Downhole Progressive Cavity Pump

Progressive cavity pumps are positive displacement pumps which depend on the interference fit between the rotor in eccentric motion and the fixed rotor. This forms seal cavities that are disconnected from each other. Through the rotation of the rotor inside the stator, the seal cavities are moved axially from the inlet end of the pump to the outlet. This is how fluid mediums are conveyed using the seal cavities of the pump.

Structural features

1. Small one-time investment

Compared to electric submersible pumps, a hydraulic piston pump and beam pumping unit, the downhole progressive cavity pump is easy to use with a low, one time investment.

2. High efficiency, energy saving

The operation load is stable, with a mechanical loss range small at 75%, and mechanical loss of the plunger and centrifugal pump only at 30-40%. [GF2]

3. Simple structure

The pump body has a small volume, as well as a small transportation and installation space, making it easy to install and keep maintenance costs low.

4. We can provide the necessary equipment such as a shaft driving device, oil pipe anchor, and oil rod centralizer.

Weifang Subtor as a German Subtor invested company in China, offers wide range of progressive cavity pumps and downhole progressive cavity pump. With German supported technology and rich marketing resources, Subtor provides quality PCP downhole pumps with custom solutions for global clients.

Product features

The K class progressive cavity pump was developed according to the needs of customers with space constraints.

1. Downhole screw pump

The stator and rotor are connected to the end of the tubing and the sucker rod. The ground driving equipment drives the rotor to rotate through the sucker rod and lifts the downhole liquid to the surface

2. Rotor

The rotor material of downhole screw pump is mainly 45 steel, 42CrM alloy steel, 2Cr13, 304 stainless steel, 316 stainless steel, etc., which is manufactured by high precision CNC screw processing equipment. The external surface is chrome-plated, wear-resistant and corrosion-resistant. Rotor processing equipment PS1000 introduced from Germany, high processing accuracy, can process single-head, multi-head rotor, size error ≤±0.04mm, processing workpiece up to 10m.

3. Stator

The stator of Sabert downhole screw pump is made of German technology, and its rubber material is mainly NBR, NBRH, HNBR, FKM and other high-performance rubber, which has excellent oil resistance, water resistance, high temperature resistance and swelling resistance.

4. : The ground drive device is the main ground equipment of the downhole screw pump oil production system, which is the mechanical device that transmits the power to the downhole pump rotor, so that the rotor can achieve planetary movement and realize the suction of crude oil

There are two main driving devices of Sabert, namely the new gear direct drive screw pump special ground drive device and permanent magnet motor direct drive device

Product Applications

A downhole progressive cavity pump connects the stator and the rotor of the pump to the end of the tube and sucker rod. The ground drive equipment then rotates the rotor through use of the sucker rod, thereby lifting underground liquid to the surface. This cavity pump is often used lift crude oil under 8000mPa.s, making it useful for most thick oil wells, such as high sand wells, high gas wells, offshore oil field cluster well groups, horizontal wells and more.

Selling point

The Sarpert downhole screw pumping system has a unique advantage: the overall efficiency of the system is more than 55%, making it more efficient than other manual lifting systems. The installation depth can reach 3000 m and the daily fluid flow can reach 350m³/day, meeting the production requirements of most Wells. We can also provide the necessary equipment such as well drive, tubing torque anchor and rod centralizer.

The single screw downhole pump has the following features:

● can pump high viscosity crude oil;

● can pump more solid content of crude oil;

● Low investment cost, high efficiency, less power consumption;

● Simple installation, operation and maintenance;

● Low noise, no pulsation, smooth operation.

Quality control

The company has passed ISO9001 quality management system certification, ISO14001 environmental management system certification, IS045001 occupational health and safety management system certification, to ensure that all aspects of production and processing are strictly controlled by the three management systems, strict requirements, is the basis for Sabert product quality assurance.
