ELASTOMERS & ROTOR COATINGS
MOTORMAX Drilling motors and tools has developed Nitrile Butadiene Rubber (NBR) for standard requirements and also Hard Rubber (HR) for higher torque requirements. Stators with Oil-Resistant Elastomer (S) are recommended for oil-base muds while High-Temperature Elastomer (T) stator can be utilized at temperatures up to 180°C. In cooperation with Russian Academy of Sciences we formulated new math models which help us select fit-for-purpose elastomer compounds and injection parameters. Rubber compounds are manufactured and supplied by the leading German and American rubber manufacturers with high physical and mechanical properties.
Drilling Fluid Specification
Chlorides in mud can severely corrode chrome plating on rotors and, as a result, deteriorate stator elastomer. Certain additives in mud can have a detrimental effect on mechanical properties of the stator elastomer and severly reduce the life of the stator.
* - higher chlorides content requires a special coating on the rotor (may be custom-made).
** – temperature- and oil-resistant stators may be custom-made.
Salt Concentration
Rotors can be chrome plated in acc. with HEEF-25 process, or HVOF / HVAF tungsten carbide coated with ceramic sealing for maximum wear and erosion protection.
