Description

Hyvair’s HMS Series Hydraulic Motors (10–16 GPM) deliver dependable power and smooth performance in a compact, orbital design. Engineered for versatility, these motors are ideal for mobile and industrial equipment where consistent torque, controlled speed, and long service life are critical.

Each HMS motor features a robust SAE-A 2-bolt mounting flange with a 3.25″ pilot, simplifying installation and ensuring secure alignment with your hydraulic system. The 1″ straight keyed shaft with 1/4″ key provides positive, slip-free power transmission to driven components such as augers, conveyors, winches, and rotary attachments. Standard 1/2-14 NPTF ports allow easy plumbing into existing circuits and help minimize leakage points.

With displacements such as 080 cu.in. and other sizes in the series, the HMS motors are optimized to operate efficiently in the 10–16 GPM range, delivering reliable torque output and controlled rotational speeds under varying loads. The orbital motor design offers high starting torque and smooth low-speed operation, making these units well-suited for applications that demand precise, steady rotation even at low RPM.

Built for demanding environments, Hyvair HMS Series motors are constructed with quality materials for durability, resistance to wear, and reduced maintenance requirements. Their straightforward configuration and widely used porting and shaft options help lower installation time and make replacements or upgrades simple across a variety of hydraulic systems.

Choose Hyvair HMS Series Hydraulic Motors when you need a compact, rugged, and efficient orbital motor solution that integrates easily and keeps your equipment running productively in tough working conditions.
