High Performance
Stator Elastomers

Drilex offers three types of elastomers that form the internal profile of the stator.  All three Drilex stator elastomers are a special formulation designed specifically to meet  the most demanding applications. All component mixing, processing, and stator injection are precisely controlled to ensure a quality blend of the elastomer.  All Drilex stators are manufactured in the U.S.A. under strict quality process controls.

DHR  The premier performance stator elastomer is the Drilex DHR compound.  It is a hard rubber formulation with excellent mechanical properties.  A high durometer compound, the Drilex DHR is designed to achieve maximum power and torque from the power section.  DHR elastomer provides optimal performance for both water-based and oil-based applications and can operate in temperatures up to 300°F and limited exposure up to 350°F.

DHT  The Drilex DHT  elastomer is a compound specifically designed for use in high temperature applications.  It is formulated to achieve maximum life at higher temperatures over the DHR elastomer compounds.  The DHT elastomer can be operated in temperatures up to 350°F with limited exposure up to 400°F.

DST  The DST stator elastomer is an economical formulation for use in less demanding applications.   It features a medium hardness with good resilience for maximum life and versatility.  It is suitable for use in most water-based and oil-based applications.  The DST elastomer can be operated in temperatures up to 300°F.

Superior Rotor Coatings

Drilex offers several types of precision rotor coatings to meet a variety of downhole conditions.  Each coating is specially formulated for use on multi-lobe rotors.  From standard water based fluids to extreme corrosive applications, Drilex has a rotor coating that can withstand your toughest application.

CHROME The industry standard rotor coating is a chromium formulation that is applied to a either a steel or stainless steel substrate.  It is commonly used in applications with little to no chlorides. This historical coating offers good wear resistance and protection in all types of light and medium duty applications.  This coating can easily be stripped and reapplied to prolong the life of the rotor substrate material

XR3 Coating

XR3 Rotor Coating

EN5  The Drilex standard even-thickness rotor coating is the EN5 formulation.  It is an economical coating that is used in light duty applications where corrosion is not a concern.    It has good wear resistance and can be applied to either an alloy or stainless steel substrate.  Like chrome, EN5 can be easily stripped and reapplied to prolong the life of the rotor.

SR2  The Drilex SR2 coating is a direct replacement for chrome.  Unlike chrome, it is applied with an even thickness to minimize rotor profile distortion.  This coating offers good performance and life in most types of light to medium duty applications.

XR3  The Drilex Extreme Rotor Coating (XR3) is a proprietary,  even-thickness, tungsten carbide coating suitable for use in medium to severe applications.  XR3 offers outstanding wear protection and is excellent for use in high chloride applications.  Additionally, this type of coating performs very well in pneumatic applications with very little lubrication.  With a coefficient of friction less than typical chrome plating, XR3 can significantly extend stator life over other types of coatings.   The XR3 coating is an excellent heavy duty coating that does not require a stainless steel substrate.
