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.
ROUTE02
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.
MANUFACTURING FAQ
FREQUENTLY ASKED QUESTIONS
Yes. Our Build-to-Print service is intended for manufacturers who already own their rotor and stator geometry. EC-Profile manufactures the internally profiled stator to your specifications, while you retain control of your design and rotor production.
