Published: Apr 11, 2026

All‑metal conical screw pump companies are emerging as key partners for operators developing thermal heavy oil, ultra‑heavy oil, and high‑GOR reservoirs under extreme conditions. By delivering elastomer‑free conical PCP technology with intelligent control and integrated wellhead solutions, these companies help extend run life, reduce OPEX, and unlock new production envelopes.

Why the Market Is Shifting to All‑Metal Conical PCP Providers

Thermal recovery processes such as Steam‑Assisted Gravity Drainage (SAGD) and Cyclic Steam Stimulation (CSS) drive artificial lift systems into harsh operating regimes. Wells can see bottomhole temperatures up to 350–380 °C, aggressive steam and condensate environments, corrosive species, free gas, and high sand production.

Conventional PCPs with elastomer stators face three major challenges in these environments:

  • Elastomer degradation: Swelling, hardening, cracking, and de‑bonding under high temperature and steam cycling dramatically shorten stator life.

  • Sand‑induced sticking: Abrasive solids bridge in the cavities, causing torque spikes, hard starts, and pump sticking.

  • Restricted operating envelope: As temperature and viscosity change over the cycle, volumetric efficiency drops and torque rises outside safe operating windows.

All‑metal conical screw pump companies specialize in solving these structural limitations by replacing elastomer stators with metal‑to‑metal conical PCP designs and combining them with intelligent dynamic clearance control.

Defining Features of All‑Metal Conical Screw Pump Companies

True all‑metal conical screw pump companies are distinguished by their ability to deliver complete solutions rather than standalone pump hardware. Typical attributes include:

  • In‑house all‑metal conical PCP design These companies own the intellectual property for conical rotor‑stator geometry, surface treatments, and metal‑to‑metal sealing mechanisms capable of operating up to 380 °C BHT.

  • High‑temperature and heavy‑oil expertise They design specifically for thermal heavy oil recovery, ultra‑heavy oil, high‑GOR wells, and high‑sand‑producing wells instead of only conventional PCP applications.

  • System integration capabilities They deliver complete artificial lift systems, including surface drive systems, wellhead cross assemblies, automated sealing solutions, and digital control platforms.

  • Digital intelligence and automation Their solutions incorporate dynamic clearance adjustment, wear compensation, anti‑sticking logic, and multi‑well monitoring via intelligent VSDs and centralized control centers.

Among these companies, Wuxi Hengxin Beishi Technology Co., Ltd. (HXBS) has established itself as a pioneer with its IntelliCPCP® Intelligent Conical PCP Artificial Lift System.

HXBS: A Pioneer Among All‑Metal Conical Screw Pump Companies

HXBS focuses on advanced PCP‑based artificial lift for thermal heavy oil, ultra‑heavy oil, and unconventional developments. The company's flagship offering, IntelliCPCP®, is a comprehensive rod‑driven artificial lift system featuring the FERROXIS™ all‑metal conical PCP at its core.

IntelliCPCP® System Overview

IntelliCPCP® is engineered for oil and gas production operations in demanding environments. The system:

  • Works with casing sizes of 5.5 in and larger, with daily production capacity from 10 to 70 m³/d.

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

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

The solution is specifically designed for high‑temperature and corrosive environments, accommodating material expansion, contraction, and thermal fatigue induced by thermal cycling and extreme downhole conditions.

FERROXIS™ All‑Metal Conical PCP

The FERROXIS™ all‑metal conical PCP is the technological foundation that differentiates HXBS from many other pump providers. It features:

  • A completely elastomer‑free design that relies on patented conical geometry and precision surface hardening to form a dynamic metal‑to‑metal seal.

  • Reliable operation in wells with bottomhole temperatures up to 380 °C and surface ambient temperatures between −35 °C and 45 °C.

  • Lifting capability for ultra‑heavy crude with viscosities up to 20,000 mPa·s at 50 °C.

The pump's conical stator‑rotor geometry allows for radially synchronized dynamic clearance adjustment, decreasing clearance for maximum lifting efficiency and increasing clearance to create flow channels for sand flowback and steam/gas/chemical injection.

Integrated Technologies That Set HXBS Apart

All‑metal conical screw pump companies need integrated technologies to convert pump performance into system‑level value. HXBS addresses this with several proprietary subsystems.

DAGS™ Dynamic Clearance Adjustment System

The DAGS™ Dynamic Clearance Adjustment System is a core differentiator for IntelliCPCP®. It includes:

  • DAGS™‑01 Volumetric Efficiency Optimization System, which uses the surface lifting assembly and control algorithms to dynamically adjust rotor position, ensuring optimal stator‑rotor clearance and concentricity for varying fluid viscosities.

  • DAGS™‑02 Adaptive Axial Wear Compensation System, which continuously monitors pump performance and compensates for wear‑induced clearance enlargement by axially repositioning the rotor once thresholds are reached.

  • Dynamic Clearance Sand Handling System, which enlarges running clearance to keep abrasive solids in suspension and flush them through the pump, preventing sand bridging and sticking.

This allows IntelliCPCP® to maintain the FERROXIS™ pump in its optimal operating state where efficiency is maximized without causing excessive torque spikes.

Graspos™ Balancing Assembly and RodSavior™

Highly deviated and horizontal wells place severe lateral loading on the rod string and rotor. HXBS addresses this with:

  • Graspos™ Balancing Assembly, which stabilizes the rotor‑stator running clearance by isolating it from dynamic axial and lateral loads.

  • RodSavior™ Rod‑Tubing Wear Mitigation System, which supports the dynamic weight of the rod string and fluid column while mitigating helical buckling and rod‑tubing wear.

Graspos™ can withstand up to 60 t of dynamic loading and is designed for reliable operation at temperatures up to 380 °C, enabling deeper pump setting in medium‑to‑deep, highly deviated wells.

THERMOLOCK™ Wellhead Cross Assembly

For thermal heavy oil operators, wellhead integrity and rigless injection‑production capability are top priorities. HXBS addresses these with its Wellhead Cross Assembly that includes:

  • A flow cross forged from high‑strength alloy steel, fully API‑compliant and resistant to high pressure and corrosion.

  • The proprietary THERMOLOCK™ Sealing Mechanism, an inverted‑taper stuffing box and polished rod ball valve combination that delivers a secure metal‑to‑metal seal under precise load.

  • An Integrated Injection‑Production Automated Wellhead Sealing System that executes automated sealing during thermal operations without the need to pull tubing.

This design enables fail‑safe wellhead protection, rigless steam injection, and high‑integrity production operations across all well profiles.

Synergix™ Intelligent VSD and HXBS Monitor

All‑metal conical screw pump companies must also excel in digital automation; HXBS delivers this through:

  • Synergix™ Intelligent VSD Control Cabinet, which features an IP54 enclosure, high‑temperature rating up to 65 °C, and an HMI‑based control interface. It integrates advanced drive technology, sensors, and process control components along with multi‑tiered protection mechanisms.

  • HXBS Monitor Intelligent Control Center, which provides full‑stack multi‑well monitoring, data acquisition, and analytics, capturing torque, temperature, RPM, and other critical parameters.

These digital solutions underpin automated diagnostics, dynamic clearance control, anti‑sticking logic, and remote optimization across entire well pads.
