Advanced Hydraulics Learning System by Amatrol (85-AH). Covers hydraulic motor applications, hydraulic pump and motor performance, and hydraulic fluids and conditioning. Within this advanced hydraulics training system, learners will study how motors are stopped hydraulically, how to use a pump efficiency curve to determine overall efficiency, how to size a conductor, how to seal materials are determined by the hydraulic fluid type, and more! The advanced hydraulic training system requires Amatrol’s Intermediate Hydraulics (85-IH) and one of the Basic Hydraulics systems (850-H1, 850-C1, or 85-BH).
