MANUFACTURING SOLUTIONS

OUR MANUFACTURING ROUTES

Your technology. Your rotor. Our stator manufacturing expertise.

ROUTE01

01 — BUILD-TO-PRINT

YOUR DESIGN. OUR MANUFACTURING EXPERTISE.

Already developed your rotor and stator geometry? We manufacture precision internally profiled metal stators to your specifications, while you retain control of your design and rotor production.

02 — DESIGN + MANUFACTURE

FROM CONCEPT TO MANUFACTURABLE GEOMETRY.

Developing a new progressive cavity motor or pump? We can support the development of both rotor and stator geometries and manufacture the internally profiled stator. You retain the flexibility to manufacture your own rotors while relying on EC-Profile for the more challenging internal stator geometry.

METAL-TO-METAL

METAL-TO-METAL STARTS WITH THE STATOR.

Replacing an elastomer-lined stator with a precisely manufactured metal profile creates a fundamentally different manufacturing challenge. EC-Profile specializes in manufacturing internally profiled metal stators for OEMs developing their own Metal-to-Metal progressive cavity motors and pumps.

“Your technology. Your rotor. Our stator manufacturing expertise.”

PRODUCTION EXPERTISE

MANUFACTURED FOR THE CHALLENGE

Complex internal geometries. Real production experience.

METAL-TO-METAL PROGRESSIVE CAVITY STATORS

Zero Elastomer / HPHT
Temperature CapabilityField-tested up to 330°C (lab tested up to 500°C depending on material)
Internal Profile Tolerance±0.08 mm on continuous internal cycloid profile
Qualified Alloys4140, 4145, 4330, 1.8550

Manufacturing Advantage: Completely eliminates elastomer degradation in aggressive downhole drilling muds, nitrogen gas (N2) environments, steam injection (SAGD), and high-gas PCP production.

SEND US YOUR REQUEST

A drawing is not required for an initial quotation. Provide the basic stator dimensions, material and quantity below. In many cases, this is enough for us to prepare an initial quotation. For confidential designs, drawings can be exchanged separately by email after an initial discussion and, where required, under NDA.

DIRECT CALL

By submitting this RFQ, your data is protected under our Privacy Policy. CAD drawings (.STEP/.DXF) and models are exchanged securely via direct email upon initial specification review.

24-HOUR RESPONSE GUARANTEE

We will respond to your request within 24 hours.
