    Power Section Diff Pressure (psi)

    Operating a power section above the maximum recommended differential pressure will reduce stator life. Performance Curves are for reference only. Actual power
    section performance may vary depending on the down hole temperature and rotor/stator fit. Performance data are subject to change without notice. Power
    calculation is based on maximum RPM and full torque. Stator sizes subject to change without notice. Copyright 2015 Dyna-Drill. All rights reserved.
