China has rapidly evolved from a consumer to a technology provider in the artificial lift market, especially in progressive cavity pump (PCP) and screw pump solutions for complex oilfields. Within this landscape, a new type of China conical screw pump manufacturer is emerging, focused on all‑metal conical PCP technology for thermal heavy oil, ultra‑heavy oil, and unconventional reservoirs.

Among these manufacturers, Wuxi Hengxin Beishi Technology Co., Ltd. (HXBS) stands out with its IntelliCPCP® Intelligent Conical PCP Artificial Lift System and FERROXIS™ all‑metal conical PCP core.

Why Heavy Oil Operators Look to China for Conical Screw Pumps

Thermal heavy‑oil development in China, Canada, the Middle East, and other regions demands artificial lift solutions that can withstand extreme bottomhole temperatures, corrosive steam environments, and high sand production. Traditional pump suppliers concentrated in North America and Europe have long dominated this niche, but Chinese manufacturers are increasingly recognized for:

• Competitive R&D and manufacturing capabilities in conical PCP technology.

• Strong domestic field testing base in thermal heavy‑oil and ultra‑heavy oil blocks owned by national oil companies.

• Ability to integrate pumps, surface drives, wellhead systems, and digital platforms into complete artificial lift solutions rather than single components.

HXBS exemplifies this new wave of China conical screw pump manufacturers through its integrated IntelliCPCP® system designed specifically for demanding downhole conditions.

HXBS Profile: From PCP Manufacturer to Integrated Solution Provider

HXBS is headquartered in Wuxi, Jiangsu Province, and specializes in advanced PCP‑based artificial lift systems for oil and gas fields. Instead of only offering conventional cylindrical PCPs, the company has invested heavily in conical PCP geometry, high‑temperature metallurgy, and intelligent control technologies.

IntelliCPCP® Intelligent Conical PCP Artificial Lift System

IntelliCPCP® is described as "a complete evolution beyond conventional PCPs," representing a fully integrated rod‑driven artificial lift system rather than a standalone pump. It features the FERROXIS™ all‑metal conical PCP as the downhole core and a suite of proprietary surface and digital subsystems.

Key system design parameters include:

• Compatibility with casing sizes of 5.5 in and larger.

• Daily production rates from 10 to 70 m³/d.

• Pump setting depths up to 1,500 m and well deviations up to 80°.

• Capability to handle water, high‑water‑cut crude, gas‑liquid mixtures, and high‑viscosity fluids typical of thermal heavy‑oil wells.

The system is engineered specifically for high‑temperature and corrosive environments, reliably accommodating material expansion, contraction, and thermal fatigue caused by severe thermal cycling.

FERROXIS™: All‑Metal Conical PCP Engineered in China

The FERROXIS™ all‑metal conical PCP is the centrepiece of HXBS technology and differentiates it from many conventional PCP manufacturers.

Elastomer‑Free Design and Metal‑to‑Metal Sealing

FERROXIS™ completely eliminates elastomers by using a metallic stator and rotor with patented conical geometry and precision surface hardening. This design:

• Creates a dynamic metal‑to‑metal seal that maintains high and consistent volumetric efficiency throughout high‑temperature thermal recovery operations.

• Operates reliably with bottomhole temperatures up to 380 °C and surface ambient temperatures from −35 °C to 45 °C.

• Is capable of lifting ultra‑heavy crude with viscosities up to 20,000 mPa·s at 50 °C.

Conical Geometry and CFD‑Optimized Performance

The conical stator‑rotor geometry enables radially synchronized dynamic clearance adjustment. Decreased clearance can be used to maximize lifting efficiency, while increased clearance opens flow channels for sand flowback and steam/gas/chemical injection.

HXBS uses advanced Computational Fluid Dynamics (CFD) to optimize pump stage geometry, increasing single‑stage differential pressure to around 1 MPa, improving wear resistance, and extending rotor compensation margins. These features are crucial for thermal heavy‑oil wells where pressure drops, viscosity changes, and solids loading vary significantly over the production cycle.

IntelliCPCP® Subsystems: Beyond a Single Pump

As a China conical screw pump manufacturer, HXBS differentiates itself by offering a system that includes surface drive, balancing, wellhead, and digital components tailored to conical PCP operation.

DynaRL™ Drive System

The DynaRL™ Drive System is the surface drive head designed to support IntelliCPCP® operations. It features:

• A bearing housing decoupled from the main drive motor for precise axial movement and enhanced protection against dust, contaminants, and moisture.

• A liquid lubrication system ensuring stable operation from −40 °C to 60 °C, with improved heat dissipation and higher load capacity compared with conventional grease‑lubricated systems.

• A permanent‑magnet direct‑drive motor with rated torque in the 1,300–1,900 Nm range and maximum speed of 200 rpm, supporting high load and high‑temperature operation.

The DynaRL™ lifting assembly executes precise raising and lowering of the sucker rod string, enabling sand flowback, steam injection, and dynamic pump efficiency optimization while incorporating an accurate load cell for real‑time rod‑string weight monitoring.

Graspos™ Balancing Assembly and RodSavior™

For wells with significant deviation and long horizontal sections, HXBS provides the Graspos™ Balancing Assembly. This assembly:

• Dynamically controls the stator‑rotor running clearance by isolating it from axial load changes and lateral forces induced by rod stretch and wellbore deviation.

• Works with the RodSavior™ system to support rod string and fluid weight, mitigating rod buckling and rod‑tubing wear.

Graspos™ withstands up to 60 t of dynamic loading and is engineered to operate at temperatures up to 380 °C, making it highly compatible with thermal heavy‑oil and ultra‑heavy oil wells.

Wellhead Cross Assembly with THERMOLOCK™

HXBS also designs the Wellhead Cross Assembly as the critical interface between surface equipment and the wellhead. It includes:

• A flow cross forged from high‑strength alloy steel and fully API‑compliant, serving as the central conduit for production and steam or gas injection.

• The THERMOLOCK™ Sealing Mechanism, which uses a uniquely designed inverted‑taper stuffing box and a ball valve on the polished rod to achieve a secure metal‑to‑metal seal.

• An Integrated Injection‑Production Automated Wellhead Sealing System that leverages the lifting assembly and control algorithms to execute automated sealing during steam injection, delivering rigless thermal operations.

These technologies ensure fail‑safe, leak‑proof wellhead protection and simplify thermal injection‑production management.

Synergix™ Intelligent VSD and HXBS Monitor

Digital solutions are essential for any modern China conical screw pump manufacturer, and HXBS offers:

• Synergix™ Intelligent VSD Control Cabinet with IP54 ingress protection, E‑coating for superior corrosion resistance, high‑temperature operation up to 65 °C, and an HMI‑based operator interface.

• Built‑in algorithms to handle events such as pump sticking and unexpected shutdowns, rapidly restoring normal production after faults.

• HXBS Monitor Intelligent Control Center, which provides full‑stack real‑time monitoring and advanced data analytics for torque, RPM, temperature, pressure, and other crucial parameters.

These digital tools enable remote multi‑well monitoring, parameter tuning, and optimization of IntelliCPCP® operations, reducing the need for on‑site interventions.

Field-Proven Results from a China Conical Screw Pump Manufacturer
