCP includes a subsurface pressure and temperature monitoring system, which transmits real-time downhole data to the surface via power‑line carrier communication through the motor power cable. This functionality facilitates advanced diagnostics, intake pressure control, and early detection of pump-off, gas interference, or solid loading.
By utilizing the ANVEY PMM‑PCP, operators can avoid the tubing wear, rod wear, and gas leakage issues associated with sucker‑rod‑driven progressive cavity pumps, leading to a cleaner, safer, and more economical artificial lift solution.
