These stators are available with any of our premium or performance stators allow you to match a stator to an existing rotor configuration. By matching the ERTcr to a rotor that s already in your fleet, you gain the benefits of our highest performing product without the need to purchase additional Coatings Rotors are commonly coated with chrome or tungsten electroplating of a thin, non-uniform layer across the lobes - Low-cost coating - Polished to remove any surface features - Abrasion tolerantTungsten Carbide high-temperature spray application that results in uniform thickness across the lobes - Impervious to mud effects - Longer service between coatings - Abrasion tolerantNOTE: Rotor profiles are machined specifically for their intended coatings.

7 Changing the coating also changes the intended rotor profile, which may reduce the overall Power section OVERVIEWPAGE Power Sections CatalogFIT OVERVIEWWhen evaluating fit, the main Relevant Environmental factors to consider are: Run Temperature Operational fit Fluid compatibility Wear during runThe goal is to understand the compression percentage . Interference fit between a Power section rotor and stator is calculated as: FITin = ROTavg - S TAm Where : FITin is measured in thousandths of an inch; ROTavg is the major OD of the rotor minus 2 times the eccentricity for even lobe count rotors, or valley-to-crest for odd lobe count rotors, to thousandths of an inch.

8 And STAm is the vector measurement taken in the shop in inches to thousandths of an , FIT% is used to normalize the target compression across stator sizes and elastomers. FIT% is calculated: FITin FIT% = Trubber Where : Truvbber is the stator minor ID minus the nominal tube ID, all measured to thousandths of an expanded equation is: RTOavg - STA m FIT% = S TA m - TUBE id The most basic version of fit analysis only takes into account temperature.

9 For more complex applications swell due to fluids and elastomer wear must be taken into consideration. Target FIT% by elastomer are included in the chart Operational Fits (%)ElastomerLow Power , Shorter LifeOptimalHigh Power , Shorter wears differently than other elastomers.
