Introduction

The Staffa HMHDB Series Hydraulic Motor is one of the most powerful high-torque radial piston hydraulic motors designed for severe offshore and marine operating environments. The HMHDB range is engineered for applications where continuous duty, shock-load resistance, precise speed control, and extremely high torque output are essential.

These motors are commonly installed on offshore drilling platforms, deep water winches, anchor handling vessels, heavy-lift cranes, and offshore production facilities worldwide.

SM MARINE SERVICE™ supports customers with new, reconditioned, and overhaul-exchange Staffa hydraulic motors and spare parts.
