Description

The HMS Hydraulic Motors Series 10 thru 16 GPM from Hyvair are compact, high-efficiency orbital motors engineered for reliable power in demanding hydraulic systems. Built around a 250 displacement rating, these motors are ideal for applications requiring smooth, consistent torque delivery within a 10–16 GPM flow range, such as agricultural equipment, industrial machinery, mobile hydraulics, and custom OEM systems.

Each motor features a standard SAE-A 2-bolt mounting flange, allowing quick, straightforward installation and easy interchangeability with common hydraulic motor footprints. The 1″ straight keyed shaft provides a secure, positive drive connection for pulleys, sprockets, or couplings, helping minimize slippage and maximize torque transfer under load. With 1/2-14 NPTF ports, these motors integrate easily into existing circuit designs using widely available hose and fitting sizes, reducing plumbing complexity and installation time.

Hyvair HMS Series orbital motors are designed for dependable performance, offering low-speed, high-torque output with smooth operation and good starting characteristics. Their robust internal construction supports long service life in continuous-duty or intermittent-duty applications, while their compact design helps save space on crowded machines and power units.

Whether you are powering conveyors, augers, small winches, agricultural attachments, or other mobile and industrial drives, the HMS Hydraulic Motors Series 10 thru 16 GPM deliver an efficient, versatile solution that balances performance, durability, and ease of installation.
