SPIRA - Power Sections for Downhole Drilling Motors

Higher ROP by increased motor differential pressure. Higher operating temperature. High performance, high temperature NBR & HNBR rubber compounds. Increased longevity / less tripping / to depth drilling. Lends itself to low speed / high torque motor designs. Higher torque at same length of conventional power sections. Shorter power sections at same torque of conventional power sections. Less swelling & stator profile distortion by aggressive drilling fluids. Uniform swelling around stator contour. Uniform heat expansion around stator contour. Minimal stator profile distortion by heat expansion. Excellent thermal conductivity through thin uniform rubber layer and contoured steel tube. Minimal internal heat-build-up no hysteresis. High precision, consistent quality stators and rotors „Made in Germany“.
