DT-15 Helical Drive Head

PierTech lists output speeds at both theoretical and actual. Actual torque numbers are NOT listed at 100% efficiency. Maximum efficiencies have been applied to the torque and speed charts according to the manufacturer’s recommendations. Speed and torque output are dependent on the overall system efficiencies associated with the prime mover’s hydraulic system. When the purchaser is determining criteria for specific applications please contact PierTech. PierTech has made every attempt to present accurate and suitable information published in this document. This document should be used for information and comparative purposes only. When application-specific information is required, please contact PierTech.
